Ask HN: New Homeowner Suggestions

If all goes well I will be closing on a house mid-April and I was wondering what suggestions people on HN would have. I'll have about a full month and a half of overlap with my current apartment so I've got time to run wires/etc if I want.

This is pretty open-ended question, I'm interested in everything from "Take pictures of X". "Run ethernet before you move in", "Install a energy/power monitor", etc.

I plan on installing Zigbee switches in most if not all of my light switches and I use SmartThing with Alexa/Siri(homebridge) to control them.

Anyways I'd love to hear from HN's homeowners about what they would do differently or what they did that they are glad they did.
