Hass.io 0.70 - RFXTRX Error

Installation Home Assistant OS

I’m just in the process of downgrading my config to 0.69.1 because I just updated to 0.70 and now I’m getting a RFXTRX error:

Change rftxtrx in configuration.yaml:

rfxtrx:
device: /dev/ttyUSB0

Oh! Cool, I’ll give this a try.
Was this a ‘breaking’ change that I missed in the release notes?

4

Also on my Home assistant container the folder; /dev/serial/by-id/ is gone.

Any idea how to fix?

Same issue for rflink
That is I can no longer see anything in /dev/serial on hass.io

Change rftxtrx in configuration.yaml:

rfxtrx:
device: /dev/ttyUSB0

Hi,

Have you tried this and know if it’s working?

Hi,

I can confirm that this is working by running hassio under Ubuntu 16.04

8

This isnt a solution for me,
I’ve multiple USB devices and after a reboot the number is variable
So sometimes its /dev/ttyUSB01 and another time its /dev/ttyUSB00…

I can also confirm that this work under Ubuntu server.
Someone should update the component site:

My RFxtrx433E transceiver have stopped working since update to >0.70. I don’t get any error sin log but all my 433MHz sensors have disappeared.

I have tried different ways to specify path in configuration.yaml. Could someone please tell me what command in putty I need to show the correct path to the RFXtrx?

I had a similar problem with RFLink to solve this I ssh’ed into HASSIO and ran:

hassio hw info

I got:

{
    "result": "ok",
    "data": {
        "serial": [
            "/dev/ttyACM0",
            "/dev/ttyAMA0"
        ],
        "input": [
            "HID 1710:8812"
        ],
        "disk": [],
        "gpio": [
            "gpiochip0",
            "gpiochip100"
        ],
        "audio": {
            "0": {
                "name": "bcm2835 - bcm2835 ALSA",
                "type": "ALSA",
                "devices": {
                    "0": "digital audio playback",
                    "1": "digital audio playback"
                }
            }
        }
    }
}

I used the serial paths as the PATH_TO_DEVICE in the config.

hopefully that will work for you.
