Practical and efficient, this thermostat from Sensei is a great value for your money. Thanks to innovative features like geofencing, it gives you the ability to customize the temperature throughout your home. It is also user-friendly, making it a solid option for novices.

The one negative with this thermostat is that it runs through Emerson’s cloud servers, which can be unreliable at times; as such, sometimes the thermostat will read as being offline, and you may not be able to adjust the temperature for a short period.

The one negative with using this thermostat is that it is not compatible with heating systems that use electric baseboards; if you have that style of system, this is not the thermostat for you.

Wi-Fi Thermostat Basics

Of all the smart devices I’ve invested in, my Wi-Fi thermostat is by far my favorite; and it will be yours too once you see all it can do. These thermostats are the ultimate in convenience, allowing you to control the temperature in your home using the device itself, voice command or a smartphone app. Using a Wi-Fi connection, you can communicate with your thermostat and keep your home or office the perfect temp.

Most are compatible with smart hubs like the Amazon Echo or Samsung SmartThings, and some let you adjust the temperature in individual rooms, eliminating damp spots and helping you discover and fix any drafts. Plus, many allow you to set up timers and schedules, helping you to keep your house at the right temperature and save you money.

Feeling a little chilly? Just tell Alexa to turn the heat up, and you’ll be toasty in no time. Want your house to be nice and cool after you pick the in-laws up from the airport?  Just use your phone to turn the temperature down 30 minutes before you get there. The ability to change the temperature from home, work, or halfway across the world is a convenience worth any price; lucky for you, these devices won’t break the bank.

 

What to Consider Before You Buy

While these devices are pretty simple to install and use there are several things you need to consider before buying one, or you may wind up paying for something that doesn’t fit with your home. Here’s what to look at:

  • Installation: The first thing to consider is how easy or hard the installation is. For instance, can the device be installed by you or do you need a professional? Can you use your existing wiring? Is there more than one way to configure it? These questions are paramount to figuring out which device to buy, as the degree of difficulty should match your abilities. Hiring an electrician can cost money, but if you’re not handy and the install looks complicated, you may not want to risk ruining the device or causing a short.
  • Compatibility: Many Wi-Fi thermostats are compatible with most heating/cooling systems, but make sure your thermostat works with what you already have and how it is set up. Some people have separate thermostats for upstairs and downstairs, which may require you to buy 2 devices or need to rewire your existing system, so understand what you have and what you’ll need.
  • Smart Pairings: Most of these thermostats work with other smart devices and hubs, so check to see what smart brands your thermostat pairs with. You don’t want to buy an Android-based device if everything else you own runs through Apple or get a model that doesn’t work with Alexa if that’s what you’re currently using.
  • Usage: Are you looking for general temperature control or do you need spot heating and cooling? How you plan to use the thermostat will determine the model you pick. For example, if your kid’s room is always chilly, you may want a device with sensors to maintain a warmer temperature in that area only.

I hope our guide to the Best Wi-Fi Thermostats has helped you understand why owning one of these devices is such a good idea. While the Sensei is our top pick and is a great value, the other 4 models are equally impressive and work well in any home. These thermostats are efficient and convenient, keeping you cool in the summer and toasty in the winter- all without having to get out of bed, or even be home!

Whichever you choose, you can rest easy knowing you have bought a quality device that will make your life easier.
