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

Because the thermostats should always be fully open, or better yet, none should be installed. They ruin the efficiency of your heating system. Also, with underfloor heating being very slow to respond, you wouldn’t notice any changes until half a day later, making it practically impossible to control.

This is how we have it with our Novelan system as well.
There are actuators and heating valves installed on each floor, but they are not used. The heating system regulates the temperature throughout the whole house at a fixed setpoint.
It’s very comfortable and cozy in every room.

I wouldn’t know how to implement that with a traditional sliding door. Do you have any ideas? Where could I place a second contact there?

This is how it works with our sliding door. The contact switches immediately to "open" as soon as the handle is unlocked, even if the sliding door doesn’t move at all.
It’s the same with standard doors. Handle down = closed, anything else means open.

Yes, that makes perfect sense. With only one contact, you can represent just 1 and 0. An additional contact provides two more states. In other words, it allows differentiation between being open but closed against something, and being fully or partially open.

Where is the contact located on your door? In the handle or the frame?

If that is the contact point, then it is at the very top of the door and frame.

And does it really only detect the handle being operated? Well, the door is slightly lifted or lowered in the process. I wouldn’t have thought that would be enough.
