At any rate, it might be nice to use something like this because they have at least done the mounting and waterproofing for me. I worry about the heat in my neck of the woods though. Do you think this thing will melt? Or, maybe it would die in some other fashion. The wiring on my roof has to be protected with foil tape to keep the insulation from falling off. Yes, even the teflon insulation goes bad over a couple of years.
It seems to be well made. I'm concerned about the lubrication of the bearings at that temperature. Clear was a dumb color.

The device has temperature, light level, anemometer and wind direction built in. Other functions need to be added on. I have a UV level detector and rain gauge on the roof, humidity and pressure under the eaves. This is utterly painless to add with 1-Wire, would be interested in hearing if it's as straightforward with the RS485 variant.
Adding RS485 accessories will be easy for the hobbiest who can do their own designs. I don't know of any company that makes them for the AAG though. They don't do addressing like standard RS485 so I'll have to design my slaves to use their protocol.
buzzdavidson:
Oh, and AAG's insistence upon NDA for software for this device is utterly ridiculous. This is not exactly a novel application of the components being used, and it really doesn't take a whole lot to reverse engineer the whole device. They should really just release a GPL'ed version of a library that provides basic usage examples and let the community flesh it out.BTW, their Windows-only software for the device is crap. Don't bother.
And for the sake of completeness: The RJ45 wiring for the AAG 1-Wire adapter does not match that used by other vendors. You will probabl fry your other 1-Wire components if you plug them directly into an AAG adapter; I documented a fix for this on my blog: Coming Soon
I think the best thing to do is just re-flash the thing. Hopefully they haven't set the fuses so that can't be accomplished. That would be pretty dumb for them since it would prevent any future firmware updates.
I agree, they should publish the source code with a GPL. Since it's Atmega based, they would have a large community who could program for it and an add-on sensor market would be possible. I don't think they have a business model. Since everything is their own proprietary wiring and protocol, they must think they are going to have accessories for it.
Buzz, it sounds like you've had yours apart. I think mine is held together by two tiny screws but I won't know until I bring it down. I've got it mounted on a section of 2" PVC pipe, my favorite construction material, light and cheap. 
Any hints you have for disassembly would be appreciated.
