Connecting Lutron and sonoff

Continuing the discussion from Easy way to add manual switch to Sonoff Basic (with status toggle) without flashing?:

Sorry to resurrect an old thread.

I am trying to connect Lutron to sonoff.

In essence when the Lutron line goes on I want it to turn on the sonoff switch. This is just a trigger for all other lights in the room that cannot be connected as the wiring in the room is already complete.

The last method described I believe when the gpio Line is pulsed turns the relay on and off. So far so good. My question is does the EWeLink app recognise the change in state or is is simply local to the device.

Thank you.

Can you specify your setup and what you want to do?
What device is from Lutron?
How’s everything connected and why the button from sonoff doesn’t work for you?
There’s always a more hassle free solution than jumping to soldering and playing with mains
