Product review (4 stars): Slow Remote Sensor
The outdoor sensor is really slow. It must not transmit to often. It takes forever for the outside reading to get to the actual temperature. When and if it does stabilize, it is off by at least 2-4+ degrees. The indoor temp is very accurate. But no tenths of a degree. Humidity readings are pretty close for indoors and outdoors. I own a lot of thermometers. The most accurate is a wired probe for outdoor temp that does tenths of a degree. They show live readings with no delay.
Do not expose the remote sensor to rain. It should be mounted in a shaded area where it won't get wet from rain. I had this sensor mounted where I thought the rain would not get to it. I was wrong. It got wet from a hard rain today and stopped transmitting. Took it inside and dried it out. It came back to life. Even the manual says to mount dry shady area at least 6ft off the ground.
I will probably return it. I already got one of these to replace it and it surprisingly accurate within .08 - 1.0 degrees. It has a big colorful very large backlit display. The outdoor sensor reacts fast.
