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

Great for baby
This is very basic. I have it in the baby’s nursery to keep an eye on temperature.The update speed is very sufficient, and information is readily available.Easy to read, size is great and goes anywhere.Accuracy is hard to test but i have seen humidity going up on the right times, i. e. Bath time etc..value is great, and tome will tell how durable this is.Bluetooth connectivity is pretty good, i could stay connected at 20 feet i the other room with 2 doors in between, and im sure it goes a lot further.

Accurate
Amended.I purchased seven total. One stopped working after the fist week. Ironically it wasn’t either of the two outside units. The other was 10* off right out of the box no matter where I put it. All the rest after two weeks have been accurate. That’s two out of seven. At $12.00 each you be the judge.I am very surprised. I purchased three of these and I’m amazed at the accuracy and ease of setup. They all paired easily and accurately. All three synced with one another and the temperature setting on my ac thermostat. I labeled each one; Attic, Living Room and Outside. (I know. They’re designed for indoor use, but I wanted to see for myseif. They’re so inexpensive it won’t break the bank to get a another. Which is exactly what I did.) Then I set the parameters of each one, which was also easy and intuitive. In addition, the range for my intended use is approximately 60 feet max. So far they have all remained paired without any hiccups. I am so impressed I ordered two more immediately. Time will tell but so far, I highly recommend.

Very Useful
Seems to work well. App not too difficult to install and use.Instructions a bit weak. When you go to website for clarification there’s a kazillion very similar units. Difficult to identify mine and my exact model was not listed !Had to fish around for something similarNot clear how “history” is accessed and managed; however, very handy/useful feature once figured out.It works to approximate range listed but barely. It receives data in some places in my house – not in others. About 100ft straight line.Overall it seems to do what was advertisedIt does what I wanted it to doModest costI’d buy another one

Works well, sluggish response
If you need to monitor temperatures in a remote, hard-to-access area (like in an attic crawl space) this will do the job. I needed it to adjust my attic fan turn-on temperature.However, it is very slow to respond and needs to be manually updated when you open the app. Not a huge drawback in my case, but if the temperature is more critical to you, I’m sure there are better, more responsive choices.
