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 should forget about trying to control underfloor heating.

Because the thermostats should always be left open, or ideally not installed at all. They undermine the efficiency of your heating system. Additionally, any adjustments would only become apparent after about half a day since underfloor heating systems are very slow to respond, making it practically impossible to control them this way.

Of course, it is slow to respond, but there are rooms that should be warmer or cooler.
However, that was not my original question.

Of course, but you don't need thermostats for that. It’s done through hydraulic balancing. Thermostats just damage your heat pump... Look on the bright side, it saves money.

I meant more like on or made of.
The volume flow is, of course, set firmly.
