In recent decades we have seen large advancements in thermostat technology, and even more so in recent years with the addition of WiFi controlled devices. Technology has gone from settable temperatures, to programmable (a huge break through of its time), to the all mighty WiFi Connected Thermostat. Since 2013, these devices have improved even more than the latest generation, saving even more money than any device before. 

WiFi thermostats are best known for drastically reducing homeowners energy costs. This is done through automatically adjusting the temperature depending on whether you are home, asleep, or away, by analyzing your heating and cooling patterns and adjusting for the energy-saving opportunities, and by letting you create temperature zones that can be independently controlled. According to many studies, home owners can save up to $200 annually by installing a WiFi device, which would pay for the device itself in the first year, and then continuously save you money from there on after.
