[REQUEST] Create a modified version with binary sensors

[ahorndesign]

Hi! I need a version of this firmware which allows me to use binary sensors (in my case - tamper switches) with a Sonoff. I am pretty sure this could be done with the GPIO pins, especially for the versions which support temperature and humidity sensors. I might even be able to figure it out myself with some digging, but well-developed option would be much better. Happy to buy the beers it would take.
