Product review (3 stars): Unreliable - chooses when to connect.
I was hoping for something that would be reliable and easy. I don't need a lot of features. Temp and humidity/pressure is great. When this thing works it's fine but that's in between apparently losing the signal for a while. I thought it was batteries and replaced them a couple times in both the unit and the sensor - no dice.

If the reliability was here, it would be a 5. Mechanicam hygrometer with a wired sensor you stick through a window like dad used to do I guess is the only way to go.
