Aleary,
If you have not bought a home automation controller for your PI, I suggest that you invest in the Norket HUSBZB-1. This is a USB Zwave & Zigbee controller. I am running this USB stick on a PI 3 and I am able to controller Z wave and Zigbee devices in HA. You can get it from Amazon: https://www.amazon.com/GoControl-Linear-HUSBZB-1/dp/B01GJ826F8
As a heads up, the ZHA (Zigbee) component is fairly new and does support all types of Zigbee devices. However, it does support lights and binary sensors. For more information about the ZHA compoment please visit the following links below.
