ThermoPro Bluetooth Thermometer Hygrometer, 260FT Range Temperature Sensor Greenhouse Thermometer, Remote App Control Temperature and Humidity Monitor with 2-Year Data Logging Export (TP351)

I’ve only been using it for a day so I can’t speak on longevity. So far I LOVE this device. I bought it to monitor my cars interior temperature when I leave my dogs in there. I’m never far away so no issues with the Bluetooth connection range. It is incredibly accurate, down to the tenth of a % and updates quickly. I love that there’s no buttons or controls on the device itself it manes operation very easy through the app. It even came with batteries. It’s the perfect size to throw in the back seat by my dog’s crate when I take them on trip in the summer, or anytime really. I can make sure my car doesn’t get too hot if I have to run to the store. I do dog shows and I prefer keeping my dog in my car when we aren’t showing so they can relax and this gives me such a peace of mind. I will be ordering another to put in my greenhouse. The price of this is more than reasonable for the peace of mind it gives me. I wish I would’ve bought it sooner.

Very accurate! I used it in an incubator to check the thermostat and found it was running cool. I calibrated my incubator based on this and had a 90% hatch rate. It connected to my phone seamlessly with Bluetooth (wifi not an option in my school building). I could also check it with my phone when standing outside near my classroom. I could see the history from the weekend as well. I highly recommend, especially for the price!

While this product works well overall,...it does not work through metal walls of buildings. I thought that it was supposed to, which was why I bought it.It does however join the app when it has signal flawlessly. I like the app and this product, so I will find a proper place for it.

Very useful. Can track a time graph of temperature and humidity. Can buy multiple and rename them, so i can track the temp of specific locations simultaneously. I'm trying to determine the best spot in my house to store temperature sensitive long term food without central AC. Then will test how much an ice pack drops the area temp during a heat wave.

We bought this as a backup to our built in incubator thermometer while incubating chicken eggs. This one was more accurate than the one that was built in so it made sure we kept the temp and humidity right. Had a 95% hatch rate with this. Battery life is amazing we haven’t had to change them at all. Slight variations on humidity but still very accurate.

Bought this to keep one in fridge and one outside camper. Nice to keep an eye on fridge while driving from our phone. Range seems good. App doesn’t require a subscription to use. Only thing to improve on is the notifications on temps outside of the range you set. Have to have app open and active for that to work. Be nice to get notified with it off, I just have wife check on it periodically.

These work great. Left the battery in these last week- still working this week. Range is not the best but Im not trying to remotely monitor it from space so it's good for meAccurate and easy to read. Good price and a good buy for me7

Bought this for my dad because he’s always checking the temperature in his greenhouse. The Bluetooth is nice I just wish it had a little bit farther range. The app is easy to use and it understand. The accuracy is very good and almost spot on with his wall thermometer.
