Yes, we are building with GU. Due to our requirements beforehand, an electrical company experienced in building automation was specially selected. They also seem to be very active in larger commercial sectors and therefore have corresponding experience. However, when it came to the actual planning of the automation, it quickly became clear to me that they only have limited expertise in this area. That’s not a problem though, because I intended to handle both the planning as well as the subsequent programming myself anyway. Thus, I was able to save myself an additional specialist planner/SI. Nevertheless, the electrician literally told me that he would withdraw from the contract if I cut all the "lucrative" items (KNX sensors and actuators, network hardware). So now we will meet somewhere halfway. It’s not the best solution for me, but it will work out.

This works with KNX regardless of the manufacturer, because joint controls of HVAC have always been done in commercial construction using KNX. Only BAFA has to approve it later. You should put them at the top of the list. In your case, they are not only spatially very close, but most likely also willing to execute it exactly as you need. They have delivered very good work here anyway. Yes, the share is in the single-digit percentage range. But of course, it also depends on what you personally understand by smart home. If your general contractor cooperates, then I would choose option 1, because this gives the electrician more incentive. A brazen lie (or the colleague simply does not know how to manage finances).

If I look at his business building, then he definitely does not have a margin problem. :confused:

I have the same problem, developer with its own electrical subsidiary and hefty surcharges (electric roller shutters 510.- each, conventionally wired, nothing central!). I had been interested in KNX for a long time and started reading up on it, but after cost discussions with the electrician, I now have to - to the shame of all smart home new builds - rely on conventional electrics and then make it smart via radio.

Since I’m not from the IT sector but very tech-savvy, I will probably rely on Homematic IP for the most important functions to have all the essentials in a working system first, without having to tinker too much to get it running. For all nice-to-haves, I will then rely on Shellys and openHAB. I am currently putting together a list of the desired functions and the required hardware and expect to stay well below the amount demanded by the developer for a KNX preparation (!).

It is always crazy to see how people are being tricked and how great opportunities simply slip away from them because of it. And how easily this is accepted by the people despite significant capital investment.

I didn't actually accept it that easily; there were many rounds of discussions with the construction planner, construction companies, and electricians beforehand. But unfortunately, it is (at least in our area) the case that the supply of building plots is extremely scarce, and you have to be glad to find anything at all through a developer. And then, unfortunately, you are bound; building with someone else is just not possible... extremely frustrating given the huge capital investment, I have to agree with you.
