I recently upgraded to Hubitat C-8 from C-7. Most things are working fine, except for the Zigbee Yale lock on the front door. This was previously very reliable. Since the C-8 upgrade it is completely unresponsive to remote commands.
Using the new C-8 Zigbee logging there are no logs for the Yale Zigbee showing up when I do lock/unlock commands through Hubitat. The device shows up as OK in the Hubitat Zigbee device list.
Could there be an incompatibility with Yale Zigbee and the new C-8 hardware ?
I have two Yale zigbee locks and with the exception of a problem with an earlier beta firmware release they have been reliable on the C8 post-migration for the last month or so. I'd suggest trying two things.
(1) try rebooting the zigbee radio.
(2) if that doesn't work you might want to try re-pairing them and see if they will reconnect.
