If you are unable to include your ZEN12 Motion Dimmer to Home Assistant, start by excluding the device.
The dimmer can be excluded from Home Assistant even if it has never been successfully included; exclusion simply acts as a soft reset to help with any configuration or inclusion issues.
If Home Assistant is having trouble recognizing the device:
-
In Home Assistant: open Settings > Devices and Services > Z-Wave JS > Configure
-
Click on Remove Device
-
Click on Start Exclusion
-
Click the main button 3 times; all the LED's will blink magenta. The LED's will turn solid green for 2 seconds when excluded successfully and the LED's will be solid red for 2 seconds if exclusion fails.
-
Home Assistant will confirm that the device was removed, and you should now be able to add it to your system.
If exclusion does not allow for inclusion, or if you are unable to exclude the device, please try a factory reset on the unit before attempting inclusion again.
SmartStart and Z-Wave Long Range Inclusion Troubleshooting
If exclusion is not successful, if you have previously added this device to your hub, if SmartStart failed, or if the device will not include, please follow the steps below in order. Removing the device from the provisioning list generally resolves most inclusion issues:
1. Check if the device is in the provisioning list:
- Settings:

- Devices & Services:

- Z-Wave:

- Configure Cogwheel:

- Provisioned Devices:

- Trash Icon (identify device by the DSK number):

- Unprovision:

The device has now been removed from the provisioning list.
2. Factory reset the ZEN12. After a successful reset, the device will disappear from the device list.
3. Turn off the breaker to cut the power for the ZEN12. DO NOT SKIP THIS STEP.
4. Go through the inclusion steps listed here to include the device (remember, power stays OFF until step 6).
If that didn't work, here are some troubleshoots we find helpful:
-
Try the exclusion process again in case the command from the first run weren't registered correctly.
-
Try bringing device closer to the hub to see if it connects in a closer location. If it connects without issue in the new spot, then the first location may be out of range or there may be too many interferences in that area.
