Getting Started

This section is still work in progress.

Plugin Configuration

While run MQTT broker on localhost and on a standard port, without autentification, you can load the plugin by editing your config.json to include the following in the plugins section.

{
  "plugin": "mqtt",
  "active": true,
  "brokers": [
    {
      "brokerId": "default"
    }
  ]
}

Configuration with two Brokers

{
  "plugin": "mqtt",
  "active": true,
  "brokers": [
    {
      "brokerId": "default"
      "host": "localhost"
    },
    {
      "brokerId": "eclipse",
      "host": "iot.eclipse.org"
    }
  ]
}

The configuration for a broker is an object comprising the following properties.

Device Configuration

Devices must be added manually to the device section of your pimatic config.

Generic sensor

MqttSensor is based on the Sensor device class. Handles numeric and text data from the payload.

Rules

You can publish mqtt messages in rules with the action:

publish mqtt message "<string with variables>" on topic "<string with variables>" [on broker ListOfBrokers] [qos: 0|1|2] [retain: true|false]

"rules": [
  {
    "id": "my-rule",
    "rule": "when every 3 seconds then publish mqtt message \"msg\" on topic \"topic\" on broker default qos: 1 retain: true",
    "active": true,
    "logging": false,
    "name": "Publish mqtt"
  }
]

You can trigger rules by mqtt messages with the predicate:

mqtt received "<message>" on topic "<topic>" [via broker ListOfBrokers] [qos: 0|1|2]

"rules": [
  {
    "id": "my-rule-2",
    "name": "Receive mqtt",
    "rule": "when mqtt received \"1\" on topic \"topic\" via broker default qos: 0 then log \"Yeah!\"",
    "active": true,
    "logging": true
  }
]
