Since Hass 0.103.x Xiaomi and Yeelight not working

Last working version of Hass with my xiaomi gear is 0.102.3

Updating to 103.x or 104.x I get the message that home assistant can’t setup Xiaomi or Yeelight platforms.

I have been using a venv on raspbian buster. Seems like there is a dependency issue with these latest builds but can’t find any documentation on it.
Cheers,
Barry

Solved: need to install the module “netdisco” in the venv - similar to this issue https://github.com/home-assistant/home-assistant/issues/30120
