Product review (1 stars): bad wireless readings
Really not worth it.  I had both units inside the house next to each other,,, both the temp & humidity was off by maybe 1 or 2.. degrees or percent of humidity.  I can live with that.  I am not forecasting weather for a living... just want to keep an eye of basic temp & humidity throughout the house.  I intended to place the wireless sensor in my crawl space.  I have both hot and cold water pipes running through the crawl space so keeping an eye on the temperature is a good idea.  imagine my surprise when it was 13 degrees out the remote sensor indicated 60 degrees in the crawl space.  i thought a vent had broken and I was trying to heat the entire neighborhood.  Nope... it seems no matter what the temp is the sensor will never read below 58 degrees... most times indicating 60,,,  so really it is totally unless..
