Okay, the signal is great I had 60-840 as a best range out of a max 0-1024. The sensor wires will be passing directly between the AC switch wires so we will see if or by how much the signal degrades. I don’t think more than a few hundred are needed since we are just looking for rising and falling edges.
Todd, went with a cap inspired by you. Got the sensor closer, added a light baffle, and a place to cable tie it in. This allows for some adjustments if needed.

Led closer to the center works better for me.

Sharpie and WhiteOut, seems to work better than the reflective decal. But I wan to revisit this now that I have a better light baffle in place.
