## Procedure
### If a Z-Wave light device is in malfunction or offline

2. Verify the device is within range of the Z-Wave network. Try moving the light device closer to the panel, if possible.

Trigger the light device by turning it on and off manually.
If the device is still in malfunction or offline, contact your service provider.
