12v COB LED Cabinet Backlight with Physical Switch and WiFi Integration

Good day, I would like to make a cabinet backlight based on a COB LED 12v (purchase from ali) with a physical switch and wifi (to make it coupled with each other). I have already done something like this only for 230v light switches, I based it on a sonoff mini smart switch (something like this: Link) i ogólnie działa poprawnie. Szukam teraz takiego przełącznika tylko na 12v (docelowo abym mógł go wrzucić do home assistanta). Najlepiej jakiś najtańszy z ali. Załączam schemat o jaki przełącznik wifi mi chodzi. Coś ktoś doradzi co spełni w.w założenia? .

Hi, the link doesn't work, so it's not clear what you have and it will be hard to help.

Sorry, link corrected.

But what you have is the optimum option, why would you prefer the 12V power supply to run non-stop and only cut off the 12V?

As I wrote above what I have is under the 230v light switches - it works in such a way that I turn on with a physical switch and I can turn off in the app, I can turn on in the app and turn off with a physical switch etc various combinations - the physical switch is coupled with the wifi app.

And now I want to do the same circuit only that for a 12v LED Strip, so I need the same relay under 12v - and this is my question if such a relay even exists because I can not find it.

I could do on a 230v led tape and then use the same relay - everything would work great but as far as I know 230v led tapes are less durable and more problematic than low voltage ones.

But to power a 12V LED strip you plug it into a 230V power supply.

All in all, this makes sense, only the output from the relay should be the terminal device (the light) - and it will still have the 12V power supply on the way and only the light (in this case the led). This won't have any effect on the operation? I have taken the schematic of this relay and added the power supply as it would look like. .

This light bulb marking in this picture is just a symbol for any energy consumer, it could be a 230V bulb, a motor, a TV, a power supply for a computer or laptop or any lighting.

Ok sure, the relay will either switch on the power supply (switch on the led) or cut off (switch off the led), now it seems simple. Thanks for the guidance and help.
