PART 5 - CONTROL POWER CIRCUITS (LIGHTS, SOCKETS, HEATING) (OpenTUX Pi-Home)
Switching power circuits - sockets, lights, blinds, pumps and other devices under 110-230V is one of the essential functions

Switching power circuits - sockets, lights, blinds, pumps and other devices under 110-230V is one of the essential functions of an intelligent house. At Pi-Home, we are using Arduino Mega boards with Ethernet Shield, which control Arduino's compatible SSR relays connected with high power relays of the switchboard.
What we'll need
Part 2 - OpenHAB na Raspberry Pi
Arduino Mega with Ethernet Shield (DIN holder)
Arduino SSR relay 8x2A/230V (DIN holder)
Installation relay ie EATON Z-R230/S or multiphase EATON Z-R230/4S
DC Power Source 5V 40W (DIN)
