Nothing you're doing is to code anyway. So just git er dun bra.
Ya, I don't think fishing romex through insulation meets code. I also doubt wiring a sconce into an electric outlet without any kind of manual on/off switch meets code. It's working great with the wink relay switch, as well as controlled via smart phone, but there isn't a physical switch that cuts off power to the bulb. Otherwise everything should be wired correctly and I'm using correct materials so it's not THAT bad.
On that note, the second one went in MUCH easier. Ground wire was cut short again, but long enough that it wasn't hard to get to. I was able to get the box out without breaking off chunks of drywall. I was even able to fish the wire through without problem. Of course nothing goes without issue, the glass on the second sconce was shattered. I should have the replacement in a few days.
Sorry, no pics of the work, but here is a couple of the finished one.
Dimmed about as low as it will go, any brighter and it washes out the pic on my phone.
Before you yahoos say anything, replacing the blinds and painting the walls a different color are on the list of things I need to do. Also, ignore the Leon pics, it really is level.
