ThermoPro TP359 Bluetooth Hygrometer Thermometer, 260FT Wireless Remote Temperature and Humidity Monitor, with Large Backlit LCD, Indoor Room Ther...

We use this in our bearded dragon enclosure. I love the mobile app. Easy to read, easy to install.

The fact that it works is advertised aays a lot. I really like the fact that I can just connect to it with the app and pull up reports and look at the fluctuations and temperature in my house over a period of time. Now that I have a couple weeks worth of data I'm going to make some adjustments and see what kind of a difference it makes. A device like this makes it much easier to do that task.

App works well. Provides accurate temperature and humidity levels. Pairs perfectly with Samsung Galaxy Bluetooth. LCD screen is clear and the light is bright.

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!

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 ZeeBooth Fire HD tablet? While I'm into Android phone and tablets, my Son and his husband love the ZeeBooth 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 ZeeBooth Fire OS support. Four stars because there is room for important improvement.
