Hello everyone, i hope this is something interesting and someone can help me out.
I have a little apiary in the country and because i live in town i don’t always have time to go there to give a check soi’m trying to automate what is the minimum( other important checks on life status are done in person obviously) so i built a little prototype with what i had.
I built a scale with 4 50Kg load cells and mounted them on a aluminum frame and using an esp-wroom-32 i was able to read the weight, i proceeded attaching an AHT20 sensor to be installed inside the hive and a DHT22 for the outside and everything is working very well.
Searching around i was able to fing a useful code snippet to make a tare for the hive, even empty this weights a lot!
Now i was wondering, because when is time to harvest honey i have to put on top of the hive another box, is there a way to create a sort of switches to select the tare?
I mean, having the weight of the hive and the other box is possible to create switches to select what i need to tare like in winter i select only the hive and when is spring/summer i can select 1 or 2 boxes to tare?
i attache the current code and the UI
