ST motion sensor on the ceiling

Can I install a ST motion sensor in the ceiling, aiming to down, just on the ceiling top over the stairs? To check motion when someone goes up or down stairs and turn on stairs light …thanks !

Yep, absolutely.


I have one doing exactly that. I noticed that the “field of view” is quite wide for the sensor - I had to angle it partly at the wall to stop it activating when somene walked part rather stepped towards the staircase.
