One of the best advantages of a smart thermostat is its remote access capability. Unlike other models, it allows you to adjust your HVAC’s temperature from your smart device as long as it’s WiFi connected. For example, if you suddenly need to go out, you can easily set it to a warmer temperature via your phone to avoid high energy consumption. Plus, remote access is convenient if you’ve already programmed a schedule in the thermostat. You can remotely turn it on/off when there are changes in your usual routine -- no energy wasted!
