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)
• Explorer Mini T2000
• Explorer IAQ T3950

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
• Remote temperature sensors
• Thermostat alerts (Filter replacement/etc)
• Reading IAQ and CO2 levels (on supported devices, e.g. T3950, only)
• Reading the current schedule state (morning/day/evening/night/inactive)

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
