Best WiFi Thermostat

A smart thermostat connects to your home Wi-Fi allowing you to check and alter the temperature settings remotely through an app on your phone. These devices are now very popular as you’ll easily find them in most homesteads.

The main reasons why people decide to upgrade to Wi-Fi thermostats are:

  1. The smart thermostats are great energy savers. A thermostat could help you save up to 12% on heating bills and 15% on cooling bills. In a year that could total up to approximately 150 USD
  2. The thermostat can detect when you’re home and away and adjusts to your changes to match your routine
  3. They are also very easy to program – from anywhere. All you need to do is get the app on your phone and then enter the temperature and time settings and you’re good to go.

When schedules change you won’t need to reprogram it

  1. The Wi-Fi thermostat will help you keep tabs on your HVAC system when you’re out of town. This ensures that a breakdown doesn’t happen when you’re away
  2. Lastly, they’re so cool. They can change their color to match your walls, play your favorite music, or display your family’s digital photos

Things To Consider Before Choosing Your Best Wireless Thermostat

There are so many different types of smart thermostats that you could choose from. If you’re considering getting a Wi-Fi thermostat, here’s what you need to put in consideration so that you can choose the right one:

  • The C (common) -Wire requirement

Many Wi-Fi thermostats need a lot more power than a set of batteries can provide. Instead, they rely on low-voltage power from the HVAC system. That’s why they need the c-wire.

  • Ease of installation

Following the step-by-step instructions given by the manufacturer, you should find it very easy to install a thermostat even if you aren’t very handy. The photographs and illustrations should also make things a lot easier for you.

  • Geo-fencing

This makes it possible for you to set up a perimeter around your home beyond which it’s assumed that you don’t need to heat or cool your home anymore. This ensures that the thermostat is not running unnecessarily.

  • Remote access

This allows you to check and change the thermostat’s temperature settings from afar as long as you’re connected to the internet.

  • Sensors

The motion sensors serve a similar function to the geo-fencing feature. They sense whether or not the home is occupied and, therefore, needs climate control. The sensors on the thermostat can cause the display to turn on when someone walks past it – this comes in handy especially at night as it lights up the way for you.

  • Smart home integration

Find a thermostat that you can easily integrate with other smart-home devices and broader smart-home systems.

  • System complexity

If you would like to heat or cool different parts of your home independently, you’ll need a different thermostat for each of these zones. However, it’s possible to control all these thermostats using a single app.

  • User interface

Get a thermostat that displays vital information at a glance and adapts easily to your specific needs.

Professional thermostat installation costs no less than $50. However, if you want to save that money and do the installation all by yourself, here’s how to go about it:

how to connect honeywell wireless thermostat
  1. Before you buy a new thermostat, make sure that it’s compatible with your system. You can check online to see if it’ll work with your wiring.
  2. Shut down your power system at the breaker panel to make sure that no power gets to the old thermostat that you want to replace.
  3. Remove the faceplate and keenly observe how the wires are connected to their terminals.
  4. Remove the backplate from the wall after removing all the wires that are connected to it.
  5. Next, add the c-wire if your system doesn’t already have one. This is what provides power to the Wi-Fi thermostat.
  6. Screw the new thermostat’s backplate onto the wall. Make sure that you pull the wires through before the backplate is securely attached.
  7. Reconnect the wires to their corresponding terminals. Make sure that this is done very carefully.
  8. Install the new thermostat’s faceplate.
  9. Turn on the power to the thermostat and allow the device to boot up
  10. Connect the thermostat to the Wi-Fi, configure it, and link it to the app on your phone. Once you’ve gone through all the prompts, it should now be ready to use

Note: If you experience any kind of problem at any point during the process, consult with a technician. Trying to fix the problem could cost you a lot more than you wanted to save in the first place.

How We Test Wi-Fi Thermostats

Testing a thermostat begins with the installation to be sure that the set-up process was done correctly. This is to ensure that the newly installed thermostat controls the system as it should. When the system responds to the test correctly, that means that the set-up was successful and you’ll be confident that the system is in good shape

If you’re experiencing any problems with your thermostat, here are some basic things to check:

  1. Check the Wi-Fi signal. If the signal isn’t strong enough or keeps fluctuating, then it is not adequate for the smooth running of the thermostat.
  2. Check if the wiring was done correctly and if there are any blown fuses. First, make sure that the power is off then open up the thermostat to make sure that the wires are not touching each other.

If the problem persists, consult with a professional to help you with the troubleshooting process to diagnose the underlying issue/s.

Answer: Absolutely! Wi-Fi thermostats help you save money and they can pay for themselves in as little as one heating and cooling season. It all depends on your climate and energy usage habits.

Final Verdict

Wi-Fi thermostats have been around for quite a while now and the good news is that they keep getting better and better. Some of the newest models in the market use complex algorithms to understand your household’s heating and cooling needs so that they can automatically re-adjust themselves to meet these needs. Also, there are apps through which you can change the settings of the thermostat remotely.

Having tried and tested several smart thermostats, we can confidently say that our best overall is the Ecobee Smart Thermostat with built-in Alexa and room sensor. Although quite pricey, it has the performance and features to back it up.

But then again, all the type of thermostat you get depends on your needs and preferences.
