To add (include) a non-secure Z-Wave [device](/docs/z-wave/devices/) to your system, go to the [Z-Wave control panel](/docs/z-wave/control-panel/) in the Home Assistant frontend and click the **Add Node** button in the *Z-Wave Network Management* card. This will place the controller in inclusion mode, after which you should activate your device to be included by following the instructions provided with the device. Don't use this for secure devices, since this is likely to limit the features the device supports.

Don't use the OpenZWave control panel (OZWCP), or the physical button on a controller, to add or remove devices. Many devices will only send the information about their capabilities at the time you include them. If you use the OpenZWave control panel, or the button on a device, then Home Assistant won't have that information. Using the physical button on a controller will also result in a non-security inclusion being performed, which may limit the features the device supports.

Security Z-Wave devices require a network key before being added to the network using the **Add Secure Node** button in the Z-Wave Network Management card. You must set the *network_key* configuration variable to use a network key before adding these devices. Some devices only expose their full capabilities when included this way, you should always read the manual for your device to find out the recommended inclusion method.

To remove (exclude) a Z-Wave device from your system, go to the Z-Wave control panel in the Home Assistant frontend and click the **Remove Node** button in the *Z-Wave Network Management* card. This will place the controller in exclusion mode, after which you should activate your device to be excluded by following the instructions provided with the device.
