Rfxtrx: i cannot connect to rfxcom device

Hardware
1

I have a problem to connect to the rfxcom device. I have tried

rfxtrx:
  device: '/dev/serial/by-id/usb-RFXCOM_RFXtrx433_A11DA6BF-if00-port0'

cover:
  - platform: rfxtrx
    automatic_add: true
    signal_repetitions: 2
    devices:
      071a000000000101:
        name: Arbeitszimmer

and variations /dev/ttyUSB0, /dev/ttyAMA0, /dev/ttyACM0 (which are listed in the system->Hardware list)

When connected to my pc the rfxcom device can control my somfy covers, but connected to the raspberry nothing happens. Some years ago I’ve managed openhab to work with the transmitter, but home assistant seems not to connect to the device. I have looked in the home-assistant.log but can not find an error even switchng loggin on.

How can I start to seach for the error?
PS: I think I’m not a comlete noobie - I have managed to add an Aqara windows sensor via Zigbee2mqt, mi flora via ESPHome and my rooma vacuum cleaner over wifi.

Hi, any progress on this? Kind of having the same issue…

I have setup openhab with the same device. This works. I know it has worked with home-assistant some years ago because i have tried it then. It seems like someone has broken something in the code :frowning:

There is nothing broken in the code. It works here like a charm… It looks like that your config is not right at the moment.

So I’ve got hassio on a RPI3+ and the rfxtrx works without problems. But I’m migrating to an Ubuntu 18.04 LTS server (amd64) where the rfxtrx doesn’t work. It either does nothing or ends up in flashmode (red led). On the same server/installation/container I have no problem with a Z-Wave stick.
And I do see the rfxtrx in Hassio -> system -> hardware. Logging is not generated (or I do not know where to look for it).

Any hint is welcome :slightly_smiling_face:

I had a working environment 2 years ago. My rfxcom device works with the windows-tool and with openhab. I can open and close my somfy blinds and i could do so two years ago with hassio. But now the rfxcom-device does not work with hassio my somfy blinds.
I cannot see any error in my config. Even having debugmode enabled - I get no error.

I would be very happy if you could give me a hint about a mistake in the config.
