Cirrus Wireless Thermometer System

The WGTC Cirrus Wireless Thermometer System is an easy way to monitor any HVAC system remotely. Connect up to 60 thermometers to the Cirrus gateway and view your temperature readings from anywhere in the world using an app on your phone.

How it Works

Each thermometer sends a temperature reading to the gateway once per minute via LoRa which is like long-range Bluetooth and the gateway sends the data to the Cloud (hosted by Amazon Web Services) via WiFi.

Our app, Dependable IOT, is available in the Google Play Store. It can be downloaded on Android phones at no charge. With this app, you will be able to see the temperature readings of your thermometers from anywhere in the world. You can also set high and low alarm set points from the app, so a notification will be sent to the home screen of your phone if the temperature gets out of the expected operating range.
