Proposed change

Add support for Hue push updates.

Changelog aiohue: https://github.com/home-assistant-libs/aiohue/releases/tag/2.4.0

Push updates are currently limited to lights and groups. There is such a thing as a motion event but I don't have a sensor at home to verify. Motion is now added too.

I've added extensive debug logging to aiohue, so if you have sensors, try enabling debug logging and report your findings here home-assistant-libs/aiohue#49

logger:
  default: info
  logs:
    aiohue: debug
