// SwitchMote Moteino sample sketch with PIR motion sensor support
// *************************************************************************************************************
// Handles the single 5A relay SwitchMote, as well as the dual 10A relay SwitchMote2x10A
// SwitchMote is a highly integrated wireless AC switch controller based on Moteino
// https://lowpowerlab.com/switchmote
// *************************************************************************************************************
// This sketch will provide the essential features of SwitchMote:
// - wireless programming
// - accept ON/OFF commands from a Moteino gateway (format is BTNx:y commands where x={0,1,2}, y={0,1})
// - control the relay(s) to turn the AC load ON/OFF
// - control up to 6 LEDs and 3 buttons on front panel
// - SYNC feature allows out of box synchronization with other SwitchMotes
// ie - when a button is pressed on this SwitchMote it can trigger the press of a button on another SwitchMote
// so you can use a SwitchMote button to control a light/set of lights from remote locations
// this sketch allows up to 5 SYNCs but could be extended
// - Panasonic PIR motion sensor support in place of middle button
// This sketch may be extended to include integration with other LowPowerLab automation products, for instance to
// control the GarageMote from a button on the SwitchMote, etc.
