Here you find some info about the different options and possibilities of your smart scale. Check it out!
To start the scale, just power it and take a device with Bluetooth (and a web-browser)! Check if there are new firmware-updates first.
The UP↑SCALE PWA - which is a simple HTML-page - will run on all mobile phones (Android, iPhone, Windows etc.) as like as on notebooks or desktop computers. There is no App-download and installation, no registration and not even a internet-connection needed to use the scale. (Well, on Apple devices you need an extra app to use our PWA!) All data will stay local and private! Neither the scale nor the app will send any data to us and nothing will get tracked or stored from us at all! Not even cookies! There is no cloud, there are no subscriptions and nothing from us needed to run the scale! Like that it will still work in 50 years, even without us! Just go sure you've downloaded your PWA once ;-)
The exact requirements and browser-settings for the App you can find here, at our extra info- and troubleshooting page.
This scale will get regular firmware updates to enhance its functions and to add extra modes and options! You can check for updates within the scale app by self - and if you are using the (always updated) online UP↑SCALE PWA, then you also will get a notification if there is a new firmware available! To update the scale, just connect it by USB-C to a computer or notebook, open our update-website and click a button! It could not be more easy!
After you are connected with the scale, you will land directly in the normal, simple weighing mode! Here you already have a lots of additional options - but you also can choose between different scale modes in the menu! Each of them is specially made for different use-cases and includes a variety of different sub-modes and options!
This is the standard scale mode and your starting point if you open the scale App. If you want to weight things - here you go! Additionally you have the following options:
If you have many small things of the same weight, like screws, bags or whatever, and if you want to know how many without counting every single one manually - here you go. In the counting mode you are able to:
Use one of the checkweighing modes if you want to control if the weight of things you are adding (or removing!) from the scale is within a given range. There are 5 different checkweigh- and checkcount modes included!
Save your recipes on the scale, weight all ingredients step by step and up- or downscale your recipes on the fly without any calculations needed! The scale will do just everything for you - just enter your desired weight or amount of portions - and the Recipe Mode will guide you through all ingredients one after next! And if you add too much of something - a click on the button can re-calculate all amounts on the fly! This amazing mode will not only save you a lots of work, it also will make your products more consitant and safe!
This mode allows you to fill molds step by step, just like on a conveyor belt. Perfect if you need to fill up many cavities/bags with always the same amount of something.
Whether you prefer espresso or filter coffee, the coffee-modes allows you to perfect your machine or technique. Use the espresso-timer to monitor the flow-rate of your machine or the pour-over-mode to brew your coffee with the ideal brew-rate every time.
If you like to drink a cocktail from time to time but you can't remember the ingredients and amounts, or if you are a bartender but your stuff can't remember anything - the cocktail-mode gets you sorted!
There is no extra fillweighing-mode, but we have different fillweighing options included in the other modes. All this options will show you a percentage-bar as indication for the right weight - with an extra scale for the last 10% - to allow exact filling even with bigger amounts!
Well, this is a scale - so you can weigh things! Use the tare-button to - well - tare the scale, as example with a container on it.
In the counting-mode you can count things. At first you need to tell the scale how much 1 of the things is weighing:
After that the scale will show you the amount of things on the scale, as like as the total- and the average weight of them! Also you can log and count everything in pieces now.
If you switch on the Takeaway Mode (with the small [↰] button top-right), then the scale will remember how much is on the scale and weigh how much you are taking from it instead of what you are adding. Place a full container/bowl on the scale, hit the button and just count how much you get out from it! (The scale will show you also how much is left on it in that case.)
You can add an unlimited amount of units to the screen. This units will be updated live together with the weight and will be also included in the log-files. You can choose between many preset units - but also add your own, customized ones easily. Here an overview about the different units:
Conversion Units can be added in counting- and weighing mode and can be simply a price per weigh-unit, or the calories of a food product or the amount in milliliters/cups if you are weighing something liquid. Once defined (for example as 4.20 EUR per Gram) this units will be shown on the scale and updated with the weight on it (at 100g == 420.00 EUR, to stay with the example.) You also can setup goals for fill-weighing based on that amounts now! Like this you can automatically calculate, show and track different units additional to the weight live on the scale, show the volume of something or subtract a container weight!
You can add an unlimited amount of units to the scale at the same time! Additionally you are able to save this once defined units together with a name as a THING on the scale in order to reload them with a click later! Like that you can add your custom products, foods or containers easily!
To add a price and to show it live with the weight, simply select one of the currencies from the selection and add the price per gram (or per piece in the counting modes). After a click on the button, the price will be shown on top below the weight and update automatically with every weight change. You also can choose just "🪙" or "💰" instead of $ or or EUR. And for sure you can add multiple currencies at the same time. Like that you can show your price in Dollars, Euros and maybe in Bitcoin at the same time - just as you prefer!
Sometimes you want to show or keep track the amount of something. For example Magnesium in milligrams - even if you run the scale with ounces. With this option you can add the metric amount and the name of the ingredient to show its absolute amount on top below the weight. This is specially interesting for producers of infused edibles who like to mention/track/indicate the exact amount of THC or CBD in milligrams contained in the weighed product on top of the scale.
If you want to measure 100ml of Milk, Honey, Alcohol or Coconut-Oil - or if you would need the weight of your flour, nuts or sugar measured in Cups, Table- or Teaspoons... Then you normally first would need to know the density of the particular liquid and then calculate the weight in grams or ounces manually for every weighing. Well, with google and your calculator - but still... what a mess...
With an UP↑SCALE you simply select a liquid or food-product from the integrated database with the most common kitchen- and laboratory products, or from the additional database with 8000+ food products. Or add an own value here, if your products density is not listed until now, no problem at all. (in g/ml or ml/g) Save everything as a THING on the scale then, and you can re-use it later with one click!
Either way: One click, and the equivalent amount in milliliters, spoons or cups will be shown live with the weight! That's it - no guessing or messing around with measuring cups - you can just weight and log directly in volume now!
You want to weight 2.5 US Cups of corn flour? Simply select it from the database, choose US Cups, and hit the button. The flours specific weight - in this case 0.62 g/ml - will be overtaken from the database automatically and you will see the amount of flour in US Cups live at the scale. Additionally you could now add a weighing goal for the US Cups, in our case 2.5 - and the scale will not only tell you how much you need to weight (372g) - but also will show you a percent-weighing-bar! This indicate the amount you have on the scale in a percentage of your goal - easy to fill 97... 98... 99... 100 percent then!
The percent-weighing-option enables you to define whats 100% - and for the next weightings you will see the percentage of that below your current weight.
This is practical for many uses and specially for bakers a great option! The so-called "baker's percentage" is a dough formula wherein the total weight of the flour represents 100%, and the weight of all other ingredients is calculated as a percentage of that total.
With our scale you not need to do any calculations if you want to follow recipes in bakers percentage - you just add your amount of flour as 100% reference weight - and all the rest works automatically! Just weigh your other ingredients step by step without any extra calculations! No place for mistakes - and more time for cake!
Also this option is very useful for fill-weighing because the percentage will be shown in a live-bar, with an extra scale for the last 10% to allow exact filling even at bigger amounts! And last but not least: You also can do percent-weighing based on a goal of an additional unit instead of the weight! For that check out the Fill-Weighing-Goals option!
If you log/sum-up minimum 2 different things, then our scale will show the amounts of your mix also as a Bakers Percentage Recipe automatically! It was never so easy to create and use this type of recipes! How amazing is that?
Maybe you are on a diet - or you just want to know how many calories, carbohydrates, proteins, fat, saturated fat, cholesterol, dietary fiber, sugar and/or salt (sodium) is in the stuff you are eating every day - or in the recipe you are just mixing? Here you go! By the way: The nutrition values of your different weightings of different foods can be simply logged and summed together with the summing- and logging-function then - and our Traffic Light Rating system will show you how healthy your recipe is in that case! Additionally you have a couple of options how to select, insert, save or output this values, check this out:
Simply use the search-option to select one of more then 8000 food products with their most important nutrition values from our inbuilt database! With one click you can overtake all nutrition values and the name of the product to the scale - it could not be more simple!
Its very easy and fast to add own food products with custom values to the scale! You simply can add one (or more) of the nutrition values directly live to the scale - but you also can add all the info for your most used food products easily, add a custom name, and save them as a THING on the scale. Next time you can load it directly from there with a click!
Carbohydrates can be counted also as Bread Units (1 BU = 12g carbohydrate) or as Carbohydrate Units (1 CU = 10g carbohydrate). People with diabetes often use CU or BU instead of gram to calculate their insulin doses. If you have Carbohydrates on the display of this scale, you will be able to show them directly in CU or BU, and also the logging/summing will include the amount of that selected unit later! Like this you see live how many Carbohydrate-Units you have on the scale at the moment - and altogether in the pot! No calculations needed any more - even if you weigh in Ounces!
If you log your weightings with nutrition value units - like fat, saturated fat, sugar and salt (sodium) - then you will find an indication for the "healthiness" of your composition. We are using the common food traffic light system to show you if the values are 🔴 high, 🟠 medium or 🟢 low and how much of the ingredients you got per 100g (or milliliter).
You want to add a price in a strange currency which we do not have in our list? Or maybe you like to show the percentage of love, included in every ounce of your product? Or the amount of single Raisins in a piece of cake? No problem at all! You can add a own unit, a name for it and the amount - and for sure - you can add as many units you want! Btw. The amount can be added:
Here you can subtract a know weight. For example: If your container, bowl, bag or jar is already filled with your weighing goods and you don't like to refill everything to tare the scale with the empty container. Here you simply can subtract the weight of your container from the total weight on the scale.
Tip: Best to add your most used kitchen containers/bowls once with this option and save them as a THING to the scale. Then you are able to reload them later with only one click and you don't have to remember their weights any more!
Extra-Tip: You can add your storage tupperware/containers for your different foods/ingredients as a THING including all additional units like prices, nutrition values etc. Like that you simply can load a product, together with your units and its container-weight with just one click. Just take the tupper from the kitchen cabinet, place it on the scale and see how much is left in there!
If you use the Takeaway Mode now, you simply can weigh, count and log what you are taking from the container - without the need to remember or calculate anything!
If you add a unit to the screen, for example 3.57$ per gram, then you maybe want to know how much would be the weight for 420.00$ now - for example to fill a bottle exactly with that amount.
You can add a goal for any active unit if you click on the "🥅"-Button (top-right of the amount of an active Unit). Simply add your desired amount of that unit there (in our example 420 $) and click the button. Now a percent-weighing option will be shown at the page and you can see a nice live percent-bar which will indicate the amount in proportion to your goal! This is also very useful for manual fill-weighing by the way...
If you hit the (∑)-Button in weighing- or counting mode, the current weight will be added to the log-file! After you have removed the logged goods, the scale will tare automatically and is ready for the next weighing. (In the Takeaway Mode the scale will jump to 0 automatically and also will show you how much is still left on the scale or in your container!)
Optionally you can add a name for your weighed product before you sum up, in that case it will be overtaken to the log-file to make it better readable later.
All units/conversions will be logged and summed, too! Like that you will get not only an overview about what you have weighed, you also will see how much was the costs, ingredients or nutrition values for each of the weightings - and altogether!
If you count sugar, salt, fat or saturated fat, we will add a 🚥 Traffic Light Rating, to show you, how healthy your mix got (and how many percent of everything are inside)!
If you have weighed and logged 2 or more different products/things, then we will show you also the amounts of them as a Bakers Percentage Recipe! This is not only useful for baked-, but actually for all recipes. This way of recipe creation make it very simple to re-use your recipes later-on, for any batch sizes, and without any extra calculations for all the ingredients! Give it a try, you will love it!
You can use the servings-calculator to calculate your portion amounts and sizes based on a weight, a number, on the amount of an ingredient - or by a price, for example! It also will show you the amount of all logged conversions/units for your calculated portion-size - ideal if you want to create labels for your products!
Portion Sizes / Servings can be calculated for:
The portions-calculator-bar will be shown/visible below the log-file, as soon as you have logged something. Insert your desired portion-size or amount, click the "🧮-Button" and your calculation will be shown below the portions-calculator-bar in a seperate box!
Add a "virtual weight" to the scale - or remove it! This can be helpful for many things:
You can save THINGS on the scale, to re-load them from there later.
With THINGS you can save your containers/bowls to remember their weight for later. Or add just a name and a price. But you can also save your storage tuppers/jars of food or weed, including their nutrition values and ingredients to check later how much you have without taring/unfilling/refilling everything first. (And to weigh directly out of that containers with the Takeaway Mode then). Or just save your common kitchen foods including their nutrition values like calories, proteins etc., to reload them later fastly! The options are endless!
A THING need a (unique) name, which you can enter on the page - and also at least one conversion/unit, like a price, nutrition value or a container weight. Then you just hit the ➕ ADD button to save it permanently on the scale. Now you are able to load this THING at any time to any mobile/device, just click the ⚖ LOAD button and select the THING from the list.
You can save up to 1000 THINGS on the scale, each THING with a maximum of 20 Conversions/Units!
The recipe mode enables you to create recipes consisting of 2 or more ingredients including their amounts in proportion to the total weight. After selecting one of the recipes and inserting the desired weight to produce, the recipe mode will guide through the weighting process for all ingredients.
To create a new recipe, open the add-a-new-recipe page and simply add:
And then, for each ingredient:
Import recipes from calculators or 3rd-party websites with 1 click!! For example, you can use the free 420BASE.net Edibles Recipe Calc-O-Lator to create your recipes, and then just export them with one click to your scale from there! Try it out, it could not be more easy!
If you select one of your recipes (or start it directly from the input form) you first will get asked about the total amount you want to produce. If you have indicated a portion size for your recipe you can insert the amount of desired portions now. Otherwise add the total amount you are going to make. The needed amounts for all ingredients will be shown - check if you have everything - and start the program.
Within the running program you also have a couple of options:
You can pause a weighing process at any time in order to repeat it later. For example if you have parts which should react over some hours before adding the next components to the mix. Simply click on the pause-button, optionally add a name, and thats it. Now you can select the paused recipe from the list of all your recipes.
You are able to save up to 250 recipes including max. 50 ingredients each - directly on the scale! Like that you can use your recipes from each connected device without the need of any online-accounts or logins somewhere! Just plug your scale, connect with a mobile or notebook, load your recipe list from the scale and start working!
The factory-mode allows you to fill molds, one after the other, always with the same amount of filling, while counting, taring and logging everything automatically for you!
Setup your molds with the
You can save up to 42 different molds directly on the scale! Simply check the box while defining a new mold. Now you just can select them from your list to start filling them again.
Within the program the scale will give you info about the amount of already filled molds and cavities as like as the average amount of filling for each cavity and mold. Like that you get a nice overview of how exact you was working at the end, as like as a sum of all used product, milligrams etc...
Monitor your espresso machine with the Espresso Timer, even if your scale does not fit under it! Optional automatic-options can detect cups, the first drops of coffee and the end of the program - just place your cup on the scale, start the coffeemachine and the rest will work automatically!
If you prefer filter coffee - make a perfect brew every time with our guided Pourover Mode! The scale will ask you to weight your hardware, it will help you with the right amount of coffee and guide you through the brewing process.
The cocktail mode is not only great if you just want to make a perfect cocktail from time to time - but also if you run a bar! Just add your own recipes directly to the scale and your staff is able to replicate them without any special schooling!
Like at the Recipe Mode, you are able to create your own recipes. Or search and import them directly from cocktail databases! For more detailed info about how to create a recipe, check out the Recipe Mode, its the same, just for food instead of drinks!
The Cocktail Mode will guide you through all the cocktail making process! Step by step it will ask you to add the ingredients, and its check-weighting-options will help you to fill the exact amounts!
Here you can check if things have the right weight or amount - or you can use this modes to weigh what you get off from the scale instead of what you put on! (for example to fill bags without the need to weigh each single one every single time.) The checkweighing-programs will indicate if the amount is perfect (or in an optional OK-range) with colors and - if you like - with a sound. A percent-bar also will show how close you are - very useful if you are using this option for a manual fill-weighing! Also the scale will tare, count and log for you automatically in the checkweighing modes!
Simple checkweighing. Add things to the scale, and it will show you if its (and how much) too much or too less. Then you can remove the things again manually.
Compare the weighing item with specified limit values. (the target weight and optionally a range for OK and PERFECT). If this limits are exceeded or undershot, it will be highlighted and shown on the display. Positive checkweighing determines whether the weight of the added material is within the target range. Similarly, negative checkweighing checks the weight of the removed material.
In check counting, it is not the weight but the number of pieces that is compared with limit values. You can add the amount of pieces as like as the weight for one of it - and the scale will do the rest! For sure we will show you not only the difference in percent, but also in pieces and as weight!
Auto-Overtake: Perfect weights can be overtaken/counted automatically after a given amount of time or with a click on the button.
Counting / Averaging: If counted per button or automatic option, a total weight as like as the average amounts of everything will be shown automatically!
This scale is operate-able with plenty of weighing units and in different languages! Calibration is fast and simple! Also it will allow you to operate it with multiple displays and devices at the same time, it even can be connected with your home automation systems or other devices!
Within the app you are always able to switch between weight units or to select a different language - but you are also able to save your preferred settings directly on the scale in order to load them automatically - independtless of the device you are using to connect with the scale! Go to the SCALE ⚙ SETTINGS page to change your settings and save them on the scale directly!
This scale is able to weigh in Gram as like as in many other units. Ounces or Pounds? No problem! We even can weigh in Eights! (No joke!) But also you can find all the other more or less common or useful units, like Carats, Troy Ounces or - for our American friends - Giraffes per Footballfield.
And by the way, its also possible to weigh directly in volume, such as Milliliter or Cups, regardless of the scales weight unit!
At the moment the scale software is available in English, German and Spanish. A French and Italian version will follow soon - and many more later! You can change the language on the fly, or save your preferred language on the scale at the settings page.
Speech Output: You can switch on a speech-output! The scale now will read out loud the current weight each time it has changed! Depending to your selected language, device and browser you maybe even have different voices and dialects to choose from!
Its generally not a bad idea to re-calibrate the scale from time to time, specially after not using it for a long time or if you travel with it... Our inbuilt calibration program will make things easy for you.
Single-Point: You just need to have known weight ready to hand - then click the button at the settings page and follow the instructions! For a single-point-calibration, ideally use a weight which is min. a third of the range of the scale!
Multi-Interval / Multi-Range: Optionally its possible to calibrate the scale with multiple weights! This option will make the scale even more exact over its full range! You can use a 2-point-calibration or even a 3-point calibration which makes your scale a real multi-interval-scale (Well, we're always showing the smallest, best possible interval - but with a higher precision then, based on the current gross weight). In this case you will need a separate known weight for each calibration-step, but no worries, our calibration wizard will guide you through that!
PS: Your scale will come pre-calibrated with 3 different calibration points from the factory!
If you are running a 232 UP↑SCALER Scale Adapter, then you can/should setup your scale once in the RS232 Scale Settings! Here you are able to configure the serial connection to your scale as like as the precision, the capacity and how you are going to tare the scale.
You have the option to allow (or disallow) the connection to the scale for multiple devices! This can be very useful if several persons are using the same scale at the same time - but could course trouble in public environments, so you can decide when you need it. Also there is a Weight-For-Everybody function. If this option is on, then the current weight or count on the scale will be continuously send via the public manufacturer data of the scale and can be read from every device nearby - without any prior connection to the scale! (Same like the find-me or iBeacon devices). Beside of that you will find multiple options to transmit data and receive commands via USB (Serial Port) and/or WiFi (ESP-NOW)! (To connect with scale software, printers or own devices!)
You are able to control all the sensor- and averaging settings which are controlling how fast and exact the weight will be shown. You can keep all settings at automatic, but sometimes you maybe want to change something, for example to stabilize the weight better if you are in a windy environment. Click here to read more about this expert-scale-settings.
If you connect with your scale, it will identify with a number (like #45678). This number was randomly generated at the first start of the scale and is only stored there, we do not know (or store) it at all. If you don't like your number, or if you want to change it for any reason, select the checkbox at the settings page and a new number will be generated for you!
Yes, you can connect more then one scale at the same time!! Just connect an additional scale within the app and weight on all of them simultanely! Maybe you are using a big platform scale together with a smaller tabletop one? Just connect them both and track all ingredients at the same time and in the same program!
This scale can send data and receive commands via USB, BLE and WiFi to ensure connectivity to old and new software as like as to own programs and microcomputers! All this options you can switch on/off and setup in your App, at the SCALE ⚙ SETTINGS page in the USB, BLE & WiFi Stuff section. Here some more detailed info about the possibilities and data formats for...
You can control the scale from your mobile/computer via BLE with your app. Normally its only allowed to be connected with one Device at the same time, but you also can use multiple devices at the same time if you need so! Switch on the Multiple masters option to do so, but take care in public with that!
If this option is on, the scale will send weight data continuously to everybody! This is working like a FindMe Device, the data will be packed in the public readable manufacturer data part where it can get read out from everybody nearby! This can be super-useful if you want to read out this data from multiple devices without connecting/pairing first! This will allow some additional options, like showing the weight of multiple scales together at the same time - or you could read it out with your smart-watch or integrate it into your home automation systems on that way! The data by self will be transmitted as ASCII in HEX - check out all info about the exact format below!
We've prepared a small and simple example "sketch" for Arduino. This will scan for scales around you and show the live weight on it - without being connected/paired to a scale first! Check this out to learn how to scan for the scales and how to read in and use the weight data. Click here for the ARDUINO BLE WEIGHT MONITOR, copy, paste and there you go :)
PS.: If you also want to get more (or faster) data, and if you also want to be able to send commands to the scale, check out the WiFi/ESP-NOW options for ESP Microcomputers instead!
Same is working via Web-Bluetooth directly in a Web-Browser! We've prepared an example just with html and javascript which is reading out - and summing up - all scales around you! Click here to check it out (and to test it live and direct). Just copy the code from there and build something own on it :)
If you switch on the USB SERIAL OUTPUT at your scale settings, then you are able to send live data from the scale via the USB port - and also to receive commands (like TARE) via USB! For the USB output you have several different options:
We are sending with: 115200 Bits/s; 8 Data Bits; NO PARITY; ONE STOP BIT
In this 2 modes, the data will be delivered as ASCII in HEX! This is for the old-school computers and scale software. Optionally you also can switch to a plain text ASCII output! Check out the EXTENDED++ Mode for exhaustive outputs as readable data for modern data-loggers etc.!
In bidirectional command mode (ON REQUEST), the weight can be immediately retrieved by sending the command "Q" followed by Carriage Return and Line Feed to the scale. The next stable weight can be requested with "S" and will be received once after stabilization in this case. If you send "T" you can tare the scale.
| Nr.: | 1 | 2 | 3 | 1 | 2 | 3 | 1 | 2 | 3 | ||
|---|---|---|---|---|---|---|---|---|---|---|---|
| ASCII: | Q | CR | LF | S | CR | LF | T | CR | LF | ||
| Hex: | 51 | 0D | 0A | 53 | 0D | 0A | 54 | 0D | 0A |
The Scale always sends 19 bytes for every measurement. This are ASCII characters as HEX (or optionally as plain ASCII characters as decimals) in the following format:
| Nr.: | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| ASCII: | U | S | , | - | 0 | 0 | 0 | 0 | 4 | 2 | 5 | . | 9 | 8 | g | CR | LF | ||
| HEX: | 55 | 53 | 2C | 2D | 30 | 30 | 30 | 30 | 34 | 32 | 35 | 2E | 39 | 38 | 20 | 20 | 67 | 0D | 0A |
| DEC: | 85 | 83 | 44 | 45 | 48 | 48 | 48 | 48 | 52 | 50 | 53 | 46 | 57 | 56 | 32 | 32 | 103 | 13 | 10 |
The first 2 characters are the header
| 1 | 2 | |
| S | T | Stable Weight (Weighing Mode) |
| U | S | Unstable Weight (Weighing Mode) |
| S | Q | Stable Quantity (Counting Mode) |
| U | Q | Unstable Quantity (Counting Mode) |
The header is separated from the measured value by a comma.
The measured value consists of 11 characters and always begins with a sign (+/-; + is used for a value of zero). The measured value is transmitted right-aligned, unused positions are filled with zeros. The decimal separator is a point by default.
After the measured value, 3 characters for the unit are transmitted. Also right-aligned, with spaces for unused characters. The last 2 characters are always a CR/LF (Carriage Return/Line Feed) and indicate the end-of-line.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | |
| S | T | , | + | 0 | 0 | 0 | 0 | 2 | 3 | . | 4 | 2 | 0 | o | z | CR | LF | 23.420 oz (stable weight) | |

| U | S | , | - | 0 | 0 | 0 | 0 | 0 | 0 | 3 | . | 9 | 1 | g | CR | LF | -3.91 g (unstable weight) |
We've also prepared some code examples for html/javascript and Arduino which will read in this data wireless! Use this scripts to see how to receive and process this data via BLE!
This mode will blast out weight data 40 times each second via the USB Serial Port (1 line each 25 milliseconds)!
Its possible to select between- and show up to 7 different weight-data-points from the scale at the same time, starting from the raw sensor data, via the unfiltered and filtered averages, up to the final weight on the display! (Also a raw gross weight is available!). Additionally/Optionally you can add a 3-line-summery every second about the amount of grabbed data-points within the last second, including their deviations! Otherwise just leave this untouched.
Use this mode to connect to data-loggers etc. to output the weight as live graph or so, or to monitor the scale with a serial monitor - for example to fine-tune it with the extended scale settings. Or, if you want, build your own software with our scale! Btw.: This data will NOT come as HEX, like the simple output, but directly as human-readable ASCII text!
You are able to connect up to 5 WiFi devices via ESP-NOW. This standard will transmit data by WiFi, but without the need of internet, a rooter or any passwords or logins! Just add the MAC-Address of the peripheral to the scale once, and everything is working as soon both devices are powered! It could not be more simple!
To connect ESP-NOW devices, which could be our peripherals or your own microcomputers, simply switch on the WiFi-Options at your scale settings page. Select a send interval and the WiFi channel, add at least one MAC address - and ready you are! Check out the following example code if you want to program your own device!
If you like to create your own device based on an ESP32 or ESP8266 microcomputer, you're welcome! Receive live data from the scale and simply show it on a display - and/or transmit it to some other devices, monitors, relays, home-automation-systems or to your website! Here you can find a small example sketch, the [UP↑SCALE MasterBlaster], made for an ESP32 at the Arduino IDE. This small script receives live data and will send commands on button clicks. Check out how (and what kind of) data is incoming from the scale, and how simple it is, to send commands back. Use this as inspiration and example/base for your own programs :)
If there are no connected devices around you (any more), then the WiFi module of your scale will automatically shut down to save energy. In that case you would need to restart the scale to start transmitting WiFi data again (just unplug and plug the scale once). You can set up this standby/shutdown time by self (standard is 5 minutes) or you can switch to "Always ON", if you don't care at all!
Weighing things is not as easy as it maybe looks ;-) Measuring weight digitally in real life is quite interesting actually, if you break it down. To explain it fastly, our digital scales is made from 3 main components, a Microcomputer, a analog-to-digital converter and a so-called load-cell. Inside the load cell - which is this is a transducer whose function in the scale is to convert the force exerted by the object of measurement into an electrical signal - is a set of strain gauges arranged like the resistors in a Wheatstone bridge. When a load is placed on these strain gauges, they compress. This compression changes the resistance of the gauge, just like in a Wheatstone bridge. Now there will be a voltage output corresponding to the change from the stressed gauges - which we will transform to a digital signal, with the help of a Sigma-Delta analog to digital converter, to be exact. This digital signal we can use now to calculate the weight.
But - and here it gets complicated - there are many variables! There is nothing like an absolute and always same weight of a thing, it depends how, how long and where you are weighing it, how the conditions are around, if the thing is maybe moving and and and... Because of that there are many variables in the background which define how the weight will be read from the sensor, how the data will get stabilized and displayed, when the weight is getting "stable", what you define as stable weight, and so on and so on... The output at the end should not jump around too much, should be reliable and repeatable - but also need to be shown as fast as possible. While normal scales do everything automatic for you, and normally need to find some kind of compromise, professional scales will let you adjust some-, and our scale will let adjust you all of this settings! Maybe you want your scale faster reacting for filling things - or you need a long average weighing time because you need to weight some moving animals or maybe you need the scale a bit less reactive because you are working outside or people are bumping on your table all the time! With our scale this is no problem at all, you can adjust every single variable - or just leave it in the automatic mode!
This Settings you will find within your scale-app, at the Scale-Settings page. Here you can define how fast the sensor should be, how it will calculate the averages, how long it will take to define the weight as stable and if you want to ignore, for example, small bumps on the display - and how big they can be.
