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.

Where to buy?

This is written on the main page

"How can you build or buy one?

Buy new complete stand-alone P1P2-ESP-interface): I have a number of factory-assembled PCBs available (with ATmega328P and ESP12F, bus-powered, with enclosure, soldered, pre-programmed, optionally with ethernet, with an option for an external power supply, documented and tested; currently available is version 3, v1.2, which is similar to v1.1 shown above). Please let me know if you are interested: my e-mail address can be found on line 3 of P1P2Serial.cpp."
