Integrating P5729 Wireless Doorbell into Home Assistant

Hi everyone, I’ve recently purchased the P5729 wireless doorbell and am excited to integrate it into my Home Assistant setup. Previously, I’ve used an ESPHome 433 MHz sniffer with a RXB6 receiver and the rc_switch decoder, which worked perfectly with my old doorbell. However, the P5729 doesn’t seem to send any signals that my current setup can detect. I’ve tried all other decoders available, but none have worked so far. The outdoor RF button uses a CMT2150L chip, and I’m curious to know what protocol the P5729 is using or if there’s additional hardware required to receive its 433 MHz signal. The manufacturer hasn’t been able to provide this information, so I’m hoping the community might have some insights or experiences to share. Any suggestions or guidance would be greatly appreciated! :hugs:
