Some additions out of brain as I still remember them, full source code for writing / reading values left on other computor. Gimme 2 days
Dirty values code - but works like a charm on Feretti stove. For reading EEPROM values we must add 0x20 to the address - the stove replies with added value (e.g. 0x7F becomes 0x9F in RX from stove, we still write to 0x7F) TODO: calculate checksum automagically, if checskum is higher than 0xFF then we must substract 256Dec from value - now we MUST know if the value will be higher than 0xFF and calculate accordingly. Confirm working for ~7 days with HomeAssistant.

Hi @cyber-atomus it's working like a charm. I get the correct temp set and pwr. Do you know how I can change the temperature or power from home assistant ? |

A bit dirty write-to-stove values - but works like a charm on Feretti stove (we can't use static array for that).
For reading EEPROM values we must add 0x20 to the address - the stove replies with added value (e.g. 0x7F becomes 0x9F in RX from stove, we still write to 0x7F)
If checskum is higher than 0xFF then we must substract 256Dec from value - now we MUST know if the value will be higher than 0xFF and calculate accordingly.
