Review on Thermometer Temperature Humidity Hygrometer Assistant by Robert Hardin

So far so good, but a bit difficult to read from a distance as the font is small. If you're having trouble switching the unit from Fahrenheit back to Celsius, make sure your Smart Life app is up to date. Then go to the humidifier settings ("Set”) in Smart Life. Select "Fahrenheit" and then click on the pencil icon in the top right corner. Scroll down and click Test Device Network. You may get an error message, but that's okay. I've done this a few times, then exited and reopened the app. After that, the settings stayed the same.
