My ZEN78 High Power Relay Shows Offline in Home Assistant

If your ZEN78 High Power Relay is successfully included to your Home Assistant network, but is unresponsive to commands or shows as offline, you may need to try healing the network.

Interferences like large furniture, thick walls, or metal elements can shorten Z-Wave range. The given range for your network is determined by the specific structure of your home and the strength of your mesh network. If you're seeing connectivity issues, we first recommend healing your Home Assistant network. This function refreshes the connections between your hub and devices so that the hub can find the most efficient route to each device.

More Troubleshooting Steps

If your relay is still not connecting after healing the network, give the following tips a try.

Exclude and re-include the relay directly from the target installation location. It's possible the hub hasn't found the most efficient communication route to the devices. Exclusion can help the hub form a better route of communication.
If it's still not connecting, try bringing the relay and the hub closer together to rule out any range issues.
If you had the device connected via the mesh and you have offline issues, try including the device via Z-Wave Long Range if you have a ZWLR supporting hub. Additionally, if you had the device connected via ZWLR and encounter offline issues, we recommend trying out the mesh instead. The beauty of the advent of ZWLR is the option to include each device using the method that works the best.

Factory Reset

If none of the steps above resolve the issue, try a factory reset on the device:

Ensure the unit is powered (the LED indicator will be a slow pulsing red when the device is powered and not included)
Click the Z-Wave button once and immediately after, press and hold the button for 20 seconds. The LED indicator will flash red for 20 seconds and turn solid red for 2 seconds to indicate successful reset.
