I want to set up a small blinking light, like a security warning or something but cant find what I am looking for and may just not know the name of what I am looking for. Id like for either an app controlled or a remote switch controlled (the signal would need to go through walls/be controlled from another room) small LED light that goes off on my desk or my wall when someone in the house may need my attention. Doesnt need to make sound as not hearing sounds is the issue at hand.Some of you may empathize, but when I am wearing my headset I cannot hear my wife or dog call for me. I want a method of some kind of signal light my wife can press a button in another room, and I get a light going off in my computer room. via /r/DIY https://ift.tt/2Y0PzlJ
