IOTDB Transporter for MQTT
About
This Transporter will transport data from and to MQTT. Note that reading
commands like list
, get
, bands
are meaningless as data only exists
when it shows up on the wire: this Transport does not retain anything.
Use
See the samples folder for working examples
Broadcasting
Get another transporter as a "source" - typically this will be IOTDB. In this particular example, we will connect to a WeMoSocket on the network.
const iotdb = require("iotdb");
iotdb.use("homestar-wemo");
const things = iotdb.connect("WeMoSocket");
const iotdb_transport = require("iotdb-transport-iotdb");
const iotdb_transporter = iotdb_transport.make({}, things);
Create a MQTT client instance. We provide a helper for this.
const mqtt_transport = require("iotdb-transport-mqtt");
const mqtt_client = mqtt_transport.connect({
host: "mqtt.iotdb.org",
verbose: true,
}, (error, mqtt_client) => {
if (error) {
return console.log("#", _.error.message(error));
}
})
Then we create a MQTT Transporter using the client.
const mqtt_transporter = mqtt_transport.make({
prefix: "things",
}, mqtt_client);
Then we tell the MQTT Transporter to get all the data from the IOTDB Transporter.
mqtt_transporter.use(iotdb_transporter)
That's it - we are operational. If you go to mqtt://mqtt.iotdb.org/things you will see all changes to your things being broadcasted.
Receiving
If you'd like to be able to control IOTDB from MQTT - we don't recommend this because there isn't a good security model here yet - just add this
iotdb_transporter.use(mqtt_transporter)
