No frontend after config Kodi component + (temp?) fix (v0.47.0 on windows)


I’m installing HASS on windows because I need some windows-only-possible integrations with peripheral (io belgian domotics qbus).

All went well during the configuration with builtin components until I implemented the Kodi component. Then I got the error:

And the website frontend did not came up again and there were similar loggings for history, logbook, …
The kodi component made me install jsonrpc-websocket==0.5 and the setting for websockets did not change the error.

I looked at other forum articles and I got the system working with:

  • delete aiohttp folder in homeassisant deps folder
  • install aiohttp==1.3.3
  • install aiohttp_cors=0.5.3
  • pip3 install homeassistant --force-reinstall -I

I do not know if this is a coincidence that I got the system working again but hopefully this can help some smart developers identifying the Root Cause Analysis or users to get their system online again.


I can confirm this behavior. I have to disable the kodi components to get the webui to function. I have not tried the proposed workaround.
