This is code to run on an ESP32 module and connect to a Daikin aircon unit in place of a BRP069B41 or BRP069C41 module.
- KiCad PCB designs included
- 3D printed case STL files
- Documentation of reverse engineered protocol include
Basically, Daikin have gone all cloudy with the latest WiFi controllers. This module is designed to provide an alternative.
- Simple local web based control, easy to save as desktop icon on phone
- MQTT reporting and controls
- Works with https://github.com/revk/ESP32-EnvMon Environmental Monitor for finer control
Git clone this --recursive to get all the submodules, and it should build with just make. There are make targets for other variables, but this hardware is the make pico version. The make actually runs the normal idf.py to build with then uses cmake. make menuconfig can be used to fine tune the settings, but the defaults should be mostly sane. make flash should work to program. You will need a programming lead, e.g. https://github.com/revk/Shelly-Tasmotizer-PCB or similar, and of course the full ESP IDF environment.
The wiring from the existing wifi modules fits dire 56A8 ctly (albeit only 4 pins used).
