Product review (1 stars): Not even close
Sat the outdoor sensor right next to the indoor one. Both read the same temperature. However one said 32% humidity and one said 14% humidity. Hmmmmm.... Real close. Flip a coin? Split the difference? Interpolate? Called their technical support. Was informed that I was 26th in the queue. I will ship back. It will get to Amazon and I will still be on hold. Save yourself time. Get a good old fashioned mercury thermometer and a hygrometer.
