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.

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.

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.

Accurate, functional value for Humidor
This little gadget is wonderful!! I threw this in my cigar humidor and was pleasantly surprised to find how accurate it was. The app/Bluetooth is seamless and simple; I can easily pull up the app and get a reading within seconds. It feels well-built and doesn't appear to consume battery, so I imagine the AAA's will last a long time. Being that it connects via Bluetooth, you can't check it unless you're within range (260'), but that's anywhere in my house. Allows me to tuck my humidor away and not worry about it. The hygrometer is also a perfect size for my use. Surprisingly affordable and useful item!

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.

Awesome value, Works great, Good fun!!!
Fabulous learning experience: This product has been a joy to own...I've learned so much humidity and temperature in my attic and crawlspace and how the two correlate...way more than any textbook. The price point is a huge value...I hope the company doesn't increase the price. I chose the BlueTooth model because I had grown tired of WIFI connection difficulties with various devices. The BlueTooth connected successfully very easily, and I was up and running in a matter of minutes upon receiving the package. My range isn't 160 ft because the signal is going through two floors and a couple walls, but I can connect anywhere in my house. This product goes beyond my expectations and is one of my all time favorite purchases on Amazon.

Connectivity <<260Ft
A bit disappointed. The item advertises 260Ft of range, but most of the time I can't get it to refresh within 50Ft. It works reliably if I'm in the same room, but that's not the point. Also, this only updates when your phone and the sensor can communicate via bluetooth. So if you're outside the range, no data is available. (I'm not sure how/whether the alarm would function when outside the range.) So if you want a sensor for a room that you will typically be in close (<50Ft) vicinity to, and you can tolerate spotty behavior outside that range, this'll do. But I'll be getting something else for my use case.
