Let’s have a look at what devices can be controlled and connected to Home Assistant with the Z-Wave integration. First you need a Z-Wave hub/controller, in this case an AEON Labs ZW090 Z-Stick Gen5 EU is connected directly via USB into the Raspberry Pi running the Home Assistant software.
To enable Z-Wave within the Home Assistant you’ll need to go to the Integrations section and configure the device.
Configuration -> 
Integrations
To complete the configuration you’ll need the:
- usb_path: most likely /dev/ttyACM0
- network_key: if you want to make use of Z-Wave Plus and the extra security it can provide. Due to the extra bandwidth and battery requirement this is only recommended for certain devices such as locks.
You can generate the network key following the steps included at Home Assistants own documentation they also have a great getting started section with links to many useful resources.
Now Z-Wave compatible devices can be added, managed and removed via the newly enabled Z-Wave configuration panel.
Configuration -> 
Z-Wave
With this guides initial goal of automatic lighting focus will be given on motion sensors and switches. in this case the following specifics will be utilised:
- Fibaro FGMS001-ZW5 Motion Sensor – a motion, temperature and luminance sensor
- Everspring AD142 Plug-in Dimmer Module – a dimmer based pass-through plug socket
These devices have simple pairing functions and can be added via the Z-Wave Configuration panel, with some devices you need to ensure your are registered to receive the sensors outputs through the ‘group associations’. Home Assistant should do this for you automatically, but your experience could differ depending on the controller and devices.
