Card Access sells a Zigbee module to interface with some of the appliance made by Sub-Zero and Wolf. The Zigbee module is connected to the service port to enable wireless communication. Card Access wrote a driver for Control4 and apparently Crestron and Savant can interface directly with the appliances by using a wired connection.
Just wondering if anybody has tried to create a device handler for these appliances? If not, how hard would it be to create one?
