Garage Door Inching Switch

 I want to get a 1 channel inching switch to interface with the my garage door opener.  I could simply take the two low voltage wires from the button on the wall and run them into the Sonoff.  Question is, I was to keep the physical wall button in the loop so dont have to use ewelink only to operate the door. Just not sure if the Sonoff will be able to tell the door was opened/closed via the physical button.

You can integrate the 1 channel inching switch with IFTTT and Stringify if you install a window door sensor that works with Stringify. 

Run "Garage Open" (my flow) flow in Stringify testing the sensor first to see if the door is already open. If it is open then stop the flow, if its closed then place a call to IFTTT to activate the 1 channel inching switch

And vice versa for closing the door.

Thomas, I experienced this with the 4Ch Pro in two conditions:

  1. I had wrapped the AC power cord for the 4Ch Pro around a ceiling beam multiple times, covering the cable that connects the wired wall switch; when I unwrapped the power cord, the wall switch was powered and working again.
  2. When I inadvertantly put the channel/switch I was using in self-locking mode (instead of inching mode), that channel/switch would stay on until I "manually" (via eWeLink) turned off the switch. While the switch is in the "on" status, power to the wired wall switch is killed. Can't explain why. Not an electrician. But changing to inching mode with a .5 second on/off interval rendered the problem a non-issue. The switch automatically turns back off, thus restoring power to the wired wall switch. 

Question for you guys when I try and hook my relay up to my garage door motor on the same terminals as my wired In wall button it kills power to my wired wall switch. Does anyone know why or a fix for this?
If you had the limit switch, and could write some sort of script then maybe a "Close" script would be to push the button briefly if the door isn't closed, then repeat again after say 60 seconds if door is still not closed.  The door might go up and down a couple of times but once closed it should stay closed.


Sonoff won't be able to determine if the door is open or closed.  The only sure way would be a limit switch at each end of the travel.  This would probably be the case even if you just had the Sonoff without a separate manual push button.  To explain, our door responds to the button push in different ways depending on the context.   Door fully open - button press causes door to fully close.  If the door's fully closed, a button press causes it to fully open.  However pressing the button while the door's in motion makes the door stop at whatever position it's reached.   Pressing again causes travel to be reversed.

Really for Sonoff control you'd want an operator with separate Open and Close inputs.
