As far as I can assess the electrician, he definitely will not give me the parts from KNX beforehand for parameterization.

If that is not possible afterward, he will have to do and install it there. At least in the basic equipment, and I would then make the further adjustments and automations later.

For KNX, we would have relied on MDT and the MDT glass pushbuttons, possibly first the cheapest pushbuttons and then later converted to the glass pushbuttons ourselves to save money during the construction phase.

Yes, but we will have to die sometime if the electrician does not want to do KNX, either Free@Home only BJ or as a last resort radio.

Different electrician? Or is it a do-or-die situation with [GU], developer, or prefab house provider? As mentioned, he doesn't have to configure anything for the handover or tests; everything can be done via the buttons on the device, especially with [MDT].

Yes, unfortunately it's do or die with the developer :/

What would that look like exactly? I haven't really understood that yet (Sorry :/)

What does the electrician have to do?
-laying all the cables is clear
-installing the devices, actuators, and switches

what else? Are the standard functions like light on/off natively available immediately without any parameterization?

As I said, he doesn't have to parameterize anything for the handover or tests, that's all doable via the buttons on the device, especially with MDT.

or what did you mean exactly by that?

Exactly. With MDT, everything can also be operated directly on the device with the normal actuators. Take a look at those things on the website, then it will become clear.

What does the electrician have to do? -laying all cables is clear -installing the devices, actuators and push-buttons

So he has to (ideally should) lay the cables and wire the control cabinet including installation of the actuators. You can easily connect all sensors yourself to the green bus line, that is low voltage (and not difficult at all).

Are the standard functions like light on/off natively available immediately without parameterization?

Be careful! You can switch on and off every light channel and move every roller shutter up and down AT THE ACTUATOR in the control cabinet. That means the electrician can test whether he wired everything correctly. THEN it's your turn: If the KNX bus has power and can be connected to a PC, you can start bringing the actuators into the system with ETS (assigning addresses). Then you connect the first push-button. Ideally, you have already made a division for the group addresses at home beforehand. Then you connect the first push-button and the first actuators with the first group addresses. For me, that was e.g. a push-button in the hallway that could initially only do "lights upper floor on/off," "lights ground floor on/off," "all off." From there you continue working further.

Thank you very much.

The electrician only needs to connect all consumers star-shaped, e.g. roller shutters and lamps. The underfloor heating is connected to the heating actuators in the control cabinet with the control valves.

How are the sockets connected in KNX? Is every socket really connected star-shaped or do you use one 5-core cable per room with which you then have 1 circuit for constant power + 2 switchable circuits?

The electrician only needs to lay the bus cable to all switches and sensors; buying and connecting the sensors is then done as a DIY task?
