I was looking around for a device handler to simply control my Mitsubishi air conditioners direct via the SmartThings Classic app while also still being able to use my IR remote as well.
Unfortunately I couldn’t find any solution without using MQTT.
So I finally created my own:
How it works:
Basically you need an ESP32 board connected to your Mitsubishi air conditioner’s CN105 port.
The device handler than communicates via hubAction’s with the ESP32 which than talks to the air conditioner.
Hope this will help some of you too.
The project is still in an early development stage, so feel free to give feedback for further improvements.
