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?

What you want it somewhat difficult to implement. As light switches are currently implemented, they physically close and open the circuit. You will need the light switch to be just another signal, along with the web-switch and timer. Have all of these signals route through a uprocessor, implemented whatever logic you need there, and then use the uprocessor to control the actual light.

You will need a magnetic relay, and you will need to remote the light switch from your main home circuit.
