re: Help wiring 3 way smart switch

The easiest way I had wired one was put it after the last manual switch. It kind of acts as a third switch in line. Set it up to toggle from the manual light switches.
The "hard" part is figuring out how to supply it 120.
edit: Just saw a youtube video saying these don't support 120 as the switch voltage input like the other shellys. You'd still put it after the 2nd manual switch.
Do you have 3 wire romex going to your switches? If you only have 2 wire, I'm not sure this can be done.
With 3 wire, you'd remove the line voltage from the switches and use them as dry contacts to send the switch signal back to the shelly.

I think I can get it done by putting one shelly in each box. As you said I will wire the one which controls these lights after the second switch, and then in the first box I have another circuit that I can use to run the shelly and I will just use it with the first switch to signal the other shelly.
