The "Unavailable" error usually points to a connectivity 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 ZEN20 Power Strip, 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 ZEN20 Power Strip. It's possible that the communication route between SmartThings and the strip wasn't established correctly the first time. Exclusion might help the hub find the best route to the device.
Next, try installing the ZEN20 Power Strip 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!
