Interesting. I haven't traded emails with them in a couple of weeks, but at that time they were very confident in a fix they were testing in the field. I am in no hurry now, my roof has 2+ feet of snow on it and more is falling as we speak. It will probably be two months before I can get up there to access my sensor array. On the bright side, the problem has only occurred in heavy rain so my unit has behaved itself all winter!
