ᐅ Experience with Shelly Pro Series vs. Homematic IP Wired vs. Bus Wiring Systems

Hello everyone,
Currently, our shell construction is completed, and soon the electrician will start the rough installation.
We already had a few appointments beforehand where a “smart home” package was offered to me.
The electrician commissioned by the developer offered a complete KNX automation system for a “small additional cost” of about €15,000 (around $16,200).
This included the Gira X1 system with server, switches, wiring, documentation, etc.
The high price discouraged me, so I decided to go with the conventional option.
My plan was/is to automate the following:
a) Operate and automate roller shutters/blinds using Shelly flush-mounted actuators, possibly also controlled by a weather station
b) Control some sockets (especially in our child’s room) using Shelly devices with timed on/off switching
c) Manage lighting through Philips Hue
I am still not completely happy with my decision for conventional wiring.
It bothers me that I have different manufacturers involved, which makes central administration rather unlikely, at least as far as I know. (Is there a way to centralize control for my purposes? If yes, please let me know 🙂 )
Also, the automation would always run over Wi-Fi. I would much prefer a wired solution.
In this context, I looked into the Shelly Pro series.
This is basically the “wired” version, which should be enough for my modest requirements.
Has anyone here worked with these devices or, even better, installed them?
There are some YouTube videos, but mostly single examples, and not very conclusive.
I also really like the Homematic IP wired system. It would allow central control installed in the distribution board (DIN rail). However, here too, there are issues with the connection and required inspections.
The more I think about it, the more I consider having the electrician install bus wiring after all, while I set up the network and server infrastructure myself.
Wiring a patch panel and switch is not a problem for me.
However, I have some doubts about whether I have enough experience to connect the server myself.
Furthermore, there is the challenge of designing and programming the system and routines.
Basically, I am technically inclined and can read into certain things.
I wouldn’t shy away from it but am unsure whether I might be in over my head?!?
Besides, everything would have to be certified by a licensed electrician!
I told the electrician about my plan; he generally has no problem with it, but I would need to install the cables in the basement myself.
He said he wouldn’t connect any hardware he did not supply or install himself, for warranty and liability reasons.
My suspicion is that he makes less profit with this variant and that’s why he said this... and everything would still need approval anyway. Whether this will go smoothly... I have no idea.
For my part, I want everything properly certified, also because of insurance and similar concerns.
My question now:
Is a KNX-based bus solution “overkill” for what I want to do, or are WLAN Shelly devices sufficient to integrate performance data into the FritzBox?
An Ubiquiti PoE ceiling access point is planned/being installed on every floor. So, hopefully, Wi-Fi connection will be sufficient if I end up going with just the flush-mounted Shelly devices.
Maybe some of you have tips, suggestions, or ideas...
I would like to thank you in advance for a constructive discussion.
Best regards,
Tom

Am I correct in understanding that using Shelly Pro actuators involves roughly the same wiring effort as using KNX actuators?It’s essentially just a central KNX actuator, but with a LAN connection instead of the traditional green bus cable. You still need push-button sensors, though.PMW1993 schrieb:
The 1000€ is only for the materials for Shelly and the anemometer Will there be a rough breakdown of what is included in your calculation?
For under 1000€, I can get 8 blinds channels with KNX as well, including power supply, IP interface (or even a router), and wind measurement.
Since it's fewer than 5 devices, the ETS software is free of charge.
