If you're having trouble adding your ZEN75 Heavy Duty Switch to Home Assistant, you may need to try exclusion first.

The exclusion process acts as a soft reset and can be done even if you haven't paired the ZEN75 to Home Assistant or another Z-Wave network before.

• However, please note that exclusion before inclusion applies to the 700 series and earlier chip sets. The 800 series devices will not exclude before they have been included; please factory reset the unit instead, then try inclusion again.

Here are the steps for excluding the ZEN75 in Home Assistant: 

1. In Home Assistant: open Settings > Devices and Services > Z-Wave JS > Configure
2. Click on Remove Device
3. Click on Start Exclusion
4. Tap the lower paddle of the switch 3 times very quickly (the LED indicator will start flashing)
5. Home Assistant will confirm that the device was removed, and you should now be able to add it to your system

Once the exclusion process is successfully finalized, try including the device to Home Assistant again. 

Here are some additional troubleshoots if the above did not help: 

• Factory Reset the ZEN75
• Give the exclusion process another try! It's possible the command from the first run wasn't registered correctly. 
  • When excluding more than once, and not receiving confirmation it was removed, try tapping the lower paddle 4-5 times quickly. This can help make sure the commands go through.
• If the LED indicator is responsive to the inclusion/exclusion/reset commands but still not successfully including:
  • Try adding a Z-Wave signal repeater (switch, relay, smart plug, dedicated repeater - any Z-Wave device that doesn't rely on battery power) between the switch and hub. Make sure to heal the network so that the hub recognizes the new device. This can help in case there is an interference or range issue preventing stable communication between the two nodes. 
  • or, if you're running the Z-Wave JS UI and have a ZWLR supporting stick, you can add the device via Z-Wave Long Range.
• Try bringing the hub within direct range of the switch if the switch is located far away from the hub. If you have a hand-held secondary controller, this would be the time to bring it out!
• If your switch has successfully connected but it's not responding to Z-Wave commands, check out these tips for troubleshooting connectivity.
