Light control using normal light switch and remote

Hello. I want to control my lights using Arduino. Im sure that I can use a relay to connect 230V light with arduino and control it via remote or anything but my problem is that I want to use remote and normal switch inside wall in the same time. Perhaps some of you tried something like this already and know how to do it? I'll be thankfull for any clues

Perhaps some of you tried something like this already and know how to do it?

It's relatively common. Kitchens and hallways often have switches in multiple locations that control the same (set of) light(s). Replacing a normal switch with the kind used for dual control is relatively simple. Using a relay for the other switch is simple. Your homeowners insurance might have issues with you making this change, though. A licensed electrician could.

You need a 3-way switch. And the relay must be double throw.

If you have to ask someone how to connect it you probably should have someone else do it.

if u use relay and 3way switch, remember that ur relay, when switching on the light, will have a considerable power consumption.
