I'm looking at a way to open a door/drawbridge/other stuff automatically when I approach a place, I don't want a lever, button or remote for it, I want like a sensor we can have at our house and that turn lights on when we go near them, I'm not familiar with all the stuff in this modpack, so far I saw the seer stone from AM2 that can do it, but it require essence which wouldn't be easy to supply cause it wouldn't be at my AM2 base where I want that setup... Any help is greatly appreciated
