Best comprehensive SmartHome program

Or we only take the bus cable for possible subsequent KNX installation

If you only take the bus cable without the necessary further structured cabling, it is a mess. You would have to know now what else is included in the 3000€ besides just the green cable next to it.

ask if there is something that cannot be realized with KNX or only incredibly laborious (expensive)?

Many things are "incredibly expensive" in KNX, depending on how you interpret this term. But since KNX is constantly evolving and did not just come onto the market yesterday, you can really draw from a huge pool of devices and functions. You get a bunch of additional functions as soon as you expand the system with one component or another. For example, the weather station brings a lot with it to which all system components then have access, thus broadening the functionality. As for the "expensive," this is e.g. the mentioned measuring of values and consumptions. All meters are really expensive, whether electricity, water, or whatever. Also, a direct connection (channel-wise) of LEDs (e.g. strips) is not exactly cheap. Well, and of course, all the interfaces to other systems (Crestron, Modbus, Sonos, Hue, DMX, etc.) are incredibly expensive.

thank you very much for your answers

The electrician is doing the conventional wiring.

For the conventional wiring, he is laying the bus cable as a ring or spur line to all switching points.

He labels it as Free@Home preparation.

He also offered to install the weather station (800€), power supply (400€), Access Point 2.0 (700€) from Free@Home.

The electrician completely refuses a central installation.

So we are left only with the decentralized installation of KNX or Free@Home if it is going to be a bus solution.

Or we leave out the bus cables, save the money with the electrician, and rely only on wireless.

What would be your advice?

I would not exclude Free@Home 100%, even if it will be a bit more expensive and without disadvantages, the installation afterwards on your own is much easier than with KNX and the programming too (even if there are limitations) with Free@Home my wife could even program something, with KNX no chance.

With Free@Home, integration of bus and wireless devices is very easy.

Yes, then just take Free@home. As it looks, the WAF there is even quite okay. So go for it.

The WAF factor is vastly greater. I would easily trust myself to program everything with Free@Home.

So you would prefer Free@Home over a wireless smart home because F@H is wired?

Cable is always better than radio in a non-mobile environment where a certain stability and resilience are desired. What you may want to add as radio later, you can integrate then.

Since F@h appeals to you in many points and is even obviously a favorite of the electrician, then have it executed that way.

Do you know a little bit about F@H?

I still have a few questions/concerns

Can F@H be controlled with Alexa?
especially by voice with Alexa?
For example, Alexa, turn on the living room light.
Alexa, set the living room blind to 50%

We can only do the F@H preparation; currently, there is no money for more.

I would trust us to replace the actuators of the light switch and blind switch (button + actuator at the switch) ourselves and connect them to the bus.

How can F@H be optimally prepared?
1. Do conventional wiring and lay the bus cable to all switches (light and blind) as well.

2. Have the power supply connected in the distribution board.

3. Have the weather station installed already
(Where would you mount it on the satellite mast?)

Thank you very much for your help, your opinion and experience are very important to me
