I've got a single motion sensor, and all light bulbs in the house done with IKEA's TRADFRI bulbs, all bought nearly a year ago. The stack is a zigbee USB stick, Zigbee2MQTT, mosquitto and HA.

The lights are decent, I've had 2 fail so far, but both were on the same spot so I suspect something's wrong there.

The motion sensor has been pretty reliable, still working with no signs of failure. Delays or "dropped" events (the light not turning on) have been very rare and most likely a result of the ancient server I have than the motion sensor itself.

Heads up: you can bind two ZigBee devices directly. So a sensor can trigger a light without requiring a hub to even be on. It can even work across the mesh network.
