I removed a dead (won’t power up) zwave device this morning.
- Using the mobile app, press and hold on the tile for the device. A context menu appears with the “Remove” option.
- The UI will indicate that it wants you to try and exclude the device as part of the removal ('follow manufacturers instructions…"). Just let that timeout (about 60 seconds).
- A “Force delete” option will appear. That will run for 30-45 seconds and then return with a “the device has been removed.”
Since 2020 or so, my ST hubs have had no issues with ghost zwave devices. The force delete has been clean for me when needed.
