that is pretty cool! let's say I wanted to do something similar with a light switch (which controls the light) and have it switchable via web at any time and have the light switch on overrides the web setting and has it on.

so basically, ON if either web or physical switch is on. web-switch : physical switch = output 0 : 0. = 0 0 : 1 = 1 1 : 0 = 1 1 : 0 = 1

let,s say I wanted to also/instead add the ability to trigger the light VIA time without relying on network? (in case of unreliable network) . basically I am interesting in making an alarm clock that triggers my bed room light even if the light switch is off, what are some parts and ideas I can look up if I am interested in doing this?
