+
+The `venstar` climate platform allows you to control [Venstar](http://www.venstar.com) thermostats from Home Assistant.
+Venstar thermostats feature a local API that allows for automation without the need for a cloud service.
+
+Currently supported and tested thermostats:
+
+- Color Touch T7900
+
+Currently supported functionality:
+- Setting heat/cool temperature when the thermostat is in the appropriate mode.
+- Changing the operation mode of the thermostat (heat/cool/off/auto)
+- Turning the fan on/off
+- Setting the humidity level
+
+Note - Please ensure you update your thermostat to the latest firmware. Currently tested on firmware 5.10.
+
+To set it up, add the following information to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+climate:
+  - platform: venstar
+    host: IP_OR_HOSTNAME_OF_THERMOSTAT
+```
+
+{% configuration %}
