Hello,
Looking for a smart switch ZigBee or ZWave that can turn off/on the bathroom fan and light individually (No dimmer needed). House is USA 1950 build probably no neutral wire in most of the outlets.
Please see the picture attached of the wiring.
1 Black wire- Hot
1 Black wire- Turns on/off light if I take it out
2 White wires connected together via a wire nut
