I assume this is 1 - hot, 2 - load, 3 - ?. Again this light is not controlled by anything else just the 1 switch so assume its 3rd black wire is for passthrough/travel to another point ? How would I go about wiring these wires into a Caseta Wireless Switch as I cannot find a wiring diagram that discusses this in Single Pole ?Thanks
