Add more then 2 Scales?

[lons81]

Hello

Is it possible to implement more then 2 scales?
Free pins are available for esp8266 and for esp32...
Nice would be 3 to 4 scales for Keg and one for the CO2 tank.

This would be a very big improvement for your project.

Thanks, Lons

I might be possible, there are two things to consider;

1. More scales will require more processing power so the measurement interval will be longer -> affecting precision and detection of changes
2. A redesign would probably be needed on the hardware side to support another type of display (you cannot hook up four displays to the i2c). There is a an s3 board with support for TFT that could be an option. But this is not any hardware I have available right now

So yes it would be possible but it will require a lot of rework of the project. its probably easier to build 2 controllers and create a new case that can support it all.
