Welcome to the second guide in reef-pi series.  

See the first part of this series here.

In this guide, we will be building a power controller that can turn on/off AC equipment in a variety of ways (on-demand, timers, macro etc). Think of it as an automated power strip. 

This guide assumes you have a working reef-pi installation, if not, start with the first guide

In the first guide, we have gone through setting up reef-pi on a Raspberry Pi and test the equipment logic using a simple LED. We'll use the same software configuration with ancillary electronics and parts to control real AC equipment (like fan, heater, pumps etc.)
