Enabling Z-wave controller in home assistant

Connect the USB controller to the home assistant server. The device will show up under devices. Select ‘Configure’ and let HA generate the required keys. The device will now be available in HA.

Installing the Dimmer 2 device

Turn of the power at the breakers. Open up the switch box and double check for live wires with a voltage meter.
Take note of where the live/switch wire is connected to the lighting switch and remove them from the switch.

Prepare the Dimmer 2 by wiring it as in the image below and connect to the light/switch:

  • Bridge N and Sx using a short length of wire (only if you don’t have an N wire in the box)
  • Connect the live wire from the breaker to L (right most terminal)
  • Connect the wire running to the light to the left most terminal
  • With a new length of wire connect N to the light switch where the switching wire was connected
  • With a new length of wire connect L to the light switch where the live wire was connected

Once connected turn on the power at the breaker. The Dimmer will run through its calibration steps and the light will increase/decrease in brightness and turn on/of a number of times. Once done press the ‘b’ button on the dimmer 3 times in quick succession to start pairing it with the Z-wave controller.

The Dimmer will automatically pair with the Z-wave network and will be visible in HA under devices. Set the device up as you would any other device in HA.
