30m, long way for anything without wires.

you might just make it with RF but dowt it (way to much interference and not a strong enough signal)
you could possibly cobble together something with an ardunio or 2 but that 30m is still a very long way.
nothing UV is going to work.
or go all out, laser data transmission because, well, fricking laser. use a laser break beam and a bit of code to invert it, so it comes on when a laser hits it rather than when it doesn't.

or, timer switch.

You could try https://www.tlc-direct.co.uk/Main_Index ... index.html I have not used one myself but the stuff from TLC is normally good. I find the ranges quoted for a lot of RF remote controls to be generally very optimistic so you will normally need one which will cover twice the distance you actually need to guarantee it will work.

If your WIFI reaches that far, there are some solutions around.
