If you are having issues including your ZEN52 Double Relay to Home Assistant, start by excluding the device. The relay can be excluded from Home Assistant even if it has never been successfully included. Exclusion acts as a soft reset to resolve any issues with configuration.

If Home Assistant is having trouble recognizing the device: 

1. In Home Assistant: open Settings > Devices and Services > Z-Wave JS > Configure
2. Click on Remove Device
3. Click on Start Exclusion
4. Click the Z-Wave button 3 times as quickly as possible (the LED indicator will start flashing). Alternatively, if the relay is already installed, you can simply toggle the external switch connected to ZEN52 very quickly from off to on, so: "up-down, up-down, up-down."
5. Home Assistant will confirm that the device was removed, and you should now be able to add it to your system
