to use sonoff in parallel with a switch the solution I developed was to solder 2 wires at the sonoff button's terminals and use pulsating switches.
so I can use the sleepof the app and a convetional switch, but tinning in those terminals is very bad and can damage the equipment.
on sonoff basic v3 could put 2 terminals next to the button to facilitate this function
