T100 Is already recognized, only Is missing the most important property: motion sensor response.
So It Is totally useless. Can be you already get it but It only Is not exposed, can be easy. Please fix the problem and a lot of people will be happy ( me first 
)

I always thought it was already there as I never saw any reports saying otherwise, but apparently that was not the case!
Sometimes developing “blind” is hard, but after seeing a report on it on the issue tracker, I have now created Tapo T100 Motion Sensor motion detection not reporting anymore · Issue #127167 · home-assistant/core · GitHub to add the missing sensor.
