Arnold-n / P1P2MQTT

Monitor and control Daikin/Rotex (hybrid/Altherma) heat pumps via the 2-wire P1/P2 thermostat interface with an ATmega328P, ESP8266, and electronics. The P1P2Serial library and P1P2Monitor program perform low-level bus operation, the P1P2-bridge-esp8266 program interprets data from/to MQTT supporting Home Assistant MQTT discovery. P1P2Serial may also be used for other Japanese Home Bus System based standards: DIII-NET (F1/F2) bus, Mitsubishi M-Net bus, Toshiba TCC-Link, Hitachi H-link, Panasonic/Sanyo SIII-Net, Haier, York, and others.

Hi [your first name - I am not sure if this becomes a public or a private comment],

Many thanks for your contribution, looks good! The changes seem to make sense for my model too in view of the earlier observed values. It helps me trigger the situations to verify, so it is very useful, thanks!

Side note: I am still working on the schematics, will upload minor modifications today, and a galvanic isolated version later (perhaps next week, first need to test).
