If you add or remove a device that has been added to a Smarthub or other controller before, it is possible that there is still data stored on that device, resulting in the device not being included. You will notice this by the Z-Wave inclusion working to find a device without finding anything.
Reset the device
Use the device manual to find out how to factory reset the device completely before trying to add it to the Smarthub again.
Reset from Smarthub
It is also possible to reset a Z-Wave device by starting exclusion from the app:
- Navigate to "settings 🔧 → devices → remove device → start exclusion"
- Z-Wave exclusion will start
- Perform the same procedure on the device as when you included it. The app will start a countdown from 1 minute while searching for a device to delete.
