Listing all devices associated with a Telldus Live account
This function node will connect to the Telldus Live service, and from there download a list of all devices available for the user credentials being used.
A device in this context is anything that is not a sensor, typical devices are radio controlled (the Tellsticks are 433 MHz transceivers for sending commands to/reading data from devices and sensors) on/off switches, dimmers, doorbells etc.
One message will be fired for each device, including the device's id and its name.
To use the device, just hook up an injector and a debug node, configure the user credentials in the node and make sure the needed node.js lib is installed.
