Hello all!
I have a question regarding connecting a relay to a light switch, and controlling it wirelessly with an Arduino. The relay I have is this one: https://bit.ly/1KhMFKX, I have previously successfully used it to turn remotely turn on/off a smoke machine (only using two contacts for on/off). I have a light switch in the wall that is only a single switch with 2 wires, but in the wall are actually 3 wires connected. I would like to change this switch to a multiway switch, hook it up to the 3 wires through the wall, and between the switch and wire install the NC/Com/NO relay, and also additionally power a wall wart that powers the relay... I'm not 100% sure that I can use diodes this way (and think i actually cannot, but I need to be able to somehow power the wall wart, and there is no other way to do it (batteries are too big, and there is no extra power cable).
This diagram that I can made, is it correct? Incase it is not, could you please elaborate and explain how to properly connect these?
Thank you in advance,
Tommy

Just forgot to mention that I live in the Czech republic, so the circuit is at 230V.
