Xathros Posted July 9, 2012 Posted July 9, 2012 I looked at the IOLincs, but they got horrible reviews. So we tapped into the elevators existing programmable logic controller: http://www.tri-plc.com/t100md1616.htm But of course it requires learning a little different form of logic. It's amazing the stuff you can do with a programmable logic controller, a bunch of relays, triggerlincs, and the ISY-99i. It was so reliable I got my hands on a second controller just to play with. Because the elevator "call button" is the same thing as the elevator cab "floor button", we had to do some logic to determine whether the elevator was picking someone up or was dropping someone off. One thing that was interesting if anyone ever tries it... if you ever try to hardwire multiple triggerlincs to a permanent power source (instead of the AA battery), they cannot be wired in series. They will not properly distribute power evenly. You will probably have to get a 1.5v power supply and hook them up in parallel. Sounds like it was a fun project. I'm glad you got it all working! -Xathros
