My outdoor temperature has never seemed accurate. Now that it's winter, I'm sure it's not 65 degrees outside even though it's snowing. I replaced the batteries in the sensor with no change. I purchased a new sensor and even standing three feet from the station, it will not stay connected. I've used all three channels (ABC) and reset the base unit. It initially shows full bars on the strength of connection, but with a few minutes goes to zero. The outdoor temperature never reflects the actual temperature.
