electricalwiring
Newbie here from India.
I was wondering if a Sonoff Basic switch can be connected as given in the diagram below:
The "Light Switch on the Wall" stays always in the 'On' position. And the Sonoff switch disrupts the flow of electricity.
Disclaimer: I am not an electrician. I will be getting this connected by a qualified electrician.
Edit: Changed the diagram to better reflect how a switch works
I was only able to get it to work with two companion switches. The Lutron series does not work properly with two occupancy sensors. My goal was to get the apt on top and the entry way to have the lights turn on when the tenant or person entering opens the door.
I like the lutron; works really well and turns on only when needed if its truly dark.
This is how its the four way with companions would be wired

See the diagram and the description for 4-way.

If you accidentally broke the tab between the black (common) screws on the swtich, simply use two short pigtails off the supply line like this...
If you have two separate cables (one to the fan, and one to the light), then you'd wire it up like this...
And again if you've clipped the tab between the terminals, it will look like this...
Here is what the original circuit would have looked like with 3 wire cable...
And here is what the original circuit would have looked like with two separate cables...
Don't forget, since it's a bathroom the receptacle has to be protected by a ground-fault circuit interrupter (GFCI).

There's no reason that wouldn't work unless the manufacturer advises against it. It's a possibility that frequent on/off cycling isn't good for it, but that's unlikely. It's somewhat likely that there will be a wifi reconnect lag, however, so take that into consideration.
Really, this is no different than a typical motion detector on a switch loop.
