Comments

I've managed to discover and configure almost all datapoints, without using Tuya gateway. Some of them require very different value format and took a lot of time to get them work. I got stuck in configuring GreenPower mode switch. It doesn't work all the times. Also there is no way to get to fan_only mode of the climate, but it is present in the device. No datapoint is outputted, when fan_only mode is selected.
I suggest that there is a timer function available, temperature calibration also, but at this point, I didn't manage to make them work.

What does/doesn't work with the external definition?

Fully functional: Power state (ON, OFF), Room temperature, Target temp, Fan speed,
Almost done: System mode (Cool, Heat, Fan only - this one is not working), Green power
Not done: Timer functionality, Temperature calibration
