[BK7231N] Linptech G6L-WIFI self-powered wireless doorbell, CBU version

Hi everyone,

The Linptech G6L self-powered doorbell has a Xiaomi and a Tuya compatible version, the latter ships with a CBU, but besides that, the hardware is the same:
It has a CMT2217B OOK RF receiver and a SZY8039B doorbell chime chip. Everything is documented for the Xiaomi version, which has an ESP32, and the chime chip works via libretiny ESPHome on the CBU, but the RF receiver does not. I have connected the RF module to an ESP, then it works fine.

The protocols used and the implementation in ESPHome:

Is it possible to support it by OpenBeken?

Sure, I will be happy to add support of this device. It's just that I don't have this device at hand. Would you be able to help with testing, maybe also provide some help with C code as well?

The same goes with RF driver, I think.

As for the C code, I am a beginner, but I am happy to help with the testing.

Cześć, ja mam ten dzwonek i mogę go wysłać aby była opcja uruchamiania go pod openbeken
