heating.be Function returns only amount of relays defined on pins. To work properly with 74hc595 and other hardware which is creating "power" devices change line to: return 6 (amount of your power devices to use)

static def get_relay_count() def pin(t, enum) while gpio.pin(enum, t) != -1 t+=1 end return t end return pin(0, gpio.REL1) + pin(0, gpio.REL1_INV) end
