Having no ground is a huge pain, gotta balance the lines well to so that big power draws (ovens, pumps, dryers, etc) don't cause voltage fluctuations (current issue my redo is fixing slowly but surely, but it's been burning my LEDs, getting dimmable bulbs does help though).

My data lines (currently phone lines, and cable just stapled on the outside of the house ...) are in the same process of new line and replace, but starting the line from my router instead. I'm willing to do a line per room and use dumb switches and access points in the rooms with more devices. To keep my wall from looking like an old telephone switch board operator 😅
