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

I pay about 2000 euros for my Homematic system. Please explain how I could get cheaper with KNX?

Included are:
Actuators for roller shutters
Smoke detectors
Actuators for sockets and heating units
Multiswitch
Smoke detectors
Motion detectors

Without a specification sheet, comparison is meaningless. You have listed the smoke detectors twice.

Just as a side note: last month, I installed a small off-grid system for a client with a total of 50 switching points. The cost was 1600 euros.

Of course, you need to compare it with the specification sheet.

Otherwise, I would like to commission you directly, as my KNX quotes ranged between 10,000 and 20,000.

Compare the component prices. KNX is cheaper than Homematic.
Doing it yourself and having it done by others cannot really be compared.

Now, setting aside the prices charged for the individual systems, each system has its advantages and disadvantages.

I think many people lose interest as soon as the word programming comes up. Even though much of it can actually be managed with very simple logic.

If I imagine having to call someone every time I want a change in the programming or to extend the functionality, I would be just an average consumer out. They would rather buy some smart light bulbs they can control with their smartphone (which has to be smart—that’s obvious from the name :-)).

I have to say that I’m quite a fan of my Homematic system. However, because of the prices of Homematic components, I also use other systems, which I control through Homematic software. In my opinion, this gives you a pretty powerful tool.

Of course, I try out many things there, where, for example, my neighbor (the same age) just shakes his head and asks what I would have done with my life without the house. ;-)

But you can’t blame people—watching an unboxing video of a new smartphone is obviously more fun than diving deeper into the topic of home automation.

This is also a relic from the 1990s; usually, no actual programming is done. At least not for a standard house with a manageable number of components. Functions are pieced together using dropdown menus, and devices are linked by drag-and-drop.

Yes, in the end, you have to press the "program" button. But it essentially just transfers the changed settings.

Also, there is no need to call in a technician anymore. Either the tech-savvy homeowner does it themselves, or the system is maintained remotely.
