Docker: Error during setup of component hdmi_cec

Configuration
1

Hi,

I am using the official HomeAssistant Docker image (0.75.3).

I have just tried adding hdmi_cec to the configuration.yaml with the following lines:

hdmi_cec:

  devices:
    Philips TV: 0.0.0.0
    Bose SoundTouch 300: f.f.f.f

When I restart HomeAssistant, I get the following error traceback:

[homeassistant.setup] Error during setup of component hdmi_cec

During handling of the above exception, another exception occurred:

My hardware is as follows:

Running Pulse Eight USB CEC v1 (HDMI 1.4) firmware version 7 (latest) on /dev/ttyACM1. CEC Utils version 4.02.

Any idea where I could be going wrong? Is something missing from the Docker image?

Thanks,

Hello @danielhitch, did you ever find a resolution to this? I’m facing the exact same problem, also using the latest official HomeAssistant Docker image.

I posit the same question to you, i’m having similar issues in docker getting HDMI-CEC working.
