I believe I have read ever post here with M1MAM, and I did not see what I thought to be the number one question answered: does this module accept more than one device? I have been thinking about setting up a zoned HVAC system in my house, and 1-wire really seems to be the best way to go about this. The ideas over at http://diy-zoning.sourceforge.net/ are pretty close, but I don't really see the need for another 24/7 PC when I have my Elk running that can probably do everything I need. Also, does the M1KAM support any pressure modules?
