The accuracy of this is...not great. As you can see, it's at least a degree off of my thermostat on the indoor read (if it was 71.5 - 72.4, the thermostat would read 72, so it's no warmer than 71.4 in reality). I'm going to go ahead and believe the fancy thermostat over this. It also reads hot on the outdoor reading when it's sunny, which...is not a quality build. If you put a UV sensor in something and instruct people to put it in the sun, you have to properly shield the temp probe! It's also consistently a couple tenths off of my old fashioned plastic gauge and a nearby weather station (certified) on rain. If you want to know if you maybe got an inch of rain that week so you can tell if you need to water (one thing I need), or want a general idea what the outdoor weather is before stepping out...this will do the trick. If you're trying to determine if you need to cover sensitive plants (another thing I need), eh...I would cover a few degrees above frost/freeze/hard freeze just to err on the side of safety. I also couldn't get this to reconnect to the satellite information after a few weeks, and no matter what I do with the DST setting, the clock is wrong now that we're in standard time.
