Venstar Climate Driver Installation

Climate Icon

The Venstar Driver is Allonis' application that provides a 2 way real time integration with a Venstar thermostat controller within your myServer user interface. It is not reliant on an Internet cloud service. myServer's Venstar driver increases security, decreases response time and increases reliability compared to cloud approaches. The Driver supports more than one monitored thermostat for multi-zone installations.

System Requirements

  • myServer
  • Climate Family App
  • Working Venstar thermostat controlled Heating / Ventilation / Air Conditioning (HVAC) system
  • Venstar WiFi connected to myServer

Before attempting to create a new ColorTouch Thermostat Device in myServer, you should ensure that your thermostat is installed, powered up, and properly configured for use with your HVAC system. Refer to the ColorTouch Owners Manual and Installation Instructions booklet that came with the thermostat. You can also download a PDF version directly from Venstar.

Also, you’ll want to ensure that:

  • the thermostat has been updated with the latest firmware version (the device driver was written against API v4, and has not been tested with earlier versions).
     
  • the SkyPort Wi-Fi Key has been properly installed and configured for use with your Wi-Fi network. It is strongly recommended that you configure your thermostat with a static IP address so that the driver can reliably communicate with it. Make a note of the IP address used, as it is required during the initial device configuration in myServer.
     
  • the “Local API” option is turned on in the thermostat’s “Accessories Menu” (it is OFF by default). If you do not turn on this option, the driver will be unable to communicate with the thermostat.
     
  • The “Skyport Service” option is not required, and may be turned off in the thermostat’s “Accessories Menu” if you don’t wish to use it (it is ON by default). The driver has not been tested with the Skyport Service enabled, but I can see no reason why one would interfere with the other.

Once the thermostat hardware is properly configured, create a new ColorTouch Thermostat Device in myServer's Climate Family as you would any other new Climate Device as shown above.

  • Enter the IP address of your thermostat (or a DNS name that will properly resolve to it). As stated above, it is highly recommended that you assign the thermostat a static IP address. If you allow your router to assign the thermostat an IP address automatically (via DHCP), the address will likely change each time the thermostat and/or the router reboots. If the address changes, the driver will be unable to communicate with the thermostat until you edit the settings above to reflect the new address.
     
  • By default, the driver will periodically poll the thermostat and update the myServer with its current status (recommended).
     
    • Alerts are queried separately from sensors and status, and needn’t be queried as frequently. Again, adjust to suit your tastes. Alerts can also be independently queried via scripting or Actions. As such, you can optionally disable Auto-Refresh Alerts here and query them via Actions or scripting using the timing method and polling interval of your choice. 
  • The ColorTouch Thermostat supports one (and only one) additional, external temperature sensor (Venstar model number ACC-TSEN, sold separately). If you have one connected to this thermostat, choose “Yes” from the “External sensor connected” popup menu. Otherwise, leave it set to “No”, the default.
     
  • In order to properly interpret time-stamped information received from the thermostat, the driver needs to know if your thermostat is configured to be aware of Daylight Saving Time (DST). Your thermostat will be DST-aware only if you have enabled either of the following features via the thermostat’s touchscreen menus:
     
    • The optional Skyport Service, which is ON by default. It will be used to automatically set the date and time on the thermostat, and the thermostat’s “Set Time and Date” menu will be disabled. It will also automatically adjust the thermostat’s time for DST.

    • OR
    • You have specifically enabled the “Daylight Savings Time” setting in the thermostat’s “Set Time and Date” menu.
  • Finally, if you created a 4-digit security PIN code to enable the thermostat’s screen-lock feature, you must enter the same code into the spaces provided, or the thermostat will reject any attempt by the driver to control it (though, it can still be queried for status updates).
