Zigbee Pairing Issues with Keen Smart Vent

Greetings everyone! I’m reaching out for some guidance on a Zigbee pairing issue I’ve been struggling with. Hopefully, someone here has encountered something similar and can shed some light.

I recently had a Keen Smart Vent that stopped working properly. After some troubleshooting, I decided to delete it from my system and reset it to factory defaults. The goal was to start fresh and re-pair it with my Raspberry Pi 4 setup running openHAB 4.1.1. Unfortunately, despite numerous attempts, the device won’t re-join the network.

I’ve tried everything from rebooting the system to manually scanning for the device. The debug logs indicate some activity when the device is in pairing mode, but nothing concrete. For instance, I see entries like:

2024-11-10 09:14:57.797 [INFO ] [bee.discovery.ZigBeeDiscoveryService] - 0022A3000011CF86: Starting ZigBee device discovery

But no successful connection follows. I’ve also tried a factory reset on the device and ensuring the firmware is up to date. Still, no luck.

Does anyone have any tips or tricks for resolving persistent Zigbee pairing issues? I’m comfortable reading code, but I’m not sure where to start looking in the logs. Any advice would be greatly appreciated!
