Yes, all discovered items will show up there. So will all configured items and integrations.
If your device isn’t showing up in the dev tools/states page, then it’s not connecting to the device and seeing it. You probably had an error message in your log on startup if that’s the case, and you should do a little bit of troubleshooting to find the problem.
Not all protocols as advertised are enabled on initial setup of your transceiver. Enabling all protocols is not recommended either. Your 433.92 product not showing in the logs? Visit the RFXtrx website to download RFXmgmr and enable the required protocol.
Have been changing HW from a Raspberry Pi to a Ubuntu machine, Hassio in Docker.
I transfered my configuration from the Pi to the new plattform.
The RFXtrx where working on the Pi, meaning that I have enable the protocal before.
Do I need to that again?
Now when I have a new plattform but the same configuration of Hassio.
This problem started when I changed plattform for the Hassio. From RaspberryPi to Docker on Ubuntu.
Could it have something to do with the Docker setup?
Did you disable uninstall modemmanager on Ubuntu. I know this is required for ZigBee stick to work on Ubuntu/HA. It might be required for your rtxrfx stick as well.
The modemmanager package will interfere with any Z-Wave or Zigbee stick and should be removed or disabled. Failure to do so will result in random failures of those integrations. For example you can disable with sudo systemctl disable ModemManager and remove with sudo apt-get purge modemmanager
