Shelly Pro Series vs. Homematic IP wired vs. bus wiring experience

Hello everyone,

Currently, the shell construction is completed at our place, and soon the electrician wants to carry out the rough installation.

We already had some appointments beforehand, where a "smart home" package was offered to me.
The electrician commissioned by the developer offered me a complete KNX automation for a "small additional cost" of about €15,000.
This included the Gira X1 system with server, buttons, switches wiring, documentation, etc....

The high amount scared me off, and I decided on the conventional option.
My plan was/is the intended automation

a) to operate or automate roller shutters/blinds via Shelly flush-mounted actuators (possibly also via a weather station)
b) to time-control some sockets (especially at our junior's room) with the Shellys to turn on/off
c) the lighting control via Philips Hue

I'm still not completely happy with my decision for the conventional wiring.
What bothers me is that I have different manufacturers, and accordingly, central administration is rather not possible, at least I don’t know of anything like that yet. (Is there a centralization option for my purposes)? If yes, then please share :)

Also, the fact that the automations would always run over WLAN bothers me. I would prefer a "wired" variant much more.
In this context, I also looked into the Shelly Pro series.
In principle, that is exactly the "wired" variant which should be sufficient for my low requirements.
Has anyone here ever dealt with these parts or even better, carried out an installation?
There are some YouTube videos, but only with individual examples and not very conclusive.

I also like the Homematic IP wired system very much. Here, the central control could also be installed in the sub-distribution board (DIN rail). However, here again there is the issue with the connection and the required approval.

The more I dealt with the topic, the more the idea came to me to still have a bus wiring installed by the electrician and to handle the network/server landscape myself. Wiring a patch panel and switch is rather no problem for me.
However, I already have doubts about whether my "experience" is sufficient for the server connection.
Furthermore, there is also the difficulty of creating or programming a conception and routines.
Basically, I already have an affinity for technology and can read into certain things.
I wouldn’t shy away from that either, but I don’t know if I might overextend myself?!?!
Also, it must then be approved by a certified electrician!

I informed the electrician about my plan; he generally has no problem with it, but I would have to lay the cables myself in the basement.
He said that he also does not connect any hardware that he does not procure/install himself for later warranty reasons, etc.
My suspicion is rather that he makes a smaller "margin" with this variant and is therefore making this statement.... and it would also have to be approved. Whether that all goes smoothly...??? No idea.
For my part, I just want everything to be properly approved, also because of insurance issues, etc.

My question now:

Is a KNX-based bus variant overkill for my plan, or are the WLAN Shellys enough to enter the performance on the FritzBox that way?

A Ubiquiti PoE ceiling access point is planned or being installed on each floor. Hopefully, WLAN connection will then be sufficient if it is "only" the flush-mounted Shellys.

Maybe one or the other user here has a tip, suggestion, etc...
For constructive communication, I would like to thank you in advance.

Regards
Tom

For my project, a KNX-based bus variant is like using a sledgehammer to crack a nut

Yes

or are the WLAN Shellys sufficient as well

Yes

It bothers me that I have different manufacturers, and accordingly, central administration is rather not possible, at least I don't know of anything like that so far. (Is there a centralization for my purposes)? If yes, then bring it on :)

He said that he does not connect any hardware that he did not procure/install himself due to later warranty etc.
My suspicion is rather that he has a lower "margin" with this variant and therefore makes this statement... and it would still have to be approved afterwards. Whether everything runs so smoothly then...??? No idea.

Probably both with the electrician. KNX programming is not trivial.

Either the small solution with Shellys etc. (you can link various manufacturers via io-broker) or real KNX. But then say goodbye to the normal electrical installation and automate properly. This has nothing to do with "I want to control the blinds remotely," but is real automation = logics and routines

Ok, understood. I almost thought so myself. However, I would like to stick with the ShellyPro series again, or rather, I have some uncertainties. As far as I could find out on the internet, these "Pro-Shellys" are actually the "wired version" of the flush-mounted actuators which are located in the WLAN, right? The "Pro-Shellys" are powered in the field distributor and can be connected to the home's network via an RJ45 connection through a switch. So you wouldn't be dependent on a WLAN connection. Has anyone in the community had any experience with this so far or even installed it themselves? My goal is to have these actuators wired in the house if possible. Are there possibly other options for my needs? KNX etc. are initially ruled out. Thanks in advance

Loxone?

Shelly well, the question is how good the support is and how reliable the whole system is afterwards?

However, you'll also end up around 15,000 euros but you are more flexible than KNX because the system includes software

Why either/or?

I am also facing these questions. I will also install a UNIFI system again. I will have the cables for the roller shutters laid all the way to the connection box.

I had also considered switchable sockets. But I decided against installing them individually in the utility room. All sockets will be installed "deep" so that I can possibly install WLAN relays like the Shellys later.

Only with the lighting and the control elements (roller shutters, lighting, etc.) in the room am I still unsure. I am currently leaning towards Loxone.

I have some experience with 'DIY home automation' – so I can also use different systems.

Wlan is just the problem, since the routers often come from the provider, if they send a new one you either have to set up the wlan from the old one again hoping it works or relearn all the components. If you can do that yourself, okay, but if they are installed in a way that you can't reach them, it gets exciting.

We have been living here with Loxone for 2 years.. and it works
