P1P2Serial
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.

Home Assistant 2023.11
Yep, I'm relatively new to Home Assistant but love it. Combined with ESPHome, I've got most of the lights in my house controlled (via switch changes, not smart bulbs), and my all my air conditioners via the MHI-AC-Ctrl project[1,2] (which is fantastic - ordered the boards from JLC-PCB, parts from Ali-Express, told ESPHome to program everything and plugged them into the ports and...it all just worked!).
Just got a Mitsubishi Electric (which is different to MHI) and a Daikin at my parents house to get online - but code for both exists and I suspect the MHI boards can be reprogrammed to fulfill the role without any hardware changes.
It's incredible that the future we wanted in like, 2010 can be had and had without selling your soul to the cloud: I can leave the house, and turn off all my lights and AC's while walking out the door, or get notified if I've left my garage open - without a single cloud provider dependency, all open-source.
