Yup, this door bell I actually bought from Thailand. I buy this door bell mainly of the brand name and sound i like BUT very unfortunately you guy mentioned this is not suitable for outdoor. If u go to Schneider Malaysia website you may found they sell the weatherproof door bell switch BUT just cannot find this door bell sell in their Malaysia website.

Anyone knows how to modify the two wired door bell to four wired door please share. I was thinking to add step down transformer BUT don't know how to connect the wiring diagram. Appreciate ant sifu can help here.

How about a step down transformer plus a relay? Will it work?

Thanks for your schematic diagram.
As far as I know the 230v AC to 12v AC step down transformer is small enough to keep in the door bell box. BUT how about the AC relay? does it small enough to keep inside the door bell as well. I heard the AC relay need power supply, is it true?
