Was anyone else in the house at the time that might’ve toggled a switch while you had discovery running? I’ve been able to get older, non-plus, z-wave devices to join to an Edge driver while still also connected with a DTH. When that happens, the DTH version of the device remains fully functional, while the Edge version of the device will send commands to the device but never get updated. The Edge version of the device becomes fully functional if you delete the DTH version through the Groovy IDE. You may also be able to delete the Edge version through the Groovy IDE - I haven’t tried it so I’m not sure.
Do you have the CLI installed on a computer? If so, you can probably track down which device has been added.
- Run
smartthings devicesand pick out this new Zooz device from the list - Run
smartthings devices <device id> -y, replacing<device id>with the number from the device list. You should see the z-wave node ID listed under “zwave: networkId”. - Find that node ID in your device list in the Groovy IDE.
