[ahmed]

I had one of this to my master bedroom shutter it is the standard rectangle shape in Egypt from sonoff brand.
It is wifi connect to rf remote or sonoff mobile apps i need to use one app for everything do you able your kincony mobile app work on sonoff wifi? Or do you have touch button 3 position to shutter/ curtain up and down and stop.
Note each floor has 1 circuit 220 volt to all floor shutters and the current control manual rocker switch beside each curtain, it is mandatory to use wifi switch to connect wireless to mobile apos.
Also please tell me how many of this wifi switches can work with confusion and  interruption because i had 12 shutters
