Where is the "Remove Failed Node" Option For Z-Wave Devices?

You might have to update state manual as described in the last section here: https://www.home-assistant.io/docs/z-wave/adding/

  1. Go to the States menu under Developer tools in the Home Assistant frontend
  2. Click on the name of the zwave. entity you want to remove
  3. At the top, edit the JSON attributes to replace false with true for “is_failed”: false, so that it reads “is_failed”: true,
  4. Click Set State
  5. Go to the Z-Wave control panel in the Home Assistant frontend
  6. Click the Remove Failed Node button in the Z-Wave Network Management card
  7. The device will now be removed, but that won’t show until you restart Home Assistant
