Zigbee bulbs question

Hi all, maybe a dumb question but I can’t find an answer……
Do zigbee bulbs need the switch to be in the ‘on’ position all the time in order to function?
I know that ‘smart’ bulbs do, but wondered if zigbee works the same.

Yes, the switch needs to be left in the on position. I use this to cover the original switch and control the zigbee light.

Thanks for that, really appreciate it :grinning:
