The one to avoid

This sensor turns up in the search results but has problems serious enough that we'd keep looking.

✕ Avoid

Thermote

Thermote Wireless Remote Temperature Sensor. WiFi Thermometer Temperature Monitor. 24/7 Text/email alerts. Monitoring and History. Water/Dust Proof. No Subscription/Monthly Fees. Made in USA.

4.0 95 reviews · $138.00

At $138 it's one of the priciest sensors we found, and its five bullets are a few words each with no specs.

Why we'd skip it

The bullets are five short phrases, like "Quick Setup" and "Unlimited Users."
No accuracy, battery life, or power source is given in the bullets.
Humidity isn't mentioned anywhere in the title or bullets.

See the listing on Amazon (so you recognize it)

Buyer's guide

How accurate are these sensors?

Most smart sensors are within about 1°F and 3 to 5% relative humidity, which is fine for rooms, nurseries, and basements. For fridges, freezers, or reptile tanks, pick one with a probe or a stated tighter accuracy, and check it against a reference thermometer once.

What can I automate with one?

Turn on a fan or dehumidifier when humidity climbs, get an alert when a freezer warms up or pipes risk freezing, or let a smart thermostat average temperatures across rooms.

How long do the batteries last?

Most battery sensors on these lists are rated for one to three years, depending on how often they report. Low-power radios like Zigbee, Z-Wave, and Thread last much longer than Wi-Fi.
