Just curious, is it possible to program the pins so that it triggers by wireless or satellite command? With that scale I don't think wireless is possible though.

the pager is already wireless. So adding functionality to trigger wirelessly (over the phone network) is trivial. And it can trigger only with a special message.

Yeah you are probably right. I'm an electronics newbie and don't know exactly how pagers work in wireless. I'm going to read some material on it.
