The new LX Series of residential thermostats offer simple as you want operation for the most basic users along with the new option of adding connectivity through Wi-Fi. When the optional Wi-Fi module is added to the thermostat, users have the ability to use the free Skyport Cloud Services on their mobile devices. The thermostats also have a local API so that they may interface with many of the most popular home automation systems.
