Issues with Multi Gang Switches (2 Gang / 3 Gang)
**What issue do you have? Please be as thorough and explicit as possible.**
My living room Lights and Fan and hooked up to a single 3 Gang Switch Sonoff. 
The problem is, by default it creates 4 switches; Light 1, Light 2, Fan & All (Control all channel ON/OFF). 
Every time I asked Siri to switch off the Living Room, it will never switch off all channels due to the existence of All Channel ON/OFF existed. It glitched. It will switch off Light 1, Light 2, Fan, and then randomly another channel will be ON again.
