Another node type is now available on the Gateway automation interface: a sprinkler controller. This is achievable through a board I designed to be able to control many outputs. I call this board IOShield and it features two 74HC595 serial to parallel shift registers.
The IOShields are daisy chainable and can take 24VAC through a buck regulator. Wireless control is done with a regular Moteino or MoteinoUSB and in a daisy chain only the first board would need the regulator and Moteino.
