Review: Fantastic little device for tracking temperature and humidity in your greenhouse. - I was kind of skeptical this would work given the price but it is amazing. It tracks the temperature and humidity in my greenhouse. I can check it from inside the house. It has allowed me to fine tune the heating in my greenhouse by monitoring temperature fluctuations over the course of the day. It is easy to use, was relatively easy to connect to my iPad (I suggest doing the initial set up with your phone, tablet or computer in close proximity. After that you should be able to check it from a distance.) The signal can’t be accessed from the front of my house (which would require the signal to pass thru a wooden greenhouse wall, an external porch wall and an interior house wall that is tiled) but if I move within about 20 feet in my house, it will update with no problem. For the price and functionality, I am very happy. It’s been running for about a month and has used less than 1/2 the battery, which given that it continuously tracks temperature and humidity, seems pretty good. It sits on a shelf in my greenhouse but also has a way to hang it from a nail or hook.
Review: Great monitor, worth the purchase! - This is a great option if you need to check your blood pressure as I was requested to do by my doctor. I test every morning and it seems to be working as desired. I love the Bluetooth connection to the phone app so it keeps the history and data I will be able to show during my next appointment. Quality seems good and so far it is working for quite some time on the first set of batteries.

### ⭐⭐⭐⭐⭐ Excellent longlasting product. Stellar cust service.
*by R***S on May 26, 2025*

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.
