You could do the rain thing using a rain sensor as a trigger on the XP8, I would think. That way if it doesn't rain at the house when it was forecast too then it would still water the yard.
I would suggest this also as a more reliable option for very local rain sensing. Most sprinkler systems here have a rain sensor or soil moisture sensor connected to them so it doesn't run during these conditions.
