Request: Centralized Wired home automation solution

Hardware
1

I am looking for a centralized electric panel for all home lighting and electric sockets to be controlled in one single panel , any guides on DIY solution that works as KNX is way too expensive I want to build something similar but with DIY I am good at Arduino and ESP programing and python , just looking if might some one has build the right pub to use for my project . for example as KNX solution I like the idea of KNX all centralized in one panel and then you distribute sensors or buttons , I am looking to build my own to be cabled , wifi is good but not really reliable or solid as good as wired stuff.

I have seen kin cony solution but to use serial to communicate is way too old for me any suggestion will be very welcomed beside your experience .

Just to know I have home working good with Sonoff tasmotized dimmers switches , but I want something more solid to work on its own and solid like industrial stuff that u do once and forget forever.

You don’t say where you live, but if you are in Europe, have a look at HomeMatic IP Wired.

In my opinion, it’s a very inefficient way to wire a house.

I’m sure I agree but maybe there is special scenario where doing this makes sense

Look for NEMA box
Many allow adding mounting rail for equipment. If single large is not enough multiple will.

I am living UAE,Dubai , UK standards are followed here , 220V if this is what you are asking about .

I agree with you at certain point , everything works with Wifi, zigbee and Z-wave , but wired is more Stable in my opinion does not rely on other dependancy like wifi AP or another stuff zigbee GW or wave GW , wireless stuff works easily but not 100% percent availability you always has to restart something from time to time , centralized and wired solution looks professional and rock solid once working it works and never stop unless something is broken I mean hardware failure.

Professional Building management solutions are always wired , KNX as example , what I am saying if your are building new house it seems the best option to have it wired and designed this way.

I agree wired data lines are superior, but I wouldn’t wire all sockets and lights back to one point.
I’d take a more modular approach. Of course you can wire to each distribution point.

I have 28 lights installed upstairs in my house. All are individually controllable, I wired all of them with less than 100m of cable. If I wired them all back to a central cupboard I would have used 500-600 meters of cable. I would then need 28 dimming units etc.

Schneider C-Bus might meet your needs. I use it here. Switches - if you use the C-Bus ones sit on a 2 wire low voltage star or ring typically implemented with a CAT5 cable.
