Hygrometer Thermometer for House, Bluetooth Room Indoor Greenhouse Thermometer Monitor Up to 260FT, Backlit Humidity Meter Temperature Sensor with 2-Year Data Export(Previously ThermoPro)

We use the TempPro Bluetooth Hygrometer Thermometer to monitor conditions inside our high tunnel, and it has been a very useful tool for keeping an eye on temperature and humidity without having to constantly walk out there. The Bluetooth connection works well and lets you check conditions from a good distance away. Being able to monitor the tunnel from the house saves time, especially early in the morning or late at night when you’re trying to make sure temperatures stay where they need to be. The display is clear and the backlight makes it easy to read when you’re inside the tunnel. It tracks both humidity and temperature accurately enough for greenhouse use, which is important when you’re managing produce that can be sensitive to swings in humidity. Setup was simple and the app connects quickly. Overall this has been a practical tool for anyone running a greenhouse or high tunnel who wants a convenient way to keep track of environmental conditions.

This is a really nice little thermometer/hygrometer. I'm using this in my basement brewing area to monitor room temperature when fermenting and I also used it to track the temperature of bottles during carbonation and conditioning. It's just big enough and the LCD screen is bright enough that it's easy to read if you're within 10 feet or so. The bluetooth works well and is very easy to connect. I can connect from anywhere in my 1800sf house. The temperature readings correlate well with my high end thermometers. It's been up and running for a few weeks without problems.

This little gadget has been so helpful and cheap. The display has a built in light so you can see in the dark. It’s really small, but works well and is app connected for easy ability to see trends. I used it to monitor temp in my room when our daughter was born. And now I just use it to see if I need to adjust the air conditioning. Definitely would recommend!

Not that it really matters, but when I bought this item, it was branded as ThermoPro. Now it's TemPro. It's the same thermometer/hygrometer being sold now as when I bought it. I really like the orange color and brightness of the backlighting, but it only lights up when you touch the white frame. Of course, if it was always lit up the two AAA batteries would not last nearly as long. I put this in my garage because I like to be able to check from within the house, what temperature the garage is so I can decide whether or not I can comfortably work out there. I'm in Texas and the garage gets very hot in the summer. A nice touch is that it also reads humidity on the display and shows a calculated heat index on the app. After installing the ThermoPro app on my phone, connection via Bluetooth was easy. See my second photo for a screenshot of the app display. It shows the Temperature, the Humidity, the Heat Index and a graphic comfort scale so you can tell at a glance the relative comfort of the heat index by color. I didn't notice before purchasing this because I was looking at a dozen other brands, but this one has Humidity at the top of the display in slightly larger numbers than the Temperature, which is at the bottom. Looking at other brands just now, I see that maybe 80% of them have the Temperature at the top. I understand that humidity is very important to people using these in grow tents, but for my garage, temperature is more important, so I'd rather see Temperature at the top and Humidity at the bottom. Maybe it's nit-picky but, out of habit, when I glance at this I always notice the top number and think of Temperature first because my other digital thermometer is set up that way. So, I'm deducting a star for that. Otherwise, it does what it's meant to do and the app works well and shows the Temperature first! (see my middle photo).

I have a tortoise shed outside and I placed the thermometer inside of it to track the temperature while using heat lamps inside making sure it stayed at optimal temperature. I connected the temp pro to the app and it works perfectly. I can be anywhere in my house and open the app to check on the tortoise house and watch the temperature at all times. Great product.

I used this for Charcuterie making which needs accurate humidity and temperature readings Do not believe the hype for the +/- 2 to 3% on the Relative Humidity (RH) reading or the factory calibration. I performed 2 salt equilibrium calibration checks on the 2 units I purchased. In the ThermoPro T350 unit and or app there is no manual calibration offset adjustment like the Inkbird Temp Hygrometer unit i purchased which you can change the RH offset from its InkBird App. I am very disappointed I didn't learn about the the salt calibration check methode until now. The photo attached shows for the second time I did the 75% salt calibration and the reading for the 2nd time shows a RH of 66% and a high of 68% instead of 75%. The 7 to 9 % difference from the standard 75% is not acceptable. I cannot return it and lost my money. Update: I had ordered a second set of these unit which were renamed from ThemPro to TemPro. The second set of these units I ordered has the same Relative Humidity (RH) problem as the first. After receiving the item and putting them in a calibration test for 2 calibration runs of 24 hours in a salt equalibrium humidity calibratiin environment the 2 units I received more than 48 hours ago failed to achieve a calibrated 75% RH and inducated in both units A reading of 65%. Although both units being the same the are both off by 10% RH. As I stated befire there is no app or manual aRH offset calibration adjustment. As a result the RH adjustment would have to be remembered mentally or written down in a note somewhere. I will be returning these items.

I bought this to keep an eye on the room where rest were most of my guitars. Perth is a bit ridiculous when it comes to humidity and we have bone dry summers and then we get wet Antarctic winters. I've been trying to get a clearer sense of the day-to-day swings so I can avoid my guitar is getting damaged or cracked. The screen on this unit is very bright and easy to read the set up to less than a minute and the Bluetooth app connection worked on the first try. The app gives you a chart of humidity and temperature overtime, which is very useful. I can immediately see when the room dries out and whether I need to bring in a humidifier. I checked this against another hygrometer that I own and they both measure within a couple of percent points so I think the accuracy is pretty good. For guitar storage, especially when you have expensive instruments, you really need to be careful about humidity and I've seen some tragic cases of snapped neck in dry conditions.

Worst product because of showing wrong values in temparature and humidity, showing higher values than present

Works great. Accurate readings and updates quickly.

Nice small screen handy device

Keeps good track of temperature and humidity data. It’s simple and handy on its own. The app is also simple to use and helps track the temp and humidity in graphs that are easy to use and understand. Export feature in the app is also great. If you want to track different rooms you can name the devices in the app. And yes you can switch to Celsius with just 1 button. The only downside is that there appears to be no authentication/security on the Bluetooth connection, so anyone in range could connect to it, but I guess the only risk is maybe your neighbours could find the temp and humidity of your bedroom.
