The ZAC38 Range Extender will soon be officially integrated with the new ZWaveJS integration of Home Assistant, so you won't have access to the advanced settings until the integration is finalized. We would recommend updating to the JS integration in order for the ZAC38 to be recognized correctly once integrated. 

Here are the steps to add the device to your system: 

1. Plug the ZAC38 into your desired outlet.
2. In Home Assistant: open Configuration > Integrations > Z-Wave JS > Configure.
3. Click on Add node.
4. Click on Start Inclusion to initiate pairing.
5. While the system is in inclusion mode, press the Z-Wave button 3 times very quickly (The LED indicator will start flashing green to confirm inclusion mode and turn green for 2 seconds once inclusion is completed.)
6. Home Assistant will confirm a successful inclusion

* If you’re using an S2 hub, it will ask you to enter the DSK PIN or scan the QR code printed on the plug.

If you have any issues with including the device, you'll want to try exclusion first. This is simply a hub-based Z-Wave reset for the device.
