A smart thermostat can learn your schedule and respond by adjusting the temperature in your home based on your preferences. They are also accessible by a smart phone, tablet, or computer. Smart thermostats allow you to adjust the temperature in your home or business on-demand from anywhere in the world. When integrated with a compatible home security system, smart thermostats can provide additional flexibility by quickly adjusting temperatures when you are home or away unexpectedly (which would be determined by your home security system status).
