In my master bedroom I currently have a Lutron Maestro switch that controls both my ceiling fan and lights. The switch can dim the lights and alter the speed of the fan. I would like to switch this setup to two independent switches - one to control the lights (dimmer) and one to control the fan (on/off). The switches I want to get are wifi enabled, so they require a neutral and can be grounded. I would like to ground them. I did this change in the room next door and it went well, but the wiring is a little complicated.
When I opened up the box to my current switch, I see 4 Romex cables coming in.
Cable 1: 14/3 romex. The red wire is connected to the switch. The neutral and ground and capped together with the other neutrals. The black is capped off by itself.
Cable 2: 12/2 romex. Black, white, and neutral capped with all others in box.
Cable 3: 12/2 romex. Black, white, and neutral capped with all others in box.
Cable 4: 12/3 romex. Black and red capped with other blacks. Neutral and ground capped with all others in box.
Here is a diagram of the existing setup: Diagram
The black wire from the 14/3 romex is not hot when I turn on the breaker and test it with a no contact voltage tester.
Is it possible to convert this setup to two individual switches in a 2-gang box? In the room next door with similar wiring, I transitioned this to this and everything is working.
