Try to factory reset them and then pair again. They will attach to the same device entry but you may need to set the driver again and reconfigure. Apps will still be attached.
wierd they rejoined jsut fine? seem to be working now (at least events are reporting)
ill keep an eye on it, thank you for the info
EDIT
ahh thats what they were on my C7 before and the I upgraded the FW
To further clarify, this is currently an issue of these devices joining a zigbee 3.0 compliant network. The devices will work correctly if they were migrated from a previous zigbee network running on an older Hubitat hub.
Thats great I was just worried my advice was going to make it worse and you would not be able to pair them again after seeing they were NYCE and I remembered a post about that brand having issues.
