List of 10 Best Wireless Thermostats in 2021
#10. Honeywell Lyric T6 Pro
Honeywell is a famous thermostat brand, and the Lyric T6 is currently its most popular product in the Pro Series line. It’s a strong competitor to well-known smart thermostats like the Nest 3rd Gen and ecobee while being more affordable.
The TH6220WF2006 model specifically supports traditional HVAC systems, so it’s compatible with most homes. You can also connect to it with either an Android or Apple device. It has three program options: 7 (every day is the same), 5-2 (weekdays and weekends differ), and 5-1-1 (weekend days vary).
You can also opt for the thermostat to learn on its own. Just use the thermostat usually, and it will swiftly learn your routine like when you turn it off while leaving or sleeping, and when you turn it on. Again, you can still manually override these settings.
The thermostat is also compatible with other smart home devices like Apple HomeKit, Alexa, and Amazon Home. And with a 5-year warranty, you end up getting the complete package. Definitely could be considered the best smart thermostat for traditional homes.
#9. Honeywell Home 5-2 Program Thermostat
The Honeywell RTH6360 series is the ideal home thermostat, with its 5-2 programmable mode (weekdays and weekends). You can set up this device with different settings for the weekends and weekdays, which is especially great for significantly reducing power bills and costs.
Another great feature is the thermostat’s Smart Response Learning. This inbuilt program allows the device to learn your ideal usage times and temperature values so that it produces the precise settings you’d enjoy while minimizing the overall power usage. If the settings aren’t to your liking, you can switch to Manual mode and set it yourself.
The device setup is effortless, with a well-detailed guide. The manual might be confusing for some, but that shouldn’t be an issue with Honeywell’s customer service. Once installed, the interface is reasonably easy to use, with a backlit display and some easy program modes. Just set it to Auto, and you won’t have to worry about the rest.
#8. Orbit 83521 Wireless Thermostat
Deviating from the Honeywell line, we review the Orbit 83521 programmable thermostat. Unlike a lot of other smart thermostats out there, this device is relatively simple to use. That’s because its interface is user-friendly so that even in manual mode, you get the right settings.
The device has a backlit display which large visible buttons for setup. It uses 7-day programming so you can manage each day separately according to your preference. Its modes include four programming periods. You can even copy and paste different plans and settings from one day to the next, making planning a lot easier.
If you need a quick change, you can override the settings and a temperature change that will stay fixed without ruining your already set schedule. What’s great is the thermostat is one-stage, meaning it works with all HVAC systems, including different furnaces, ACs, water systems, and pumps.
The only drawback with the thermostat is that it won’t work with baseboard heaters or multi-stage systems. It also has no memory backup, so power outages can cause the device to reset. Other than that, though, for a one-stage setup, this is the best wireless thermostat.
#7. Honeywell wi-fi Thermostat 9000
Another great programmable thermostat by Honeywell is the Thermostat 9000, also known as the TH9320WF5003 model. This device comes packed with tons of functions that can make your home smart and affordable with ease.
The first notable feature is the adjustable programs, which can be manual or automatic. With each, you get different settings for each day, with the 7-day programming in place. With that, you won’t have to worry about leaving the AC on as the thermostat automatically turns HVAC systems off when you’re not home, saving on energy and bills.
Another fantastic feature is the wi-fi remote access, with which you can control the device wirelessly from wherever you choose. The Honeywell TH9320WF5003’s display is similar to that of the RTH9580WF. It has a fully functional colored touchscreen that can lock for security and can be changed to suit your home style.
The one drawback though, is that this thermostat is not the easiest to install. You’re better off hiring a professional. But its five-year warranty more than makes up for this setback.
#6. ecobee SmartThermostat
The ecobee SmartThermostat stands out as one of the most technologically innovative smart thermostats on the market. Its sleek, stylish matte black design goes well in a contemporary home setting, and its interface is also compatible with most smart home hubs.

The screen can also lock just like the ecobee for security purposes, so using it in commercial locations is safe and secure. Like all other wireless smart thermostats, it comes with intelligent learning to adapt to your temperature preferences so that you get the best schedules, plans, and settings.
It does come with its fair share of flaws though. The wi-fi disconnects plenty of times, and the frequent alarms alerting you to the fact can get annoying.
The installation has its issues, like HVAC systems lagging behind settings changes, and turning off your wi-fi or data when connecting your phone to the device. That said, at a price, it’s available at, you’re still getting a load of smart features that are worth it.
#4. Emerson Sensi ST75
The Emerson Sensi ST55 is a unique add-in to our list because Emerson isn’t the most popular thermostat brand out there, especially its wi-fi products. But the ST75 still manages to compete with other high-end products.
