What the heck are these wires in my switch box?

Here is a drawing with the Aeon micro in place at the light fixture. It’s close to the end of the post.

Aeotec Micro Smart Switch G2 3 way wiring?

New here, and I’m trying to do some due diligence before I purchase a bunch of these micro switches (because my house has all old wiring where the power comes into the light first). @Thegame539 I crudely modified the diagram you posted based on what @Navat604 described. I just want to make sure I got the right idea, plus it should help others visualize the modification. Essentially this is what you did and you confirmed it worked? [image] Thanks!
