I’m just in the process to explore HA as a replacement for my Domoticz RPi solution.
After two days I’m very impressed with HA and I managed to get a lot of sensors working like zigbee, zwave, Xiaomi and YouLess. But I got one issue which I couldn’t solve: my two RFXcom transceivers working.
My current setup is HA installed according to https://www.home-assistant.io/installation/ on a RPi 3B+ rev 1.3 (OS+Container+Core 64 bit).
I used the RFXCOM RFXtrx integration, which allows only one installation of a RFXcom transceiver…
What I did:
I connected the 868MHz tranceiver and imported about 40 (Visonic) sensors, key fobs and keypads. After connecting the second transceiver (the 433 MHz one) I couldn’t get it connected using the RFXCOM integration. The integration failed with the message: “only one RFXCOm allowed”.
Looking in the system log following is logged:

So definitely two devices are connected…
What is the best solution to integrate the RFXtrx433 as a second tranceiver? As I’m currently stuck with a lot of 433 MHz devices as well as 868 MHz devices. (currently this is stopping me from a complete switch from Domoticz to HA)
