The sensor probably requires you to use incandescent lamps. The sensor tickles a small current through the lamps to get its power. Same thing happens with CFLs.

Let's see if I can get this conversation back on track ;) The question of insulation (I will call it shielding) would probably come from the thought of electromagnetic interference, or induction. This is often seen when testing to see if a wire is hot with one of those non-contact glowing voltage testers. For example, it will show the red wire in a 12-3 cable as hot when only the black is really hot. This is not likely the problem, but there might be a small chance of it contributing IF the switch legs of the lights and fan run up to the fan junction box together in a 12-3 cable, before splitting off to the lights. A fan motor runs best on a pure sine wave. A distorted wave can cause a hum. LED bulbs can also buzz for the same reason. All dimmers listed for LED bulbs do not play well with all bulbs. It can often be a guessing game of changing out dimmers or bulbs before you get the best combination. A less than optimal combination can cause poor power quality throughout the house. (A closer proximity can also make the effect worse, in the right circumstance) This is 'inside the wiring' and has nothing to do with "shielding" with respect to the fan motor. You may have more electronics causing this than just the LEDs and dimmers. The dimmers may just be 'the straw that broke the camel's back' or the majority of the problem. https://www.fer.unizg.hr/download/repository/Power_Quality_Primer-_Barry_W._Kennedy.pdf I do not know why that will not work as a whole link.

If there is anywhere to use recessed lighting it would be your kitchen. Also add under cabinet LED's. Once those are done, you may find the addition of 3 pendants here a bit of overkill. As for the ceiling fan, is it needed in warm weather? Fan lights rarely serve as room illumination except for getting in when its totally dark. They are completely inadequate for anything else. Looks like you're sampling some paint colors by the stairs. Don't go for the paint until the lighting is completed so you get true colors. If you key paint to current lighting you'll be disappointed with it when the upgraded lights go in. I think a pair of chandeliers for each of your dining areas will be a big help. Some uplights under plants flanking the TV could be a nice touch. You may want to consider unloading the mantel of its clutter and having sconces installed on that wall. The windows seem awfully low, so a "fool-the-eye" window treatment that uses shades and panels to visually extend the window onto the wall above it will be a big improvement to your overall look. Here's a chart to help with TV/sofa placement. and a chart for picking a rug, which you should consider to anchor the sofa and seating group.

The diagram Sammy posted is a good guide for the height. You could wire for your lights even before you decide which mirror(s) to buy. We did a 6” backsplash and started our beveled, unframed mirrors immediately on top of the splash rather than leaving a space there because the mirrors were filling the whole space wall-to-wall.
