If your device is showing "offline" this could mean there's an issue with range or configuration. Here's what to try first:
Network repair is a helpful feature that allows you to refresh your mesh network's connections. See the steps below:
- 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 dimmer, 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.
As noted above, wait until you see the "Z-Wave Network Repair finished" message before sending any commands to your RGBW Dimmer. Once repair is completed, try including the device back into your network.
If Network Repair doesn't help, simply try excluding and re-including the RGBW Dimmer. It's possible that the communication route between SmartThings and the device wasn't established correctly the first time. Exclusion can help the hub find the best route to the device.
If you have a Z-Wave signal repeater available, try installing it between the dimmer and hub and then perform Network Repair once more once it's been installed. A Z-Wave signal repeater is any Z-Wave device that doesn't relay on battery power, so a smart plug, switch, relay, or even dedicated repeater. If it's a range issue or an interference issue, the repeater should help the hub stabilize communication with the dimmer.
Another important set-up detail is the material of your switch box. Metal switch boxes, rather than plastic, can shorten range and interrupt Z-Wave signals. If your device is inside a metal box this may be why it keeps going offline. If possible, try adding a Z-Wave signal repeater between the device and hub, or try bringing your hub closer to it to see if it keeps dropping offline.
Lastly, try moving the module closer to your hub, excluding and re-including it from the new location. If communication is stabilized, the previous location was probably out of range.
If you've tried all of the above and are still seeing the same issue, please don't hesitate to reach out!
