Capture the exact symptom
ReversibleUse the wall switch to verify power and check whether other bulbs on the same bridge are online.
Run the smallest isolation test
ReversibleRestart the bridge/router normally and power-cycle only the affected bulb once using its documented timing.
Correct only the proven cause
ReversibleRe-add the bulb only if discovery fails after the bridge and network are stable; preserve room/scene assignments first.
Verify before changing anything else
