The ZAC38 Range Extender will be fully integrated with Home Assistant in a coming platform release, so you should have access to all of the advanced settings for the device once integrated.
The ZAC38 is officially integrated with the new ZWaveJS integration of Home Assistant, so you will have access to the advanced settings once integration is complete. If you aren't on the JS integration yet, Home Assistant currently recommends handling Z-Wave devices through the JS integration since all others have essentially been abandoned and / or discontinued and so that the ZAC38 can be recognized correctly.
All About Advanced Settings
The terminology for advanced settings varies depending on your Z-Wave hub; Home Assistant uses the official term “Parameters.” Despite these differences in naming, the purpose remains the same: configuring consistent behavior for your device. We provide the full list of settings available for each device in our Knowledge Base.
Each advanced setting consists of four key parts:
-
Label: If your device is properly integrated with your hub, this will display as the setting's name. Hubs like SmartThings show only the label and description.
-
Parameter Number & Description: Most hubs, such as Hubitat and Home Assistant, list the parameter number along with the label and description.
-
Values: These are the selectable options for each setting. Some are simple (e.g., Enable/Disable), while others use numerical values.
-
Size: This is required in some systems when manually changing advanced settings (e.g., Home Assistant) or in hubs that do not provide direct access to settings.
Accessing the Settings
To access the parameters for the ZAC38 Range Extender:
-
Settings > Devices & Services > Z-Wave.
-
Click on the ZAC38 > under Device Info, click Configure.
Manual Parameter Changes
All of the ZAC38's advanced settings should be available, but if a device is in beta release or had a recent firmware update, it may still need to be integrated for certain settings and parameters. There is another way to make adjustments your device's settings in the meantime.
You can now change any parameter manually on the JS Z-Wave integration for Home Assistant.
-
Follow the steps above to access the parameters.
-
Scroll down below the exposed settings for the device to the Custom Configuration section, where you'll see Parameter, Size, and Value.
-
You can enter the data according to the product documentation and click SET for the parameter to be updated.
