Reliable Cellular and WiFi Temperature Humidity Monitor
Reviewed in the United States on December 18, 2025This WiFi Temperature & Humidity Monitor, setup was easy, and I liked that the two-year subscription was already included. The app is clean and easy to use, and I can check temperature and humidity readings anytime, whether I’m nearby or far away.
The remote temperature sensor works reliably and updates quickly, which makes it great for keeping an eye on different spaces like an RV or a vacation home. I also appreciate the flexibility of getting notifications through the app, email, or voice, it’s nice being able to choose how I’m notified, that way I don’t have to constantly open the app.
Switching between cellular and WiFi has been seamless, and the readings have been consistent and accurate from what I’ve seen. Battery life is excellent, plus is rechargeable so no batteries to buy.
Overall, it’s been a convenient, well-designed monitor that does exactly what I expected and is good that I always know what’s going on with temperature and humidity, no matter where I am. Good value.

I've had this setup in my rv while in storage. Its been running great and reporting temps using cell service, even though its spotty around there.
Buuuut the product has a "give us 5 stars" message so just fyi.

Reviewed in the United States on January 12, 2026
I have been using this temperature/ humidity monitor for a few weeks now. I got it mainly to put in my camper. We are seasonal campers and this is a really neat device to keep tabs on where the temperature and humidity levels are. It is pretty easy to use. You plug the device in and connect and your good to go. It is smaller in size so its easy to find a place for it. I like that I can check on the house even when I am miles away. It gives peace of mind knowing everything is okay. We have a wood burning stove so sometimes the temperature can get warm. This is great to keep tabs without having to walk to the fire each time.
