Venstar Thermostat Binding

The Venstar Thermostat binding supports an interface to WiFi enabled ColorTouch and Explorer thermostats manufactured by Venstar.

Venstar WiFi enabled thermostats provide a local API that this binding uses to communicate with the thermostat. This binding does not require "cloud" access and may be used independently of Venstar's Skyport cloud services.

The Local API is not enabled by default, so you will need to set up your thermostat by configuring its WiFi connection and enabling the Local API. In order for the binding to connect, you will need to enable HTTPS support and set a username and password. While it is possible to enable the Local API without HTTPS and authentication, the binding doesn't support it, in an effort to provide as secure an installation as possible.

When you've set the username and password, make a note of these, as you'll need to enter them in the thermostat configuration in openHAB.
