node-red-contrib-rainbird/rainbird-startProgram.js

Node-RED nodes for controlling RainBird sprinkler controller (like: ESP-ME3) via local LNK2 wifi module connection. This wraps the RainBird SIP protocol using AES encryption. It uses a slightly modified version of node-rainbird originally developed by @bb
