Home automation is the residential extension of building automation.

It is automation of the home, housework or household activity.

Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, security locks of gates and doors and other systems, to provide improved convenience, comfort, energy efficiency and security.

What you wish you should have done smarter if you were building a house to accommodate all of the IOTs connecting to HA (alien.top)

I am building a house and trying to avoid power bricks and cables hanging on the wall for motion sensors, blind shutters, "add next smart house blinky here".

This is just an aexample photo:

example HA rooms

So I was thinking each IOT needs to have internet connection anyway. What about if I run a single CAT cable to each room, and position a switch in each room to split to couple CATs in each room (power socket, tv socket, window, ceiling fan). Main CAT from each room to go to the server room router. That way I can have one cable per room coming out from the router. And with some inexpensive POE switches in each room I can split to extra IOTs.

That way I wont be saturating the home wireless and needing expensive APs. And in the same time can deliver POE. Alternatively I can modify the CATs to run only 4 wires for 100MB network and remaining 4 for 12V if POE injection is complicated or routers cant deliver required IOT current.

I must say most IOTs will be DIY ESP/Arduino/MCUs

Is it possible you guys think?

Don't run cat wire, run conduit in the walls. In 20 years you might want to fish something completely different. Put conduit to every room and every thing you think might need it and you can EASILY put whatever low voltage you want through.

For your electrical, just do all 4 conductor instead of 3. Someday you might want it and it's a modest increase in cost. Run 10g where you require 12, run 12g where you require 14. You waste less electricity in the walls losing less to heat.

No, you shouldn't run 1 wire to a room and a little pocket switch for each room. That's an IT nightmare. Have a closet with homeruns. Have all your POE on ONE switch and you can have a battery backup on it, you can MANAGE your devices there. Pocket switches are last resort in any deployment as an afterthought, not a forethought.

You're gonna eventually "saturate your house with wireless" Just plan now around a few good accesspoints.

It's all going to move to matter and thread in the next few years if they can get the spec together but you should design around flexibility.

Conduits. I just did a remodel and am already regretting not finding a better way to incorporate some conduits.
