I've been building a scale for my keezer based on cheap hardware. There are quite a few projects on Github that shows how to build a simple scale on HX711 and load cells. But what I found that those are not really that stable over time and most software was not accurate enough for my needs. On my first builds it could shift 2 lbs over a 24 hour period which is not good if you want to implement advanced features. There are a few other projects that will provide excellent data quality like KegCop but I didnt want to have any sensors on my beer lines (and those flow sensors was really expensive in Sweden, more than 25 times more expensive than load cells.
I ended up with this setup so far: ESP8266, 2 x HX711 + Load Cells and 2 x 0.96" OLED displays. 3D printed scale bases. One build supports 2 scales.
I'm quite happy with my build so far since I think I managed to fix a lot of the stability issues. I have not really put that much efforts in to the documentation as with my other projects.
So my question here is if there are anyone that is interested in this type of build and would help to give feedback in order define the future path of the project.
Would you be interested to build this ?
What features would you like to have ?
These are the features that I have done so far:
* WIFI Enabled,
* Web based configuration
* Simple scale calibration via web interface (3 steps)
* Stable level detection (will filter out sudden changes of the hx scales)
* Ability to detect the pour of a beer (min 10 cl)
* Histogram over the last level changes and pours.
* Push changes to brewspy (pour and keg volume)
* Get brew/beer data from Brewfather (Beer name, abv, fg, ebc, ibu)
* Choose size of a glass of beer (so that the weight is correctly converted to remaining glasses)
The project can be found here;
