Lennox Home

The Lennox Smart Thermostat App allows you to remotely access and control your Lennox S40/L40 Smart Thermostat and advanced accessories from anywhere in the world. Whether it’s adjusting your home’s temperature or schedule, monitoring your indoor air quality or balancing room temperatures, the control is all at your fingertips.

You must own a Lennox Smart Thermostat (S40/L40) to use this app. The Lennox Smart Thermostat must also be connected to your home’s Wi-Fi router before the app can control the settings. For more information go to https://www.lennoxsmartertogether.com/help/index.html
