Dependable and Handy
Fantastic little unit! I put this in my Hoop Coop for my hens this winter to monitor temp and moisture content as to avoid frostbite or breathing issues. I’m so happy with this product!! It works superbly!! It has a pretty good reach for the Bluetooth as well. If you are looking for an accurate and dependable tool for monitoring temp and moisture look no further. This even graphs out all the data for you to be able to monitor your daily and weekly temps. It pairs with your phone and is easy to navigate. It has been consistently below zero here and I just now had to change the batteries in it. I would definitely recommend this product.

Great! Easy to Use and Informative
I LOVE this thing. Simple to use and cheap. The app is easy to install and doesn’t make you sign up for memberships or pay to use it (as of 4/2026). Data tells me exactly what I need to manage my greenhouse temps and humidity. I even have an alert for freeze temps and was able to go out at night and save my starters from damage. Super pleased with the purchase.

Range works as promised
I needed a way to monitor my greenhouse temps and humidity as I get ready for the upcoming growing season. I wanted one that was battery powered and could be read from my house (a fair distance from the greenhouse.) This does what I need as long as I’m in certain areas of my house, which is good enough for me. So far the operating temps are as described, as it recorded overnight lows below 0˚ F a few times.

Excellent value, accurate readings.
Excellent product. I should’ve read the description better because I thought it had a barometer sensor.I have a ThermoPro indoor/outdoor weather station. The station tracks barometric pressure in addition to temperature and humidity to give an estimate of the forecast.This Bluetooth module works great, but again, it only monitors temperature and humidity, not barometric pressure.If they ever offer one with a Baro sensor I would buy it in a second!The app works great and is easy to setup and easy to read the info. Haven’t had it long enough to determine battery life, but it does include batteries that look to be decently made alkaline.You can’t beat the price for what you get, and the app is free as well.I compared the humidity and temp readings to 3 other units known to be accurate and this module was accurate to within .2 degrees on temp and 1% for humidity.Lastly, the item is small and inoffensive to look at, we have it hanging from an outdoor light.

Set Up in One Minute!
This Bluetooth temperature/hyrometer set up in less than a minute, maybe two minutes if you count the time it took to download the app. Batteries are included, and the app is free, with no registration required. Adding the device is as simple as pressing the + sign and selecting the ThermoPro model in the app..I’m using this for an unorthodox purpose and something not covered by the stated usages: I hung this outside on a protected fig (wrapped in a tarp) to see whether the pipe warming cable (also unorthodox) was keeping the area above the critical 20 degrees. Even though this doesn’t state it can be used outdoor, the lowest temperature is listed as -4 F, a temperature that we rarely get in my area of PA.Probably because I’m using this outside and through an exterior wall, the range is not great. I have to be about 12 feet away inside. If I were to use this indoors, as intended, I’m certain the range would be better. Still, this is not a WiFi device. You must be within range to get a reading.The price is right, especially for peace of mind. The gauge seems accurate.

Better Than the Wall Thermostat—Real Data Where It Counts
Title: Better Than the Wall Thermostat—Real Data Where It CountsRating: 5/5 StarsThe Verdict: I use the heck out of this ThermoPro TP351. In fact, I use it so much I often forget where I’ve hung it. Whether it’s monitoring the house or deployed for long-term camping trips, this little sensor has become indispensable.Why It Works:Real-World Accuracy: Don’t trust your wall thermostat. Those units often read the micro-climate of the wall itself, not the room’s actual air. By hanging this in the middle of the room, you get the true ambient temperature and humidity. The difference is night and day.Rugged Simplicity: No screen to crack, no buttons to wear out. It’s small, almost too easy to lose, but that’s the trade-off for a device that just works via Bluetooth.Phenomenal Range: The 260ft spec is conservative. Outdoors in the clear, I get significantly more range. Indoors, I can step outside and still get a solid reading from inside the house.Data Power: With 2-year data logging and export capabilities, this isn’t just a thermometer; it’s a trend analyzer. You can spot humidity spikes or temperature drifts long before they become issues.Bottom Line: This is an excellent purchase and a fantastic value for the dollar. If you need accurate, remote environmental monitoring without the hassle of screens or complex setups, the TP351 delivers. It’s the kind of gear you rely on when the data needs to be right.

Accurate
Amended.I purchased seven total. One stopped working after the fist week. Ironically it wasn’t either of the two outside units. The other was 10* off right out of the box no matter where I put it. All the rest after two weeks have been accurate. That’s two out of seven. At $12.00 each you be the judge.I am very surprised. I purchased three of these and I’m amazed at the accuracy and ease of setup. They all paired easily and accurately. All three synced with one another and the temperature setting on my ac thermostat. I labeled each one; Attic, Living Room and Outside. (I know. They’re designed for indoor use, but I wanted to see for myseif. They’re so inexpensive it won’t break the bank to get a another. Which is exactly what I did.) Then I set the parameters of each one, which was also easy and intuitive. In addition, the range for my intended use is approximately 60 feet max. So far they have all remained paired without any hiccups. I am so impressed I ordered two more immediately. Time will tell but so far, I highly recommend.
