Which Wi-Fi thermostat is best?
Thermostats are a great way of setting and regulating the temperature at home, but traditional ones don’t always work consistently. If you want something convenient and reliable, a Wi-Fi thermostat is the way to go. You can set the heating or cooling based on a schedule that matches your preference and even control it from your phone. The best device that pairs well with any smart home is the Google Nest 3rd Generation Learning Thermostat.
What to know before you buy a Wi-Fi thermostat
All thermostats can adjust the temperature in a home. But with one that runs on Wi-Fi, you also get the following benefits:
- Remote access: Since they’re connected to the internet, you can remotely access the device and make adjustments to the settings as needed.
- Home and HVAC monitoring: More advanced models can send alerts to your phone if they detect any changes or errors. They can also adjust the temperature automatically, which is handy if you’re not home a lot or don’t have time.
- Precision control: Modern thermostats, including those that run on Wi-Fi, usually have more precise temperature control than traditional ones. Some come with sensors you can install in different rooms to monitor the temperature.
- Cost reduction: Due to the remote access and precision temperature control, these devices can cut down on the electricity bill. If you’re gone longer than planned, you can turn off or adjust the thermostat while out.
- Virtual assistant connection: Many are compatible with virtual assistants, such as Alexa or the Amazon Echo. With these, you can make changes to the device using your voice or a computer, smartphone or tablet.
Each thermostat comes with instructions on how to install it. Usually, this requires you to do the following:
- Check if there’s a C-wire since this is necessary to connect the thermostat to the HVAC system. Most thermostats have five wires, located behind the cover of the device.
- Turn off the HVAC system using the breaker panel.
- Remove the cover and backplate of your old thermostat.
- Connect the new backplate in its stead.
- Reconnect the wires and attach the new faceplate.
- Connect the device to your current internet network.
As with any smart home device, Wi-Fi thermostats can have a few problems, such as:
- Wire incompatibility: Without the right wires, you won’t be able to properly connect the thermostat to the HVAC system.
- Software glitches: Sometimes, the associated software can glitch or display an error when accessing the device remotely. Also, if there’s a power outage, it can cause the device to stop working temporarily.
- Installation: Depending on the setup and how many wires it has, it can be tricky to install a Wi-Fi thermostat. When in doubt, hire a professional to do it for you.
Also, if you have a single-zone heating HVAC system, it can be hard to regulate the heating or cooling throughout the house. This can be an issue if certain rooms in the house are often hotter or colder than others. One solution to this is to use a multi-zoned HVAC system instead since these let you regulate individual rooms better.
What to look for in a quality Wi-Fi thermostat
Modern Wi-Fi thermostats are highly customizable, meaning you can program them to do the following things:
- Control, monitor and regulate the indoor temperature throughout the home or in specific rooms.
- Maximize energy efficiency to cut costs.
- Set an automatic schedule based on when you want the device to be on or off.
- Connect with virtual assistants or other smart devices.
- Monitor changes at home when you’re away.
Most Wi-Fi thermostats come with an app, such as the Nest app, which you can use on a smartphone or tablet. With an app, you can access the device remotely and make quick changes to the schedule or temperature without hassle.
Some thermostats are compatible with different smart home devices, which is convenient if you want to use all your devices at once. Others only work within their brands.
Most Wi-Fi thermostats have a minimalistic design. They’re usually round or square and come in white or black, though some come in other colors, such as pink or blue.
These devices also have a digital screen, often a touchscreen, with an LCD display. If you have a larger thermostat, you can program it directly using the screen. For smaller ones, you might need to connect through an app.
How much you can expect to spend on a Wi-Fi thermostat
A standard one costs $50-$150 and has all the essential features, such as programmable buttons and a touchscreen. More advanced ones cost $150-$300 but can connect with virtual assistants, monitor your home and send important notifications directly to your phone or tablet.
