MQTT

Communcation with things happens over MQTT. This program basically hogs onto an existing MQTT server.

Topics

iot/hello

All things need to annouce themselves and give information about themselves in JSON:

{
    uid: "example-lamp", // The unique ID for the thing (only use url friendly characters)
    props: { onOff: "boolean", rangeExample: "0-100" }, // An object with the prop name as key and accepted input as value (boolean/string/number/[min]-[max])
    name: "Example Lamp", // The name of the thing (default: "Unnamed")
    mainProp: "onOff", // If you have a boolean prop that should be clickable from the dashboard (default: "")
    icon: "lamp" // What icon the thing should have (default: "")
}

iot/[uid]/config

Whenever a thing publishes to iot/hello, we respond with the current states of the different props on this topic in the form [prop]:[value]

iot/[uid]/recv

Where things receive data like lamp:false

iot/[uid]/send

Where things send data like lamp:true
