Hello,
I just bought the 433 Mhz temp/Hum sensor in topic, hoping that my rfxcom integration would be able to connect to it, but it does not budge.
I already tried to enable debug logging as explained here: RFXCOM RFXtrx - Home Assistant => nothing
2025-10-30 19:27:32.426 DEBUG (Thread-21 (_connect)) [RFXtrx] Status: Status [subtype=433.92MHz, firmware=6, output_power=28, devices=['hideki', 'lacrosse']]

I played around with the different protocols, but also no luck.
This is a problem that is somewhat related: Temperature sensor TFA Dostmann 433mhz - Rfxtrx - Event is not JSON serializable but I don’t know how he gets the “logger” from homeassistant.components.recorder.core. If I could get to that info, I could maybe add the sensor manually?
The sensor has a tx button to initiate a signal, but nothing to see in the reception logs.
TFA is in the supported rfx sensor list: https://www.rfxcom.com/WebRoot/StoreNL2/Shops/78165469/MediaGallery/Downloads/RFXtrx_User_Guide.pdf
Anybody any ideas?
