Great for my home
This monitor has been excellent so far and easily earns 5 stars from me. It solves the biggest reliability problem: it uses 4G cellular first, so you still get temperature and humidity alerts even if your local Wi‑Fi or power is down, which is exactly what you want for things like an RV, garage, storage unit, or remote building.Setup is straightforward: insert or activate the included SIM, add the device in the app, set your temperature and humidity thresholds, and you’re done. Once configured, alerts come through quickly by app push, email, and voice call, so it’s hard to miss a serious temperature spike or drop.What I liked:Truly remote monitoring via cellular, with Wi‑Fi as an optional bonus instead of a requirement.App, email, and voice alerts that let you know right away if temperatures or humidity go outside your safe range.Two years of service included, which makes the total cost of ownership very reasonable for a dedicated monitoring device.For monitoring sensitive spaces—pets in an RV, stored items, a server closet, or a greenhouse—this feels like “set it and trust it” gear, which is why I’m comfortable giving it a full 5‑star rating.

Reliable Cellular and WiFi Temperature Humidity Monitor
This 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.

Works great!
I bought 2 of these. One in at work in a greenhouse to monitor the heat since the boiler keeps going out. The other is at a rental house where the guys go back to Mexico in the winter and the gas meter has a history of freezing up. They both work great and the setting of the temp and humidity is great. Only thing i wish is in the app, i wish the notification was able to be adjusted to repeat until you cleared it. Right now it gives me a slight ding once and that’s it. So if it goes off in the middle of the night, i don’t hear it.

Temperature humidity monitor
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.

Nice, a modern designed temperature humidity monitor that works efficiently.
Temperature humidity monitor are niche products nowadays but you won’t realize the advantage of having such a product in the home until you use it and see the real-time values being collected. I have used it for a week now and here is my take. I would highly recommend this product.My 2 cents below:Pros:- It does the job of temperature humidity monitoring very well with all possible metrics to see- Very fancy looks and gives a great aesthetic while in use- Smart products so accessible through mobile apps remotely- 2 year subscription included in the bundle and considering that with competitors, this device almost comes for free- Rechargeable batteries in it and can give backup for 7 days after full charge- Great build quality and feels very premium- Detailed manual with all steps and troubleshooting detailsCons:- None for now

Very Good!
The dual connection is a big advantage. If you don’t have WiFi available, it keeps sending data through 4G without any interruption. The temperature and humidity data are consistent and reliable. The app makes it simple to check real-time conditions, view history, and download reports. I do wish it had a small display for quick local check, but since you can monitor everything on your phone, it’s not a dealbreaker. The app allows you to receive notifications, emails and even voice calls to alert you to temps outside of your set limits. The seller includes a 2-year subscription – bonus! Use it for wherever you need to ensure conditions are stable. Recommend!
