I noticed you are trying to add over 10 battery-powered Zigbee devices without routers (mainly powered like Zigbee lights or signal repeaters like ZBMicro).
And it reached the limitation of the chipset of ZBBridge-P.
You can either:
- Add more router devices to the bridge.
or:
- Pair them to ZBBridge-U, which can hold more end-devices without routers.
Please kindly note: Zigbee tech itself discourages users from building up a network in this way (star-shape). Please add routers to make your Zigbee network more robust and reliable.
