I've been thinking and experimenting with making my home smarter. There is one main rule. When building such systems one thing must be done always. It must work when there is no smart component to that system. For example, if your smart home stops working or startes to glitch, it should still be possible to go to a switch and turn that light on. This can be easily done when building a house or doing renovations. Retrofitting, however, very much depends on way your switches, lights and other related things are wired and installed.
