Editorial Review

Little known fact: Radio Flyer wagons were named a century ago in honor of Guglielmo Marconi, inventor of radiotelegraphy, and Charles Lindbergh, the first man to fly non-stop across the Atlantic. What they had to do with wagons isn't known, but the name sounded cool at the time. Radio Thermostat, the company, was founded 30 years ago and the name has a slightly archaic sound to it. They'd probably be named Bluetooth Thermostat or WiFi Thermostat if they were founded today.

And WiFi thermostats are what they make. The Radio Thermostat is indeed a WiFi thermostat that works with an app on your smartphone. While this concept isn't new -- the Nest line of learning thermostats originated it in 2011 -- the Radio Thermostat does a good job of cloning most of Nest's features and even adding some new ones, such as temperature optimization based on the type of fuel you use to heat your home. As with a number of other WiFi thermostats, it bases its heating patterns on the presence of your smartphone, and therefore their app, in your home. Phones go away, heat goes down. (Your pets may have something to say about this -- and any children too young to have cell phones, if children that young still exist.) In fact, the app has a range of energy-savings program that will reduce your bill, especially if your local government offers incentives for lowering power usage.

The app allows you to set your temperature by day and hour for the full week. It will send out alerts if anything goes wrong in your system. So the Radio Thermostat has very similar functionality to the Nest, even if it doesn't have the same sense of designer style that Google's thermostat brings with it. For some other thermostats that have similar functionality, and often a great deal of style, look at the Honeywell Lyric 2nd Generation, the Schneider Electric Wiser Air and the Zen Thermostat.

CT50 Reviews From Around The Web


This does work well via my wifi connection and phone app. In fact, the phone app is much easier to use than the controls on the thermostat itself.

The real reason I chose this is because of the API. You can connect directly to the thermostat via the API whether you've registered with or not.

This is the second CT50 thermostat I installed. The installation procedure has been improved; however, some technical skill is still necessary.

The Radio CT-50 is a great product for a great price! Installation was easy and setting up was a breeze especially considering the mobile app is easy to use.
