Venstar

The venstar climate platform allows you to control Venstar thermostats from Home Assistant. Venstar thermostats feature a local API that allows for automation without the need for their Skyport cloud service.

Currently supported and tested thermostats:

ColorTouch T7900
ColorTouch T7850 (No Humidity control)

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
Reading and setting the humidity level and limits (T7900 only)
Turning on away preset
Turning on hold mode preset

The following values are supported for the preset_mode state attribute:

none: Enables the scheduling functionality.
temperature: Disables the schedule and holds the set temperature indefinitely.
away: Places the thermostat in away mode

Note - Please ensure that you update your thermostat to the latest firmware. Initially tested on firmware 5.10 and currently VH6.79.

Local API mode needs to be enabled via the thermostat’s Menu > WiFi > Local API Options > Local API - ON
