Several ZigBee Devices stopped responding (Troubleshoot question)

[JDRoberts]

The bulbs should be acting as repeaters for each other, at least while they are on power. But they probably won’t be acting as repeaters for the motion sensors, or at least not all the time. Zigbee Bulbs are really weird.

FAQ: Are Smart Bulbs Repeaters? (Updated 2019: the new answer is yes, but may be inconsistent)

Hue Bridge Lightbulbs connected to a hue bridge are repeaters–but only for other devices attached to the same bridge. They essentially form their own mini network. So they won’t help with nearby sensors. Zwave bulbs Zwave lightbulbs like those from Linear and aeotec typically are repeaters – – but only for Z wave. These can actually be very useful in some specific use cases like getting zwave signal down basement stairs or across a garage. zigbee bulbs connected directly to the ST hub Zigbee lightbulbs like hue or Osram if connected directly to the SmartThings hub without using a bridge shift from the ZLL profile to the ZHA profile and then do typically act as repeaters for other ZHA devices. Or if they are Zigbee 3.0 devices, they will connect to the smartthing…
