## Article

In the **Pi-Home** project, you can use any standard buttons and switches for 230 V or special ones for 24 V or 12V. In smart homes, instead of switches (classic off/on positions) the **buttons are preferred** (return to original position after pressing) . The reason is obvious, we can attach more different functions to the button (repeated pressing, holding, etc). In our realizations we have a very good experience with classic 230V buttons from **Hager/Berker**, but of course it is possible to use any other brands.

### **What we'll need**

[Part 2 - OpenHAB na Raspberry Pi](https://opentux.eu/solutions/smart-home/how-to/openhab-raspberry-pi-guide)

230V buttons - design is up to you, Hager/Berker recommended

Arduino Mega with Ethernet Shield (DIN holder)

Krone LSA terminals
