Hi, I’m currently remodeling my house. The dining room has been wallpapered, and I want to quickly connect the light switch when I notice that the two-way switch no longer works as usual. A Tuya button and changeover switch, how do I get them together if I can no longer get to the junction box.
So I thought about building a circuit that would allow me to do this. That’s basically the electrics.
What do I need:
-
Power supply 220v to 5V,
-
optocoupler 220v to 5V,
-
bistable relay 5V,
4, and a link from the optocoupler , a pulse generator to switch the relay.
I hope someone can help me find the appropriate assembly or component.
Regards
