Hello everyone,
I am currently planning the components for my smart home in a new build.
Thanks in advance
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?
Thanks in advance

Alessandro23 Nov 2020 11:53It can only work if an intelligent door handle is used, one that allows position detection. See the Hoppe EnOcean window handle. Unfortunately, something like this is not yet available for lift-and-slide doors.
You’re somewhat mistaken, even if your general approach is on the right track. The smart door handles are not necessary, although they can be used. However, they are not the only option.
Two simple door contacts are sufficient. These can represent the handle position just as well without physically interacting with the handle itself. In other words, there are solutions even for tilt-and-slide doors.
With a bit more logic, it’s also possible to track and predict human behavior and states, opening up various application possibilities.
The lockout automation is really a task for an apprentice. There are much more complex scenarios out there.

T_im_Norden23 Nov 2020 12:22And how exactly do the two door contacts detect the position of the handle?
The simplest digital technology. Pages 2-3 in any textbook.
You can represent 4 states using two input signals. Based on these states, you can determine the position of the handle.

What you make of this is up to each individual or their own creativity/imagination. For some, it might only be enough to indicate whether the door is open, but there is much more possible.
Just imagine if you added feedback elements or something similar, nested links, or even a storage option...
