ᐅ Consultation for Smart Home New Construction Wireless Systems

Hello everyone,

I am currently planning the components for my smart home in a new build.

  • The electrical installation will be done conventionally.
  • Roller shutters controlled only via smart home, without physical switches. Seasonally controlled (Sonoff relays).
  • I also want to control underfloor heating circuits solely via smart home. For this, I would need temperature and humidity sensors in the rooms. Which ones would you recommend? Which relays could I use for the valves? They are just on or off. I would probably need about 8 to 10 units.
  • I want to override light switches in the rooms using Shelly devices.
  • There will be touchscreens on two floors displaying all information and control options.
  • Additionally, Android apps on every phone for home control.
  • In the living room, a configurable button with a display? What would be suitable here?
  • Alarm system with motion sensors and possibly door contacts.
  • Control via OpenHAB.
  • Which sensor can I use to control any actuator with a simple wall switch?
Do you have any ideas or suggestions? Everything should be relatively affordable to implement, and I’m happy to put in programming effort myself.

Thanks in advance

You keep saying you don’t want a KNX vs. the rest discussion, but you constantly call everything else a makeshift solution. That won’t lead to a reasonable discussion; it’s just shooting down everything else.

That’s not the case, I only call makeshift solutions what they actually are, for example:

The Pi, well. I’m also marked by that. Back then I had the Pi with FHEM and the EQ Max thermostats, plus the 433MHz wireless sockets. That was (sorry) garbage. Then the SD card broke after half a year and everything was lost. No, never again.

That was the reason for this statement. If you read the thread, you would know that.

It’s fine that you rely on z-Wave. At least this is the only standard (besides the ones already mentioned) that is taken somewhat seriously in home automation and has a future. The alliance has recognized that only through diversification and standardization can you get a share of the market.

Roughly estimated, KNX probably costs around 10,000 euros, while a Homematic system is about 2,000 euros.
The manufacturer could go bankrupt five times before the KNX system pays off.
So, I only see the advantage of interchangeability to a limited extent here.

Eltako would also be significantly more affordable than Homematic.

Sure, if you have no idea what you’re doing, it can easily take 50-100 hours.

Rough estimates on this topic are about as reliable as a newspaper horoscope.
Come on, people, start comparing apples to apples.

Here is an example from another DIY enthusiast:

I have this contactor here:
.....
I plan to connect the Sonoff relay to A1, A2 and the binary input of the boiler thermostat relay at 1.2.

It turns out that there is no voltage at the binary input and there never will be.
Then I configure the Sonoff relay to switch on from 11 p.m. to 7 a.m. (circuit 1.2).

In the afternoon – I monitor the temperature at some point using the same relay (for example, the temperature at the boiler return line).
When the temperature falls below a certain value, I manually switch on the boiler during the day to “warm up.”

There are also “independent” Sonoff relays on the first and second floors of the house, which I use to monitor the overall temperature in the house.


When you read something like this, you can only throw your hands up in disbelief.
