Spuds, Did you get your rain sensor working..??? Is it a wired typed, to the external unit..??? The rain sensor should be pretty easy to work out. Basically, its like a switch, and simply closes then opens again, each time the bucket tips. You should be able to set your multimeter to 'ohms' or continuity, and see/test if the switch is closing on each tip. When the bucket sits at rest, you should see no continuity or an open circuit, then just at the point of tipping from one side to the next, hold the bucket there, and you should see zero ohms (or thereabouts), or a short circuit / tone (depending on your meter and how it operates). I bought a second hand rain sensor, and had to replace the little reed switch to get it going. I picked one up from Altronics, but should be easy enough to find.
