tellduslive-list-all-devices.js

// Node-RED function to
// a) list all Telldus devices (device = everything in Telldus Live except sensors)
//
// The code below relies on the following modules to be installed in the Node-RED environment, including being set up
// in the functionGlobalContext section of the Node-RED settings.js config file (see last section of http://nodered.org/docs/writing-functions.html page)
//
// a) Telldus-Live module (https://github.com/TheThingSystem/node-telldus-live)
//
//
// The function will fire one output message for each device it gets information about from Telldus Live.
// By default the device id and name is included in the messages, but this can be customised as needed.
//

// Define Telldus Live API credentials
var publicKey    = '<enter your public key here>'
