My old Davis ISS has to be replaced. It is talking to and old Vantage Pro (1) Console.The new ISS is not compatible with the old Vantage Pro, so i'm going to buy a new Vantage Pro 2 as well.... Next thing is that the USB datalogger is not compatible (does it ever stop?)Question... Do I need the data logger to communicatie with WEEWX? (it comes with Wheatherlink software.. which i don't use)
