Sometimes there are multiple light wires in one switch box. Then a tail can be used or both can be put on the common screw, depends on the local code and/or if it was followed.

I’ll second the motion NOT to use the quick push-in connectors. It’s asking for trouble down the line. Quick way to get your 3-way wires right: the hot feed wire will always go to a common (differently colored) switch screw. The common screw on the other switch will always feed the light(s).

Notice how the two terminals are brass? Those are travelers. You'll save yourself a world of confusion if you get a 5-color pack of electrical tape and mark the traveler wires yellow. Every 3-way switch circuit is different. Colors are totally inconsistent in 3-way switches, the next one you see might have red and white travelers. It's not unusual to ...

In your photo the the round holes you've circled at the top are the backstabs for the travelers for the switch. They're quick connection terminals that are known to be unreliable. You want to shepherd hook the wire and hook it around the brass screw terminals and tighten the screws. It's a good idea to tape the travelers with some yellow tape for future ...

My wiring was fine. The smart switch was defective. Replaced it with a new one and it’s working.

It's very common for people to snatch one of those diagrams off the Web, and say their wiring is exactly like that. Probably not "exactly". The first task is to identify the travelers. Wire colors in 3-way circuits can be anything. Each of the old 3-way switches will have 2 brass screws and 1 black screw. I strongly recommend color-coding in situations ...

You would wire up the smart 3-way switch as shown in the picture below. I am showing the connectivity and did not show the various wire nuts that will be required to connect the wires on the switch to the existing wires in the box. You cannot install the smart 3-way switch in the box at the right because there is no neutral there.

When you reinstalled the new outlet did you break the metal tab? If not both halves are hot all the time. Normally one half is switched RED and the other half BLACK is always hot in your situation. The electrician used the RED wire switched for the light at the outlet. By not breaking the tab, you are back feeding power to the switch (ON THE RED) from the ...

Looking at the 3 way switch in the photo, the black is the hot (common terminal) on the switch and the white and red are the traveler wires between both switches. And on the diagram for the junction box,15 and 11 looks like the two 3 way switches controlling the outlets on the red wire (switched) and the black feeds the hot side (hot all the time). These ...

Yes, a smart 3-way switch can be installed.I have used this 3-way switch in the past. Additionally, with the new smart switches, in general, the use for 3-way IMHO is becoming obsolete. Most link to your smart home hub (i.e. Alexa Echo or Google Home) and you simply have to tell it to turn on or off. If you don't want a 3-way you could also get this ...

Assuming the rocker on this switch doesn't say ON and OFF, this is most likely the middle switch in a "4-way" arrangement. This is when three or more switches control a light. The switches on the "end" of this setup will be the three-way switches you are used to. The one(s) in the middle will be 4 way switches with 4 screws. Rather than connecting ...

Not enough wires. You would need 12/2 from source to first light, 12/3 from first light to first switch, 12/4 from first switch to second light, and 12/3 from second light to second switch. But this is not the best practical way to add a second light to the original circuit. Originally, if I'm not mistaken, you had 12/2 from the source to the light, 12/...
