I made a modification to one of my Sonoff's See the pictures above.
This allows me to have a momentary push button wired to the Sonoff to turn it off/on or pair a remote control to it. The push button can be some distance away from the Sonoff
The reason I did this is because I intend to install the sonoff in the roof space of my house connected to a light circuit. I will then run the low voltage wire to my push button light switch on the wall of the room.
I can then activate the lights by either the wall switch, the 433mHz remote, or my phone.
It would be good if this was a standard feature of the Sonoff. It only requires installation of a terminal block connector socket and some openings made in the casing.
Hi arik ng.
Can you explain me how can I install a sonoff wi-fi in my current electrical system ?
Example : I have a Bulb light with 2 switches (these are deviators, right). I can Install sonoff so everything is working together?
from what you say it would be enough to go in Sonoff's settings ..... did I understand well?
p.s : from your screenshoot I don't understand nothing !!
How is it possible for the sonoff shut down the light bulb if I turn on the light on by wall diverter (or by wall switch) ?
Can you explain me the electric diagram ( between light bulb-sonoff-wall diverter) to do what you say ?
There is a big problem in your diagram.
If the light is turned off with wall switch, how can I turn it on with sonoff ? Because sonoff take tension from the wall switch in your diagram !! And so we have the same problem !!
Your diagram is ok for 3 of 4 total scenario. But here we talk about make all scenarios workinig !
If accidentally someone turn off the light with wall switch..... we can do nothing !
With the solution posted by @Ian Gough we solve every scenario !!
But if there is some other solution without open and solder the sonoff..... it would be better!
You are right. Your is a good solution without any work to do.
but I think many others have thought of your own solution.
But here we were looking for a solution to solve any kind of scenario.
And welding the two files on the sonoff button we created an external button and then we can use each button of our house!
Maybe the best thig is to ask to Itead to solve this problem via hardware/software. And this is possible because Sonoff have a pin (gpio14) free for this use !!
The data we can input to the scratch are simple, like the integrated button :
wall button on = tension = (HIGH)
wall button off = no tension = (LOW)
Hey Arik, you happen to be from Singapore? According to our population, the chances are quite slim hahahaha... but how thank you for the helpful tip! Just to clarify, this is using the Sonoff Basic? So you install a Sonoff Basic behind every wall switch?
