Perhaps I need to further clarify : I want to use the same brand/type/look of buttons that will be used for all buttons and outlets (BTicino Living). So, these buttons are just standard normally open push buttons. My question is : how do I interface these with PlutoHome. Forget x10 (bulky, old, toylike, expensive for the functionality) or any wireless solution (this house is under construction, so I can opt for cheaper and more reliable hardwired solution). My idea is to use a range of industry standard components that are reliable and cost effective (consider 50-odd buttons). Has anyone interfaced PlutoHome with a digital input system that handles a larger amount of channels like this (like the SeaIO series from sealevel.com) ?
