I have a hue bulb used in a lamp without the Hue hub, just direct to ST. Works fine most of time. I have a smartapp, Smart lighting, used to switch on at 8pm, off at 11:30pm.
It comes on fine, however something is switching it off at 9:45pm and I can’t see what in my routines or smartapps etc.
If I switch it back on, it then stays on and switches off at the correct time.
Is there anyway I can see why?
