It is clear how inching works - set a duration and the switch stays on for that duration, flipping to off when the duration passes.
I want to put a (remote) Internet router on a Sonoff switch with “Reverse Inching”, so that when I turn off the switch, it turns back ON after a set time (instead of OFF after a set time). The reason is that once the router is switched off, I have no remote access to the Sonoff switch to turn it back on (well, the Internet connection is cut off because I turned off the router).
This seems to be a simple programming task, once inching is in place (tick box for “reverse” functionality) but I understand there may be a limited demand for the functionality, other than resetting an electrical device.
