The much-anticipated Wyze room sensor launches today. Originally pledged in 2021, it’s a small wireless device that pairs with the smart home company’s Smart Wi-Fi thermostat, launched in December 2020. Designed to improve comfort in your home and help manage hot and cold spots, the Wyze room sensor detects temperature moisture and movement. The sensor only works when paired with the thermostat using the Wyze app, so it cannot be used as a standalone temperature monitor.
Each sensor costs $24.99 plus shipping, or $69.99 plus shipping for a three-pack. It can be purchased in a bundle with the Wyze Smart Wi-Fi Thermostat ($70.99) for $145.96 (plus shipping).
Room sensors are a popular addition to a smart thermostat to give you greater control over the temperature in every room in your home. The Ecobee thermostat, the Nest Learning Thermostat, and the Honeywell Home T9 are some consumer models with the option of wireless remote sensors. While they can help your thermostat cool or heat a room to a specific temperature, they can’t target the temperature only in that room. If the room sensor in the kitchen says it’s too cold, the thermostat will send heat to each room in order to make the kitchen warmer.
Wyze room sensors have two main functions: an automatic comfort mode that uses data from the sensors to keep the rooms you’re in at the temperature you want, and a hot/cold spot management system that keeps your entire home in place. constant temperature. This can be set to prioritize energy savings or increased comfort, or somewhere in between.
Auto Comfort mode uses the device’s motion sensor to determine which rooms you’re using and then averages temperature readings between them. It then connects to the thermostat via Bluetooth to tell your heating/cooling system to adjust to that temperature. With the Wyze app, you can turn certain sensors on or off based on what mode the thermostat is in — Sleep or Home — so you don’t inadvertently cool your basement all night because you’ve eaten a midnight snack.
The sensors also feature a temperature equalization (3 to 10 degrees Fahrenheit), which allows for the difference between the thermostat reading and the sensor reading. A lower displacement will provide a more accurate temperature in the room while a higher displacement will give the system more flexibility and is likely to save more power.
The E-ink display on the sensor provides a visual indication of room temperature and humidity, a feature none of the competitors offer. Both the T9 room sensors from Ecobee and Honeywell Home measure humidity, temperature, and motion, as does the Wyze. Nest can measure temperature and only work with the Nest Learning Thermostat, not the newer Nest Thermostat.
Wyze sensors are also notably cheap — sensors from competing companies start at $39.99 compared to $24.99 for Wyze. Each Wyze thermostat can support up to six sensors, the same as the Nest but less than the Honeywell (20) and Ecobee (32). The sensors are powered by two AAA alkaline batteries that Wyze says will last up to three years. Comes with a magnetic stand to place on a shelf or table or can be attached to the wall with double-sided adhesive tape.
The new room sensors are not required for the Wyze Thermostat to function, they are just an additional way to help manage your comfort levels. While we haven’t tested Wyze sensors, based on our experience with other manufacturers’ models, room sensors are most useful if you have areas in your home where your heating or cooling system struggles to keep warm or cool enough.
