Hi, I am in a very similar position and would love some advise from people.
We are in the process of buying a new build apartment here in Germany, which is already planned with a basic Gira knx install. However, now that it is time to put forward our “sonderwuenche” - special wishes, the cost is growing and I suspect part of the problem is how the lighting is being designed.
Currently, all switches are knx buttons. Heating is underfloor heating with knx control, and a Gira video doorbell - so far so good. The question is about lighting.
The default that is provided is simply switching of lights somehow with knx. Dimming is a significant extra cost of about 200EUR per circuit. I suspect that this is a simple 230V knx dimmer. We will generally want LED downlights in a drop ceiling, or some hanging lights, but ideally also LED based. My wish was to have everything dimmable, and I would love to have RGBW or at least colour temp adjustable.
So my question is which way is best to go technology wise for the lighting? I am happy to mix and match technologies a little if it makes sense. I already have a few z-wave sensors and Wifi lights that I have been playing with in the past but this would be on a bigger scale.
From my understanding, knx with dali for the lighting might be the right option here. I would love any advise.
Further info, WAF is always important, but my wife also loves tech, so maybe can forgive the odd issue. I already have the ETS6 license, as I figured I would be needing this and I made use of the black Friday specials.
I suspect the high pricing for the special wishes are due to the building company using expensive 230V dimmers from Gira. I also need to decide if I pay extra for the Gira X1 knx gateway, or if some alternative gateway would be better.
