If your ZEN73 works manually, but shows offline or disconnects from SmartThings, you may need to repair the mesh network!
In the SmartThings app, you'll find a feature called Repair Z-Wave Network. A network repair will help refresh your mesh network's connections and help the hub find the most efficient communication route to the device.
Use the instructions below to refresh your mesh network's connections:
- 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
Once the hub confirms the process is complete with a "Z-Wave Network Repair finished" message you can try to send Z-Wave commands to the switch. The process may take up to 15 minutes depending on the size of your network.
If your Toggle Switch is still disconnecting, try just excluding and re-including the switch. It's possible the communication route between SmartThings and the switch didn't configure correctly the first time. Exclusion might help the hub find the best route to the device.
If you're able to, try installing the switch in a switch box closer to your hub, or bringing the hub closer to the switch. It's not the most convenient option, but it's a good way to see if the issue really is range. Once you've moved either the switch or your SmartThings hub, remember to exclude and re-include the switch to refresh the connection.
Another thing to check is the material of your switch box. Metal switch boxes, rather than plastic, can shorten range and make connectivity unreliable. Even though the ZEN73 uses the latest 700 series Z-Wave chip, metal is pretty effective at disrupting Z-Wave signals, so if your device is inside a metal box this may be why it shows Unavailable or keeps going offline. If possible, try installing a Z-Wave repeater between the switch and the hub. Any non-battery powered Z-Wave device (like a Z-Wave plug) will extend the signal for you but Z-Wave Plus devices will be almost twice as effective as the older generation products.
If none of the above helps the issue, let us know! We're always happy to help.
