I wanted an irrigation controller to replace the old "mystery box" (the first pic) crammed with relays, timers and wires, installed by one of the previous homeowners. It should be Z-wave controllable of course, but also with the ability to control stuff locally via pushbuttons, and with LED indicators. It controls 220v lights and pumps, 12v lights, and 24v valves.
This is what I built out of 4 Fibaro switches and some elbow grease
(The capacitors and diodes on the PCB are to drive the LEDs directly off 220v/24v AC)
