after upgrading eWeLink app to version 3.5.4 a functionality "Enable inching duration" appeared.
Where can we find clear documentation ? What is the behaviour on Sonoff 4CH Pro R2 with onboard inching functionality ?
I partially answered by myself with many trials.
I updated my eWeLink guide (in Italian unfortunately):
yep!. this extenstion very good! thanks for share. u test it, and it work
