ThermoPro TP359 Bluetooth Hygrometer Thermometer, 260FT Wireless Remote Temperature and Humidity Monitor, with Large Backlit LCD, Indoor Room Thermometer and Humidity Gauge, Max Min Records

The house I live in has two problems with humidity. In the summer the humidity inside the house can get up over 85% (there are unground springs right next to the house). In the winter the humidity inside the house can drop under 10%. So I've bought a lot of humidity sensors over the last 8 years, and put them in different rooms around the house. The shortcoming off all the sensors I have bought is that I have to walk around and look at each sensor to read it. So for me, sensors which will send the data to my cellphone is a najor improvement. My cellphone can store that data and show graphs of both temperature and humidity. You can pick from a graph for the last 24 hours, a graph for the last 7 days, or a graph for the past year. I have four different sensors, and all four show up in the app. And the sensors talk directly to your cellphone via bluetooth — there is no shipping the data off to some company's web site and then needing to register with that web site. I expect this is ThermoPro's first attempt at an app for a cellphone, and there are plenty of improvements that could be made to it. And right now it has a bug where *sometimes* the app will crash when you have the app download all the latest data from a sensor. It does download the data and save it correctly, and then maybe 30-40% of the time the app will crash. I have been sending debugging-info to the company, and they say they're looking into the problem. But even after that irritating bug is fixed, I have other ideas for improvements the app. Initially I bought three of these and have been happy with them (except for the app crashing). It then occurred to me that this sensor could also be very useful for another problem at my house. My refrigerator will be working perfectly fine for 8-12 months, and then over the course of maybe two weeks the average temp will go from 40F to 60F, usually without me noticing it. The problem is just that it needs to be defrosted (even though you won't see ice anywhere in it). I have put other sensors in the fridge so I can monitor the temperature, but of course I have to *open* the refrigerator to check those. I also have to remember to keep checking, and after six months of it working perfectly fine I'll get pretty lax about checking. The sensor ends up buried behind food, etc. And before I know it, I'm drinking milk which is nearly room-temperature. So I put one of these sensors in the refrigerator, and I'm very happy to see that the bluetooth signal still makes it to my cellphone, without me needing to open the refrigerator. So I've bought another sensor to do full-time duty at monitoring the inside of the refrigerator. And I expect to buy a few more sensors in the next few months, for other full-time duties. I think the company says you can have up to 10 of them. As to the accuracy of these: As I said earlier I've been buying a variety of inexpensive sensors over the past 8 years. And to be quite honest, I don't trust any of them to be 100% accurate when it comes to humidity. But I still own all those sensors, and these new ThermoPro TP59 Wireless sensors seem to be about as accurate as the other sensors I own from other companies. At least they have been so far. I still doubt they're 100% accurate, but I'll be happy enough as long as they're consistent. By that I mean that if they say the humidity is 34%, then I want to be confident that the humidity is lower than at times when the sensors say the humidity is 40%. Maybe the humidity is really 30% instead of 34%, but at least I can depend that the humidity really is going lower if this sensor claims that it's going lower. I have owned my sensors for just a few weeks now, so I can't really say how reliable they will be over the full range of humidity that happens around my house!

UPDATE: The thermometer was not dead, it just needed new batteries. Still five stars. ORIGINAL REVIEW: I bought this to keep track of the temperature in my office. The building has terribly erratic climate control, so my motivation was to be able to have evidence of the temperature when complaining to Facilities. It has worked well for that purpose. I was looking for some kind of wireless thermometer with a nice display, and this was much cheaper than options by companies such as Govee. ( had two of their thermometers a couple years ago, and they both died a few months after I bought them--so I have chosen to avoid their products from now on. Back to the ThermoPro. The display is clear--a little busy, but easy to read the numbers. You get not only temperature, but relative humidity, as well as the maximum and minimum temperature within the past 24 hours. (Even more evidence to support my complaints.) I highly recommend downloading the ThermoPro app--I use it on Android--to set up alerts, and to get a reading of the data it collects on your phone. It stores something like 2 years worth of data, so you get a lot of detail. Amazon just asked me to review this and I was about to take a picture of it for the review. It has a button to light up the display, and as soon as I pushed it, the display went blank and I can't get it to turn back on. I suspect that the batteries were getting low, since they're the originals (2 AAA's) and I've been using it for several months, and trying to energize the light killed them. I don't have fresh batteries on hand, so I can't test my theory. If it turns out this thing is dead, I'll update the review. However, I have a few other ThermoPro thermometers, one of which died unexpectedly. I contacted the company support and they immediately agreed to send me a replacement, which arrived only a couple of days later. My experience shows that you can trust this company to make it right if you get a defective product, even when you're well past the return period.

Very consistent reading and works very well. The batteries they send with it crapped out after a month of just sitting there with out being touched. Had another analog one that read horribly and it was so dry, but yet it read high moisture. This one is well worth the money and has been very accurate no matter where I move it to. Good product I highly recommend it!

First: Don't trust the URLs in the printed material. They give you 404 errors. Why the manufacturer doesn't use a web server redirect statement to keep the printed material URLs active, I don't know. It shows a lack of respect to the customer! The biggest offender - for me - was the 3 year warranty extension. Yes, if you register you get a 3 year warranty! Yet, the URL to the offer doesn't work, as found in the printed material. Obviously, their web master and marketing group aren't talking and thus fail to do a good job. Fortunately, the engineers (both electronic and software) did a great job on this unit! I keep track of multiple units on multiple devices (phones and tablets). The only downside is lack of FiRE HD TABLET support! Why can't they support the Amazon Fire HD tablet? While I'm into Android phone and tablets, my Son and his husband love the Amazon 10" tablets. Given the Fire OS is basically Android, why they didn't do a Fire OS version is beyond me. This unit worked out so well, I'm looking at the Alexa enable version and an indoor / outdoor model. (Again, if they support Alexa, why can't they support Fire OS)?! UPDATE; I have been using it for 3 months and have two feature requests. I encourage all who agree with me to submit to their support email address your own feature request (one per email). Request 1: Export feature using the CSV file format. While it is nice to have this data on your phone and/or tablet, being able to analyze it using a spreadsheet program would be outstanding! Request 2: Support for Windows and Apple laptops and desktops/workstations that support Bluetooth. Windows and Apple computers have better displays and should also be able to gather and display this informatoon. Yes, again I don't understand the lack of Amazon Fire OS support. Four stars because there is room for important improvement.

Great product and app works well. Helps keep track of household temperatures.

I bought a 2-pack of the TP359 hygrometers/thermometers back in April of this year and have been very pleased with their accuracy, ease of use, and remote monitoring capabilities. I use them in high-humidity (90+%) environments where similar devices I have tried in the past usually fail within a few days or weeks. After 6 months of use, one of the unit’s front touch-control panel and Bluetooth connectivity stopped working even though it continued to accurately measure and display the humidity & temperature levels on the device’s LCD screen. However, I was pleasantly surprised when, after a brief (< 5 min) call to their customer support line, the company arranged to send a replacement unit to me free of charge or other hassles! In today’s age of really poor customer service, ThermoPro is one of the few companies that stands by their products and provides exemplary customer service. The only issue I have with the units is the inclusion of the “CLEAR” button on the front touch-control panel. When handling the unit, it is pretty easy to accidentally hit that button and unintentionally delete the entire history of measurements taken. IMO, the CLEAR button should have been omitted from the front panel and the app updated to provide this functionality instead, or at the very least require the user to confirm their intent before clearing the historical data from the device when the CLEAR button on the front touch-control panel. BTW, I’ve seen other reviewers say they weren’t able to view more than the most recent week of historical data in the app when viewing “1 Year” of data. To do so, all you have to do is swipe from left to right on either of the two graphs (temp or humidity) to see up to a year of older historical data. Whether viewing historical data under the “1 Week” or “1 Year” timeframes, only one week of data can be displayed on the graphs at once; however when viewing in the “1 Year” timeframe, you can use your finger to swipe right to see data older than the most recent week, but you’ll still be limited to seeing a single week’s worth of data on the graphs at any one time. This is understandable given the screen size constraints of mist mobile devices.

It only works when you're at home but it works really well. No more unzipping the tent to check the temperature. Gives The temperature to the 10th of a degree, the humidity by the percentage.But no decimal.

Arrived one day earlier but with two AAA dead batteries!!

Ürünün tasarımı ve verilerin doğruluğu son derece başarılı. Parasının karşılığını veriyor, tavsiye ediyorum

I’ve been using the ThermoPro TP359 to monitor temperature and humidity at home, and it’s been very reliable. The Bluetooth connection to the app works well — I can check current readings and see the history graphs without having to walk to the device. The alerts are useful too when conditions go outside my set range. The sensor seems accurate, and the wireless range (up to 260 ft) gives flexibility to place it where I need. Overall, a solid and practical tool for keeping an eye on indoor climate. Very useful for anyone wanting detailed environmental monitoring.

Excelente producto. Es fácil de configurar, sencillo de usar y la información que muestra resulta realmente útil. Lo compré porque tengo problemas de humedad en una habitación y la ventilación cruzada no ha sido suficiente para resolverlos. Gracias a este aparato me di cuenta de que mi deshumidificador no estaba haciendo un trabajo tan efectivo como yo pensaba. Me ha servido mucho para entender mejor las condiciones reales del espacio y tomar decisiones con base en información, no solo en suposiciones. Además, se ve bien, puede configurarse en español y permite mostrar la temperatura en grados centígrados. Voy a adquirir otros dos.

I have bought two different Models of this thermometer but each gives me different reading in the same exact place.
