ᐅ Bus cables and power cables routed star-shaped into the distribution cabinet

Hello everyone,
we have a garden shed (one room) that has been unused for several months/years. I would like to move forward with the renovation. Originally, I planned to use the garden shed as a KNX test area.
Current condition:
Questions:
I will need to read up again on KNX and smart home as a test area and might have questions about components later on.

Current condition:
- I’m not sure if it’s a good idea, but all power outlets/bus cables were wired in a star topology to the sub-distribution board. Here is an overview of the amount of electrical cables:
- I have a sub-distribution board with two sections:
- First section: 5 rows with DIN rails
- Second section: multimedia area
Questions:
- It probably wouldn’t make sense to protect each light or power outlet separately. Are there any terminal blocks or busbars where individual lights or outlets can be grouped before being protected as a whole? (e.g., Hager, Wago…)
- The same applies to the bus cables. I should have created one or two rings here. Now I have about 20 green cables in the sub-distribution board. Are there terminal blocks or busbars (preferably for the multimedia area) where the bus cables can be consolidated?
I will need to read up again on KNX and smart home as a test area and might have questions about components later on.
So, an MDT glass switch either has two levels with six functions each or three levels with four functions each (because the top two buttons are used to switch between levels).
The glass switch itself does not have a timed switching function; this is provided by the glass control unit. The control unit has only four direct buttons but offers 20 functions accessible through menus, which can also be executed on a timer.
The control unit acts as a basic visualization interface. Take a look at the manual on MDT’s website. It might be exactly what you need.
If you definitely want to control something via smartphone, you will need some kind of visualization system.
For example, Node-RED running on a Raspberry Pi...

If you really want to fit everything in, you might consider using something like the Tantron 2.6" touch display. You can then fit everything on the maximum of 10 pages – if I haven’t missed anything, that should be possible. However, scheduling is more practical through a dedicated unit (e.g., MDT) or possibly via Node-RED, as already suggested.
A smarter approach would be to think about what can be automated – 10 pages of control elements aren’t very smart. It’s better to design the sensors so that (almost) everything reacts automatically to presence, time, sun position, temperature, air quality, dryness, weather forecast, water level, and so on.
