Product review (3 stars): Not sure of temperature accuracy
Humidity reading seems to be accurate - at least I assume it is because the reading updates fairly quickly when I move the monitor from room to room. I'm not totally sure about the accuracy of the thermometer. The temperature reading is generally very close to the reading on our house thermometer, however, I tried testing the monitor by taking it outside and the reading barely changed. According to my phone, it was 53 degrees outside, but even after staying outside for a few minutes, the monitor reading only went as low as 64 degrees. I had returned the original monitor I purchased because it did the same thing and I figured it was defective. The replacement monitor does the same thing. So either the temperature reading is not very accurate, or the reading takes a REALLY long time to update.
