Smart Deadbolt

 About 6 months ago my electronic keypad deadbolt died. A couple of batteries in its battery pack had leaked causing the electronic control to stop working. This left me with a dumb key based lock with a useless keypad. 

I have finally selected a suitable replacement, the Kwikset SmartCode 910. This keypad integrates into smart homes by using the Z-Wave Plus protocol. This hardware was chosen since Kwikset has a proven track record with building quality locks and I have personally seen some of their basic digital locks last at least ten years even when constantly exposed to the weather. 

Since my Home Assistant didn't already have any existing Z-Wave hardware I chose to add a Nortek GoControl USB stick. I chose this Z-Wave radio since it also contains Zigbee radio which could come in handy if I ever choose to migrate from using a physical Raspberry Pi with a RaspBee II to a containerized installation. 

As this was my first foray into Z-Wave, I had to setup both the Z-Wave JS official add-on and add the Z-Wave JS integration. This was pretty straightforward once I realized both were required. To step the add-on, all that needs to be done is generate a random network key that is 16 bytes long and select the device. The GoControl has the Z-Wave hardware as port0 and the Zigbee hardware as port1.

Once the add-on is ready, I simply had to add the  Z-Wave JS integration and select configure form the integrations page. From that page I selected Add Node  to add my new device. Since this is literally a security device it needs to utilize the secure inclusion. Then all that had to be done was pressing the A button which my specific smart lock uses for pairing. 

Finally the new device is visible. Now I just need to figure out what useful automations or notifications I need to setup to make the most of this new device.
