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

Hello,

I am currently thinking about the electrical installation in a house with two holiday apartments. KNX is too expensive....Thinking about two control panels to operate the apartment....Shutters, lights, Philips Hue I find great because of the colors and light spots you can place everywhere... The idea now would be to set up a distribution with Homematic IP Wired....and run a Homeassistant via Raspy.... I would use this on iPads in the apartment to then be able to control everything smartly from two places in the apartment....Light scenes, shutters, heating....by the way...are there smart air conditioners or heaters that can be integrated into the system?.....And DLAN in the distribution cabinet.... That's roughly how I imagine it.....has anyone ever implemented this or any tips etc.

What you are describing so far is not smart but remote controllable. You don’t need that just for making things colorful. But colorful light strips are the new ar...antlers. What do you mean by DLAN in the distribution cabinet? Do you even have a proper plan for LAN and WiFi? Sure, you can mix many systems. But then you also need the time and knowledge to make sure everything works. All in all, KNX is cheaper. Are we talking about one or both apartments? How do you separate that in the network, access, and control?

Too little information.

What is your "prior education" in this area? Are you familiar with protocols and electrical engineering?
Is it all for the 2 holiday apartments?
What is a DLAN?

Well, LEDs are a matter of taste. I find the Philips Hue concept quite nice. Also for the wiring. You just put 230V everywhere and you’re done. The rest is done by the app. As for DLAN, yes, I feed the internet into the distribution board and distribute it to both apartments. So that internet is available in every corner. Devolo or something like that. Yes, the whole setup is for two holiday apartments, I imagine creating a dashboard for each apartment. Hmm, Homeassistant can even control KNX. I just think Homematic IP Wired in the distribution board is cheaper. Only how to get the heat pump or air conditioning smartly connected there, I’m not sure yet. Everything else seems intuitively integrable into Home Assistant. If I understand correctly, you save a lot of wiring this way, a few motion detectors at critical spots like the bathroom could then also be wireless via Homematic. I can’t imagine KNX being cheaper with a €100 Raspberry and a few distribution board modules from Homematic IP; I estimate the programming effort to be similar. Only feasible for laymen and without having to pay much for software. I don’t fully understand the pros and cons of the two solutions yet. But the Raspberry solution seems to be much cheaper to implement. Knowledge-wise, well, MQTT and JSON are terms I know, and I guess I’m allowed to pull cables. But so far I’ve only read and never played around. This applies to both KNX and Raspberry. Saludos Bampa

Unfortunately, you have answered almost no questions. LEDs are useful. Whether you have to make everything colorful is the question... I have the feeling that you have little knowledge of network technology or home automation. What you describe has nothing to do with SMART but rather makes components remote-controllable. Air conditioners and heaters can also be integrated. Feeding internet through power lines is not a good idea. How do you ensure good WiFi coverage? What speed is required? How do you separate the networks? These are two residential units... With a lot of tinkering, you will get quite far. Whether it then works reliably is another question. It’s still not smart. Will you then go there when the batteries in the wireless motion detectors are empty? If you have to lay cables anyway, you can also install KNX, LAN, etc., or wire everything. With KNX, you also have the actuators centrally in the control cabinet.

Hello,
Take a look at free@home from Busch-Jaeger. With it, you can implement everything completely, without extensive programming and tinkering solutions.
Whether it makes sense to do without switches entirely is a matter of taste. Personally, I don't think that's sensible.
