Smart home without switches? P.Hue, Home Assistant, Homematic wired IP

Good morning,
well, I see it a bit differently, since routers and Devolo now coordinate very well regarding disturbances, I have very little concerns about that. Your prejudices about DLAN probably come from the past. Nowadays, there are few problems.
That's why I don’t have big scruples about it. And at the moment I am very satisfied with it in my own home.
Network and Wi-Fi everywhere I want it....

I’m happy to present this again..... so I want to build an electrical installation centrally, which makes sense since it will be a shell construction. I will assemble the cables and the distribution cabinet together and pull cables in the house. The central cabinet will supply two apartments. Everything there should be smart. That’s why I came across homematic; an alternative would probably be Busch Jäger. I didn’t want to install switches, since there are basically no rooms in the apartments, only large spaces; the only “room” is what you could call a toilet cabin. That’s why I wanted to have a display for operating everything.
And since I want to control lighting holistically via this display, as well as the blinds, air conditioning, and heating, I’m looking for a suitable system. There are then Raspberry Pi solutions like IO-Broker, Home Assistant, etc. that can network these different systems and make them operable. I’m not so sure yet about Busch Jäger free@home. Nuki will also be integrated there for PIN input from outside and general access control to the apartments.
Of course, I don’t want to tinker forever, but a KNX system with expensive software faces an open community with system solutions that have a CPU for about €70.

For me, the question is not whether I use a tinkered solution or Busch Jäger; the question is rather whether BJ is so open to communicate with all systems in the same way in order to, for example, activate the condensing boiler when the air conditioning no longer keeps up with heating so that it stays warm in winter. Or only use the air conditioning when the sun is out, since the photovoltaics are smartly accessible. Or the electricity meters I need for this. I just assume they can all operate the blinds and lights.

And since the system has complexity, I approached the specialists here.

The complexity here is not in wiring and whether there is a network socket but in linking and unifying interfaces and their operation..... and exactly there I need expert knowledge.....

So I look forward to experiences with free@home, homematic IP, IO-Broker, Home Assistant or alternatives that might be better able to make all these systems operable together.

And since, as is the unanimous opinion here, I have no idea and need help, I look forward to constructive answers.

If you want to have something like that in a house where you plan to live for 20 years or more.

To me, that sounds like a makeshift solution that will probably turn out to be far too prone to failure.

Just the fact that you use 3 systems (Raspberry, IO Broker etc.) that are supposed to work smoothly together.

Likewise, "no switches" for some functions, a control button makes more sense than just using an app.

So, I'll admit that I'm an absolute iobroker fan.

I have had the system running stably for 2 years now. Included are, among others, shellys, homematic, vacuum robots, lawnmowers, photovoltaic system, washing machine, dryer, dishwasher, NAS, etc.

You have to say that this thing is pretty powerful. A lot of small and large scripts run on it that are supposed to automate everyday life to some extent. I also built a visualization that hangs on a tablet in the hallway and is permanently powered there.

It looks something like this.



So, regarding networking, I can imagine that with a lot of time and patience for you. But for the guest without a fallback, I'm completely on the side of the others. For example, what happens if the guest doesn't charge the tablet, or plays around with it so that the visualization suddenly disappears, the tablet crashes, etc. and so on.

Hi ok that looks good! IO- Broker so…. the tablet yes I wanted to mount it permanently on the wall in a steel case with charging… no one should carry it around now…. a lot of time and patience? To configure? I rather hope that with good planning a lot can already be taken care of…. ☺️ Deciding on which system, wiring, etc.

Well, if you naturally want to map all the scenarios you throw into the room, like heating, climate, blinds, lighting, then quite a few scripts have to be written for that.

It's certainly not just a few things to click together quickly. I've already invested quite a lot of time until everything runs smoothly. Not to mention the visualization.
You should also consider that the visualization in iobroker only runs in a browser. Occasionally, Firefox in my case hangs briefly. For me, that's not critical, I just press the app again and the visualization reloads.

Who will do that for you then?

well, I see it a bit differently, since routers and Devolo now coordinate very well regarding interference, I have very few concerns about that, your prejudices about DLAN probably come from the past. There are hardly any problems nowadays. That's why I don't have many scruples about it. And at the moment, I am very satisfied with it in my own home.

This is not about the past, but about the situation on site. The stuff can work really well in one apartment, while in the next property the same technology can be a disaster. Especially if you are considering this here:

I am happy to present it again..... so I want to set up an electrical installation centrally, which is currently convenient since it will be a shell construction. I will assemble the cables and the control cabinet together and pull cables in the house.

... then just do it properly and run network cables where you need them and don’t start in a quasi-new build with such junk.

That’s why I came across Homematic, an alternative to that is probably .

No, fundamentally different things. HM is relatively open, BJ is a closed solution with 1-2 compatibilities.

So I am looking forward to experiences with free@home, Homematic IP, IO-Broker, Home Assistant or alternatives that might be even better able to make all these systems operable together.

From that selection, I would take Home Assistant. Don’t mix too much, otherwise you won’t have any fun in the end and your guests won’t either. HA has an extensive integration list. You should check beforehand whether the planned devices will work together. No matter what, out of the box, that won’t work with your requirements.

And since, as the unanimous opinion here is, I have no idea and need help, I welcome constructive answers.

Then you should maybe also start trusting people who know what they are talking about.

I rather hope that good planning can already solve a lot …. ☺

Again no or no with reservations. You solve a lot with experience. Of course, you can buy all kinds of things based on data sheets, but the fine pitfalls are not listed there. If you stick to one system, you can plan relatively well, but if you mix wildly, it can get interesting. And “assuming everything works together” inevitably leads to a rough belly landing.
