I’ve been tinkering with the Sonoff basic esp8266 devices and they work pretty well for switching lamps etc.
I’ve been looking at the Sonoff 4CH which would let me switch 4 lights.
The issue I have is that there is no easy way to use physical switches on the wall to also switch the relay. I could solder some wires into the physical switches on the sonoff but I’d rather not operate on it too much.
I then found these which look promising… A little more expensive but I do see some input connectors. Can anyone say if this would help me achieve what I’m trying to do and that “Optically Isolated Inputs” could be used to wire in physical switches on the wall to activate the relays?
