I got the RMA in for the rain gauge. It seems to work exactly like the old one. Doing some online searching I found a forum with people that have had similar issues. Of course they never post their fix because they don't care about other people. In my opinion however, I think the unit should be smart enough to zero itself out when it stops raining. I called OS up again and I'm getting an RMA for the main console unit. I really hope thats the issue, because this is kinda lame.
