synching the 2812 is a pain.
i find the *ONLY* way I can get it all to play, is to take the console outside where everything else is. pull batteries from console, thermo-whazza hub, rain gauge. wait a minute. insert batteries in rain gauge, push reset on wind thing, THEN insert batteries on the thermo-thing, and THEN insert batteries in console. wait a few minutes til the console displays readings. then bring the console back inside, and resync it with the heavyweather junkware (press down arrow for a couple secs til it beeps, and hit resync on heavyweather).
this is really a pain because I have my wind gauge up on a 30' (!) mast, as I live where there are heavy trees and wanted it as high as I could get it so i'd get something resembling wind. I redid my mast mount so it was easier to bring it down for this reset process, we'll see how that goes.
and for bonus points, I had the rain gauge screwed down, so I have to unscrew it to pop its battery from the bottom. wtf bad design is that?!? I'm thinking of running some long thin bolts up through the mounting board, and using wing nuts on top instead.
ps. when you attach the wind gauge to the mounting arm, make sure you push it on firmly enough to snap on completely. once you do so, you won't get it off again without damaging it. if you don't click it on properly, you may find your wind gauge on the ground with a broken wind cup. DAMHIKIJD.
