TempPro TempAir Bluetooth Hygrometer Thermometer for Greenhouse Up to 260ft

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.

We've had four of these instruments for over 6 months and just ordered two more. All meet or exceed our expectations and are functioning as specified. The single exception is that the Bluetooth range somewhat shorter than indicated but they're all performing within stated specifications. We have not had to replace any of the AAA batteries that were included. That in conflict with some previous reports of excessive battery consumption. The response to rapid changes in ambient temperature is slow, frequently taking 15 or 20 minutes to correctly report the new conditions. We find Graphs of temperature and humidity provided by the app to be quite useful. It's just a personal preference but we prefer this item to the newer and more expensive TP359 model.

This thermometer and hygrometer works great. I use it to keep track of temperature and humidity in my room. The Bluetooth connection is convenient and makes it easy to check the readings without having to constantly look at the device. The display is clear, setup was simple. Overall, it’s a great little monitor and I would definitely recommend it.

I got this to help keep track of the temperature and humidity in my baby's room, and it's been really helpful. It's easy to set up, and I like being able to check everything from my phone without having to go into the room. The display is clear and easy to read, and the Bluetooth connection has worked well for me. It also keeps a history of the readings, which is nice for seeing how the room changes throughout the day. Overall, it's a simple, reliable monitor that gives me peace of mind knowing my baby's room is comfortable.

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.

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).

Works great and the Bluetooth is awesome. We tore down our 115 year old house and I put the original pine and oak floors in a storage container with a dehumidifier while we built the new house. I could check the history of the humidity in the container and the battery level of this unit without opening the container

These are great to use if you want to capture Temp, and Humidity within your home. I have used these for various projects around the home to find hot or cold spots such as the attic vs the inside of the home and outside. They are very durable and connect easy to an iPhone. Thanks for a great product

funciona correctamente a buen precio

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

The Bluetooth feature is very helpful. It is very accurate. A good product.

I love that it lights up when you tap the logo at the top. All the different data points are really useful, and it's big enough text that it can be read from across the room.
