Based on https://github.com/rjdekker/MHI2MQTT
Monorepo for building a MQTT interface for Mitsubishi Heavy Industries (MHI) SRK/SRF series air conditioners.
I started with almost nothing and needed to buy some extra stuff to complete this project.
- platformio - for uploading sketches (VSCode recommended)
- MQTT broker like Mosquitto or hmq
- MQTT explorer - for debugging
Before starting this project be aware that:
- Opening the airconditioning device may void warranty!
- The device is using high voltage!
- The terminal to plug in the CNS connector is difficult to reach in most cases.
Ok, let's go 😄
- Adjust FTDI adapter
- Solder Arduino pin headers
- Flashing Arduino
- Flashing and configuring WiFi shield
