Can anyone attest to the accuracy of the humidity sensor, ie: have you compared it to an actual hygrometer? I'm just curious because we had a real humidity issue in the house this past summer. We purchased a Santa Fe dehumidifier for the basement which seems to have helped a lot, but I'm interested in hard numbers. Now that the humid weather has gone and the dehumidifier is working I'm seeing humidity levels in the house hovering around 45% which is what we want, assuming that number is accurate.
