Controlling all the relays in the house with arduino?

Question

Arduino

Hello. In general, I am interested in how to make relay control through arduino, expensive and smart.
More specifically:
Tell me the relay that is installed in the shield, with the ability to control this relay through arduino.
I don't want blue relays that are controlled by arduino. And of course, so that they can withstand the load on the whole house.
Thank you!

As I understand it, you need a pulse relay on a din rail.
They are available with coil voltages from 12V DC to 230V AC.
Switched currents - up to 16 A. Enough to control any household load.
But you can't control it directly with arduino.
If you organize an additional 12 V power supply, then you can implement control through the PC817 optocoupler. Like for example here (Raspberry Pi):
