The "Unavailable" error usually points to a connectivity or range issue.
A good place to start is refreshing your mesh network's connections via network repair:
- Open your SmartThings app and locate your SmartThings hub under Devices. Tap the hub to see the device details.
-
Tap the three dots in the upper right hand corner and tap Settings
- Tap Z-Wave Utilities
- Tap Repair Z-Wave Network
- Tap Start Repair
Before sending any commands to your Double Plug, wait until you see the "Z-Wave Network Repair finished" message - this can take up to 15 minutes. Once repair is completed, try including the device back into your network.
If Network Repair doesn't help, try excluding and re-including the Double Plug directly from its installation location. It's possible that the communication route between SmartThings and the plug wasn't established correctly the first time. Exclusion might help the hub find the best route to the device.
If that doesn't help, try installing the Double Plug closer to your hub. This is a good way to see if the issue really is range or if there's a better spot for your strip. Once you've moved the device, remember to exclude and re-include it to give them a chance to connect properly.
If you've tried all of the above and are still seeing the same issue, please don't hesitate to reach out! We'll be happy to help find a solution to the issue.
