Thanks. Oddly, mine has been rock solid over the five and a half years I've had it. I'm currently on my third sensor array (this one is the same one as on the WS-2902). The system started as a WS-1400-IP. The first array was destroyed in a hailstorm, the second started giving bad readings after a couple of years, but this one has been going strong for probably 2-1/2 years, except when the wind vane froze solid during the ice storm last month.
I'll try to look at the ObserverIP this evening and do a reset on it.
Thanks again.
