Total Connect Comfort is an iPhone app developed by Resideo Technologies Inc. It falls under the Lifestyle category and is free to use. The app is designed to enable users to remotely monitor and manage their heating and cooling system from anywhere, anytime. It is compatible with Honeywell Home Wi-Fi Thermostats and with Honeywell Home Redlink Comfort Systems when used in conjunction with a Redlink Internet Gateway.

The app offers a range of features that make it easy for users to manage their heating and cooling systems. Users can view and change their schedules, heating and cooling system settings, system fan settings, and humidifier and dehumidifier settings (for thermostats that support this feature). In addition, users can view their indoor and outdoor temperature and humidity levels (when used with an outdoor sensor) and a 5-day weather forecast. They can also access multiple smart thermostats and locations if more than one system is registered.

With Total Connect Comfort, users can view thermostat alerts such as high or low temperature and use the Demo Mode before purchasing a thermostat. The app automatically upgrades to new features once they become available. Whether you're a homeowner or business owner, Total Connect Comfort offers an easy way to manage your heating and cooling system remotely.
