Help on Integration with Kältebringer HVAC

Hey Guys,
I have a question about the Integration of an German Brand of HVAC.
Due to it beeing Black Friday Week the Kältebringer Devices are on Sale and I wonder if they can be Integrated with HA? I didn’t find anythin online on the matter. Only that the Tuya Integration might work. Does anyone have any experience?

I’ve created a component for esphome. It’s flashed on the original wifi module
