Ok got it back online. Had to move the base unit to a different location. It will be good for a day or so then lose contact again. I replaced the whole rain gauge unit and it still does it. I even moved the transmitter to a different location. It is only the rain gauge, everything else works great. They are all mounted in the same general location. The base is on top of my computer stand less than 75 feet from the transmitter. The base is close to the wifi modem and I think it is part of the problem. I may try and move the wifi modem and get some distance from the weather base.
Man to many wireless things in this house, 2 baby monitors 900 MHz and 2.4 ghz ,cordless phone 2.4 gHz, wifi modem and a print server modem and the weather station . I feel the tumor in my head already!
