Customers say

Best temperature sensor!
I love this TP357 temperature sensor. It is so much smaller than I expected though. I’ve had other versions in the past that were larger, so I think I was just expecting those sizes. I actually like how small this is. Seems perfectly efficient to show what it does in the small size. The other models have larger screens that show max and min data if you want that at first glance, but I just go to the app for the history. I also love that it has a magnet on the back in addition to the little kick stand.I used to have the old school versions with no Bluetooth, and would never go back. It’s a game changer to be able to have a real time history of the temperature changes and the Bluetooth connection allows for quick review of all the data in the app. You can also export the data quickly and easily.The reason I love this one over the other new ones with Bluetooth is that it displays the temperature prominently on top and is also a larger font size display than the humidity number below. The TP359 version seems nice enough, but I hate that the humidity is displayed at the top. I constantly have to look twice because I naturally look at the top number expecting temperature. I don’t know anyone that cares more about humidity than temperature. The temperature should always be the number displayed at the top of the display and I hope they update their other models to do this as well.

Very useful, a deal at the price
This is a spectacular deal at the price. You are getting a lot of software for free as well as the measuring device itself. This thing saves me the trouble of entering data into a excel sheet. It will compute MAX/MIN points at any user selected point time span and record up to one year. I notice other reviewers have comments about Bluetooth range but for me I am using an iPad over 60′ and thru one exterior wall and have no issues.They only minor con is that when compared to a NIST calibrated bulb thermometer, it is reading from .5 to 1.0 degree low. I am surprised, considering the considerable software effort they expended on this thing, that they have not included a calibrate adjustment feature.The mfg spec of 3″ square is just flat wrong. I measure the exterior case at: 2-3/8Wx2-1/8Hx3/4D and the screen at: 1-7/7Wx7/8H. This is not an issue for me, but the screen is a rather low contrast LCD and you may have trouble reading it in certain lighting conditions.But at the price this thing is rather amazing and you might want to try one to see if it works for your application. Also the software allows you to monitor several of them, which opens up the possibility of placing them around your house at various points to get a handle on HVAC differentials. In short, this thing is potentially very useful, not something you can say for all such low priced consumer measurement devices. I have a friend with a +$300 Davis Instrument, that isn’t as well done!

Great, inexpensive
I love knowing the indoor temperature and humidity. This inexpensive product does the job! It has both a magnetic back and a stand-up option for versatility. The battery has lasted well over a year.

Functional and good price
Sufficient. Exactly what I needed, good price. I was surprised how small, but still satisfied.

Portable and Accurate
We liked this small digital thermometer enough that we bought a second one. Itâs small and simple, but the temperature and humidity levels appear accurately and itâs easy to put most anywhere. If you donât need a large display or extra bells and whistles, this little guy performs great. Itâs a good value that wonât hurt your pocketbook.

Excellent longlasting product. Stellar cust service.
excellent product. accurate. versatile. durable. longlasting.bluetooth range is great. i can see the temp on my ground floor, sitting in the basement.the temp and humidity alerts are invaluable. the charts and data export features are also very useful.i greatly appreciate that i can use rechargeable AAA batteries in this thermometer, and that it’s not outfitted with that dreaded custom lithium battery that lot of electronics makers use that render their product a one-time use, disposable product.i’ve owned several thermopro thermometers over the last 5 years or so, with previous versions of the tp 357 and also their cooking thermometers. they have all performed flawlessly over this period. no issues at all. i’d give this company 10 stars for product longevity if i could.this product’s excellence is only matched by the company’s stellar customer service. the luxury of being able to speak to a live person in customer service is a rare one these days. but not only do you get to speak to intelligent, informed, technically proficient and friendly customer service people at thermo pro, they are very easy to reach – (no long hold times or complicated automated phone routines). oh btw the company is based in the US, as is the customer service which is a total bonus.in this day and age, its almost impossible to find longlasting, durable products. and to actually have easily accessible, responsive customer service too…. is just icing on the cake.

They work!
I used these as a ‘scientific yet non-scientific’ experiment to see the temp and humidity of an enclosure. They worked great and consistently. The battery worked for about 30 days before needing replacement. The Bluetooth worked through a cast iron enclosure. Super simple. Their app is needed to download and is super intuitive – very easy to set up and use. There is no export to an email I could find so I captured app information my phone screen with a photo. It also tracks the historical temp and humidity. I can’t recall how long it showed the historical information on the app. It does not save it either past the advancing date precursor. I used 3 sensors. One was placed outside near my enclosures to track the outdoor ambient temp and the other 2 inside separate cast iron enclosures. For our experiment, the humidity was the surprise bonus metric to capture!This would work great for a house crawl space! It would be readable from outside the house or from the first floor.

El termómetro e higrómetro son precisos y funcionan a la perfección. Las medidas son exactas y fluctuan adecuadamente conforme a la temperatura y la humedad. El tamaño del termómetro es pequeño, portatil y ligero. Los números son legibles a una distancia relativamente cercana.La aplicación es facil de usar y se empareja con el termómetro en segundos. Las gráficas de temperatura diaria, semanal, y anual son exactas y muy útiles.No tiene luz propia y no se puede leer en la oscuridad. Pero se puede consultar la temperatura a cualquier hora desde tu teléfono.Es el segundo que compro.
