Review on 🌡️ 2-Pack Humidity Gauge: Max Indoor Thermometer Hygrometer for Accurate Temperature and Humidity Monitoring in Bed Room, Pet Reptile, Plant, Greenhouse, Basement, Humidor, Guitar by John Bourgeois

I bought it mainly to keep an eye on the humidity in my house. I already have a thermostat that shows me the temperature that controls my heat pump. I've had them for about a week now. The temperature readings on both agree to within about 0.5 degrees, but both show about 4 degrees above the actual temperature in my house, according to the other two thermostats. That's a pretty big difference. The humidity level between the two sensors differs by about 1 degree from each other, but seems to accurately reflect the humidity level my humidifier is set to during the winter. They will only be read accurately if left in one place. When you start moving with them, the temperature and humidity will fluctuate every second in the same way that the temperature and humidity inside a house don't change. I haven't decided yet whether to keep them or return them in hopes of finding something more specific. I should point out that the magnets recline very easily and will likely need to be glued on if you want them to stay in place. It appears that only one magnet is permanently attached in the shaft of the four.
