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?

I find Shelly wifi fine for mains powered wall switches but motion sensors and contact sensors and anything else with a battery need ZigBee IMO because the battery life and latency with wifi is absolutely intolerable.
