Hi,
I have bought a P5729 wireless doorbell (Wireless Doorbell P5729 EN | EMOS) and it is working correctly. I want to integrate this doorbell into Home Assistant. My previous doorbell works with my ESPHome 433 MHz sniffer with a RXB6 superheterodyne 433 MHz receiver using rc_switch remote receiver decoder. Unfortunately, I can not receive any signal from my new P5729 wireless doorbell. I tried all other decoders but none of them works. The outdoor RF button contains a CMT2150L chip.
Can someone tell me, what protocol P5729 doorbell is using or what kind of other hardware is required to receive its 433 MHz RF signal? The manufacturer did not answer my question.
