HDMI CEC integration failure

Configuration
1

Hello,

I am facing the below validation error when I set up the HDMI CEC integration.

My configuration.yaml

hdmi_cec:
  devices:
    TV: 0.0.0.0
    Pi: 1.2.0.0
    Shield: 1.1.0.0
    BlueRay: 1.0.0.0

Error during setup of component hdmi_cec

    import cec
ModuleNotFoundError: No module named 'cec'

I am running Home Assistant core (not supervised) version 0.113.3 on RPi 3B+ with Python 3.8.0
I found similar errors but those dated back a few years, nothing recent.
Hoping for some pointers.

  1. Try restarting 2 times
  2. If it continues, try running python3.8 -m pip install cec

Thanks @KTibow, but that errors out with:

Hmm. It probably tried to do it automatically and failed. Try creating an issue over at cec's page.

I solved it a different way, following this
