Product review (2 stars): Too many issues encountered
Really wanting this weather station and its wireless sensors to work but encountered too many issues.  I bought this weather station with two wireless sensors.  First, one of the sensors could not be set to channel 2 while can be set to any other channel.  Second, the main unit's temperature reading was stuck around the high temp of the day until sometime pass midnight, everyday.  It's stuck such that the second floor's sensor's reading was LOWER than the main unit on the first floor.  I took the outside sensor and placed it next to the main unit; after about 30 minutes, the sensor's temp reading was a few degrees lower than the main unit.  Third, the relative humidity on one of the wireless sensor was stuck on 12% while the main unit, the other wireless sensor and my thermostat's all reported about 45-50%.  One other small complaint is that the AC connector plugging into the main unit should bend 90 degrees.  It's fine if the outlet is on the same side as the AC connector; if not, the connector sticks out a couple of inches with the wire running to the opposite side.  The features are what I wanted but the accuracy claimed is quite questionable.  The whole thing will definitely be sent back, though I'm not sure if I want a replacement or look for something else.
