Cheaply Control Your Thermostat with a Smartphone!

The ability to control the temperature of your home from anywhere with an Internet connection sounds expensive, but thanks to advances in technology you can purchase a WiFi connected thermostat for just $99.

The Filtrete 7-Day Touchscreen WiFi enabled thermostat brings the convenience of a programmable thermostat into your house as well as the ability to hook your HVAC system into your WiFi network so that you can control it from your smartphone and computer.


The thermostat is a rebadged version of the Radio Thermostat CT-30, which is the company that makes the apps which allow you to change the temperature from your Android, iPhone, iPad or computer. These apps are available for free, and there are no fees to access your WiFi connected thermostat.

Grab the iPhone and iPad app, or the Android Radio Thermostat app.

According to Home Depot, which sells the thermostat online and in stores, the system is compatible with all home and commercial heating and cooling systems, though at least one review states that the thermostat was not compatible with their system. It is important to note that you need a C-wire to use this system. Unlike your standard thermostat, which uses a battery, the WiFi connection sucks up more power and requires a constant power source.

I am pretty excited to get my hands on a this thermostat and try it out. Now that my thermostat is more than 5 feet away from the bed, I will enjoy being able to adjust the heat or A/C without getting out from under the covers. That’s not to mention the $180 in estimated savings that come from using a programmable thermostat.
