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!

Good price and seems to work fairly well. I like the display, and the app gives you decent options. Mine is in our shed but well within the 260ft range. It has some minor trouble connecting, but in fairness, there are a lot of walls it has to send the signal through. Despite this, it keeps track on its own and when it does connect to the app, it updates it, so no issue with losing data. The magnet is very strong, and the kickstand and wall mount hook/screw hole gives you plenty of options for mounting. Exporting data to email is a nice feature. I wish this one had a wifi option, but for the money, it gives you everything else.

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.

Nice and helpful. I often check to look at the temperature changes in a longer period of time. The ability of storing data for days and weeks are good (probably on to the app) Two things i wish it could design differently 1. I hope the clock is bigger or at least the same size. The truth is most people will need a clock on desktop and the second thing is then a thermometr. Yes this has a clock but too small and easy to overlook. I want to place a clock and this at the same time on my desk. 2. I think it lose past records when replacing battery. I lost some historic record because i forgot to sync the data before taking out old battery. The sync is not automatic i think.

A simple temperature and humidity meter that performs without any fuss. I bought 2x ThermoPros over 3 years ago, and they have not missed a beat. One in the kitchen family room and one in the office. They connect to the computer across a distance of about 20 metres without any problems (and numerous walls) and give a great log of the temperature over various time periods. The single battery lasts a bit over 12 months, maybe 6 weeks longer. The display is nice and large and easily read, while the unit can be mounted, has a built-in stand and a magnetic back. They work :)

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

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

I have climate induced health issues. So always wish to measure indoor Temperature and humidity. Many brands I used out of which Thermopro is the best. Accurate readings and durable hygrometers. I highly recommend this brand.

I have 3 at home and this newer version looks the best.
