I want to replace the switch for our outside entryway lights with a smart switch. Specifically the Lutron Caseta Wireless Smart switch. Lutron Switch As far as I can tell the pictured switch is the only switch that controls the light. If there is another switch controlling the outside lights it is well hidden. . However, it looks like the switch is a three way switch. Lutron has a video explaining how to wire a three way switch to the new smart switch. Can I follow the Luton instructions for wiring the new switch? Thanks in advance for any help.

 

Looks like the ground is on the back side. The two wires at the right end are the same. They are both connected to the same connection and is the hot. You can twist them together and add a tail to go to the new switch. The single wire by itself is the load wire.

Looks like the switch comes with wire tails so that you won't need to add any.
It also looks like it doesn't need a neutral.

The other side is the ground.

 

I enlarged the picture and saw the green. Thanks for the confirmation.

 

That makes sense. Thank you very much for your help.

 

Quick question. It turns out the wire on the left, the single wire, was the hot and the two wires on the right were the load wires. I used a voltage detector and turned the switch on and off to figure that out. So with the switch off the line on the left was live and the two lines on the right were not. With the switch on all the wires were live and with the circuit breaker tripped all the wires were dead. Apologies for the my poor electrical vocabulary. :-) So, I used a three port push in wire connector to connect the load lines to one wire in the smart switch, another connector to connect the hot to the other wire in the switch and another for the ground wires. Everything seems to be working fine and I just want to make sure I haven't done something that is dangerous by hooking up the two load lines with the push in connector. Thanks

 

Rare to see two load wires but what you did was ok.
I don't think that device is particular to line/load anyway.

 

OK, thanks again. This forum has been a lifesaver.
