Wyze Thermostat Review: Can a Sub-$139 Device Really Beat Nest?
For years, the smart thermostat market was a duopoly ruled by titans like Nest and Ecobee, with entry prices hovering around $250. Then came Wyze. Known for disrupting the smart home security camera market with impossibly low prices, Wyze applied the same philosophy to climate control. The result is the Wyze Thermostat—a sleek, Wi-Fi-connected device that costs less than a tank of gas.
But in the world of HVAC, “cheap” can often mean “expensive headaches” down the road. Does the Wyze Thermostat cut too many corners? Can it genuinely compete as the best smart thermostat for energy savings on a budget? In this review, we test its installation process, app reliability, and heating accuracy to see if it’s a steal or a stumble.
First Impressions & Design
Unboxing the Wyze Thermostat, you are immediately struck by its simplicity. It doesn’t feel like a cheap plastic toy. It features a matte black finish with a physical dial—a nod to the classic thermostat design that Nest popularized. The display is an IPS screen hidden behind the face, only illuminating when you approach it or touch the dial.
It is distinctly minimalist. While it lacks the premium glass and metal weight of the Ecobee Smart Thermostat Premium review units, it looks significantly more modern than the standard white plastic bricks found in most hallways. The dial rotation is smooth, though it lacks the heavy, damped feel of the Nest Learning Thermostat.

One of the biggest barriers to entry for smart thermostats is the “Common Wire” or C-wire. This wire provides constant 24V power to the thermostat. Without it, many older systems struggle, leading to thermostat low battery symptoms or frequent Wi-Fi disconnections.
Surprisingly for its price, Wyze includes a C-wire adapter (C-Adapter) in the box. This is a massive value add. Competitors like the basic Nest Thermostat often rely on “power stealing,” which can cause issues where the thermostat keeps rebooting if the HVAC system is sensitive. The Wyze adapter installs at your furnace control board, converting a 4-wire system into a 5-wire compatible setup.
The Wyze app offers a step-by-step walkthrough for installation, similar to what you’d find in our guide on how to switch out an hz311 thermostat for an ecobee thermostat. However, the instructions can sometimes be a bit generic. If you have a complex system with a heat pump and auxiliary heat, you need to pay close attention to the wiring labels.
Performance & Smart Features
Once installed, how does it perform?
App Control & Scheduling
The Wyze app is the hub for all Wyze devices. The thermostat interface is clean, allowing you to change temperatures, set schedules, and view usage history. The “Auto-Switch” feature (similar to auto-changeover) allows the system to switch between heating and cooling automatically—a feature often missing in budget units like the early Honeywell T5 review models.
Geofencing
Wyze supports geofencing, meaning it uses your phone’s location to determine if you are home or away. If you leave the radius, it sets the temperature to an eco-friendly mode. For a deeper explanation of this technology, read our article: what is geofencing thermostat. In testing, the geofencing was generally reliable, though it occasionally delayed triggering “Home” mode until we were already in the driveway.
Remote Sensors
Wyze sells separate Room Sensors that pair with the thermostat. This helps balance the temperature in a home with hot or cold spots. If you are struggling with a thermostat not reaching set temperature in an upstairs bedroom, placing a sensor there allows the Wyze to prioritize that room. This puts it in direct competition with the ecobee3 Lite Smart Thermostat review, which also relies on external sensors.
Voice Assistants
It integrates seamlessly with Amazon Alexa and Google Assistant. You can say, “Alexa, set the temperature to 72 degrees,” and the response is instant.
Wyze vs. The Competition
The budget thermostat market is crowded. Here is how Wyze compares to its closest rivals.
Wyze vs. Ecobee
In the Ecobee vs Wyze thermostat battle, Ecobee wins on build quality and Apple HomeKit integration (which Wyze lacks). However, Wyze is often less than half the price. If you don’t use Apple HomeKit, Wyze offers 80% of the functionality for 40% of the cost.
Wyze vs. Govee
Another budget contender is Govee. In our Wyze vs Govee thermostat analysis, Wyze generally offers a better app experience and more reliable firmware updates, whereas Govee focuses heavily on Wi-Fi thermometers rather than central HVAC control.
Wyze vs. Amazon Smart Thermostat
The Amazon Smart Thermostat review shows a device built in partnership with Honeywell. It is Wyze’s stiffest competition. Amazon’s unit integrates deeper with Alexa “Hunches,” but Wyze has a physical dial which many users find more tactile than Amazon’s touch arrows.
| Feature | Wyze Thermostat | Amazon Smart Thermostat | Ecobee3 Lite |
|---|---|---|---|
| Price Tier | Budget ($) | Budget ($) | Mid-Range ($$) |
| Controls | Physical Dial | Touch Screen | Touch Screen |
| C-Wire Adapter | Included | Sold Separately | Included |
| Remote Sensors | Supported (Sold Sep.) | No | Supported (Sold Sep.) |
| HomeKit | No | No | Yes |
Common Issues & Troubleshooting
No device is perfect, especially at this price point.
- Firmware Updates: Wyze pushes frequent updates. Occasionally, an update might cause the device to hang. If your thermostat is clicking but not turning on after an update, a hard reset usually fixes it.
- Heat Pump Wiring: Some users report issues where the thermostat says heat on but no heat comes out. This is almost always a configuration setting in the app regarding the O/B reversing valve. Ensure you select the correct setting for your brand of heat pump (O for most, B for Rheem/Ruud).
- Temperature Variance: If the temperature reading seems off, you can calibrate it in the app settings. Check our guide on how to tell if your thermostat is bad to rule out hardware failure.
Pros & Cons
✅ The Good
- Incredible Value: Feature-rich for under $80.
- C-Wire Adapter Included: Saves you $25-$30 and simplifies install.
- Physical Dial: Much better user experience than cheap touchscreens.
- Remote Sensor Support: Rare for a budget thermostat.
- Simple App: Easy to schedule and control.
❌ The Bad
- No Apple HomeKit: A dealbreaker for Apple-centric smart homes.
- Display: Can be dim in bright rooms; simple interface.
- Plastic Build: Feels lightweight compared to Nest.
- Setup Quirks: Bluetooth pairing can be finicky during initial setup.
Frequently Asked Questions
Does the Wyze Thermostat work without a C-wire?
Yes, but you must use the included C-wire adapter (C-Adapter) which installs at your furnace. It does not work on 2-wire heat-only systems without an external power source.
Does Wyze Thermostat work with Alexa?
Yes, it has full integration with Amazon Alexa and Google Assistant for voice control and routine automation.
Can Wyze Thermostat control a humidifier?
No, the Wyze Thermostat does not have accessory terminals (ACC) to control whole-home humidifiers, dehumidifiers, or ventilators.
Is Wyze better than Nest?
Wyze is better value for money, offering remote sensor support and a C-wire adapter for a fraction of the price. However, Nest offers superior build quality, learning algorithms, and aesthetic appeal. See our Nest vs Ecobee thermostat comparison to see where high-end models differ.
Why is my Wyze thermostat blowing cold air on heat?
This is typically a heat pump configuration issue. You need to adjust the O/B reversing valve setting in the Wyze app installation menu.
Final Verdict: The Best Value in Climate Control
The Wyze Thermostat is a triumph of value engineering. It strips away the unnecessary frills of $250 thermostats—like glass bodies and built-in speakers—and focuses entirely on functionality. It heats, it cools, it schedules, and it connects to the internet reliably.
For homeowners wondering are wifi thermostats worth it, the Wyze makes the answer an easy “yes” because the investment is so low. If you can live without Apple HomeKit and don’t need to control a humidifier, there is almost no reason to spend more. It is, quite simply, the best budget thermostat on the market today.
However, if you want premium materials or advanced AI learning, stick with the Honeywell Home T9 or Ecobee Premium. But for the rest of us? Wyze is the way to go.
