ᐅ New Construction – Which Smart Home System?

Hello everyone,

I am finally planning to build our own house with my family. I don’t want to do without a smart system and have already done some research.

Loxone is basically off the table for me because it mainly relies on its proprietary system and products.

Of course, I have repeatedly come back to KNX (as here in the forum as well). However, I am not entirely happy with it because I don’t want to have to call a programmer every time I want to make a change; I also don’t really want to buy the ETS license. Additionally, I want to integrate and network fingerprint scanners, Sonos, and a heat pump, but I haven’t fully figured out how to do this with KNX.

The house basically has two floors with an open-plan kitchen/living area, entrance hall, utility room, bathrooms, children’s rooms, bedroom, garden, and so on.

The following systems should be connected:
- Lighting (some dimmable)
- External blinds / weather station
- Underfloor heating
- Heat pump
- Music system (Sonos)
- Fingerprint access
- Video intercom
- Some switched power outlets
- Photovoltaic system

Since I am technically fairly knowledgeable, I want to be able to manage, adjust, and optimize my system myself in the end.

Does anyone have good input here? Or already experience with Loxone, KNX, or others?

Thanks and best regards,
Stefan

Heating and shading 11k?
Maybe this item is that high just to qualify for the new, larger subsidy related to installing a heat pump?

Thank you for the overview.
I wonder how much a traditional installation without smart home features would have cost. You probably don’t know that, do you?

@truce
For the €50,000 (about $54,000) subsidy, it’s enough if the heat pump is included.

Since you don’t know any details, the statement is rather irrelevant. In this area, you can spend a lot of money. And some people don’t like the standard generic glass switches and prefer something more expensive?
Then tell me where so much money can be spent there? Apart from the control elements.

- (many) SMI motors or KNX servos instead of standard motors with inexpensive blind actuators
- expensive weather station, often with external sensors for different facades
- extensive heating control, e.g., with temperature sensors embedded in the screed in addition to air measurement and corresponding evaluation
- complex logic for shading control combined with heating regulation based on the above sensors
...

So far, this is all just speculation. Maybe Notstrom will add something to this. There are many possibilities.

3600 € for the network is also quite a lot.

If you want, you can upload the full offer including the plans, then people can give you feedback and especially provide you with some advice in advance.

Heating and shading for 11k?

A few channels of heating actuators, blind actuators, a weather station, and glass touch sensors aren’t usually that expensive.

The other items are somewhat reasonable in cost.

Edit: The satellite system is also ridiculously expensive. We have 16 connections and stayed well under 1,000€ (please keep the currency) but that was in electrical installation.

The 11k includes the complete visualization system etc., since we will submit it to the BAFA – this is the current work status, not final. The satellite system is...
