Proposed firmware change GPIO14

I would like to have a digital input on the Sonoff Basic.  I see a lot of people asking for a good way to interface a simple digital input to turn the device on and off with a switch or other make/break action.

Since GPIO14 is pulled high and exposed on the header this would make the perfect place to implement this feature and it would not affect the standard operation of the unit.  There are alternative firmwares that do this but I would like to use the stock firmware and the eWelink app.

When GPIO14 goes from high to low, turn the relay state on.

When GPIO14 goes from low to high turn the relay state off.

If the relay is already in the specified state, simply leave it alone.

We already have a momentary contact input with the stock push button switch.  This change would give us an input that would work with a toggle switch or a sensor that  provides a continuous high or low state.

In my case I want to use a simple photocell sensor that provides a digital 1 or 0 to switch the Sonoff and have a scene that turns a bunch of outdoor lights on.  In other words use one Sonoff as a master photocell switch.

The sonoff Dual has the function you are looking for, 
you can conect it to a pulse style switch (think dorbell) 
and that way it will work wifi via app, or with the switch,

It would seem like itead would rather sell you a product, with their firmware on it, that is only capable of doing what they want it to do, and then force you to flash the unit with some other firmware to a"Actually get" what you want the item to work as. The Sonoff SV has all the makings of a brilliant device, but it held back by the fact that itead doesn't want to implement a small yet significant firmware change. I will be migrating my entire system and flashing every single unit I have purchased from iTead to something useful, primarily because they are too proud to realize the flaws in their programing, or just too stubborn. Either way, I guess I will be embarking on a learning curve by flashing their crap firmware off all my devices. Quite sad actually, because their ewelink app was relatively decent and hassle free.
