Bypass for a 10W smart bulb + Blue

Thank you @Bry and @hydro311!

With my situation, the order of difficulty is:

  • Anything that involves opening up ceiling/drywall (virtually impossible)
  • Rewiring at the light fixture (bit of a pain, but doable)
  • Rewiring at the switch (no problem)

Also, I’d actually prefer to not have a bypass since I want to do this to many lightbulbs, and am concerned about the additional power usage.

So given all of this, I don’t mind trying to rewire at the light fixture at all. However, I don’t know exactly what needs to be done there. A search brought up this thread and @Bry’s post there seems to also recommend the same approach. But what I have trouble understanding is what needs to be done at the light fixture.

I haven’t opened up my light fixture yet, but it’s an older house, and what I imagine is, ignoring ground, there are two wires: neutral, and a line (hot). The line would come from the switch.

What would I need to do at the fixture given this? I’m guessing I’m mistaken about what I’d find in the light fixture? If there’s a circuit diagram or a howto that anyone can point me to, I’d be most grateful. Thanks a ton!
