MQTT

The “mqtt” plugin is an extended version of the “sensor” plugin that provides MQTT protocol functionality. Here are some settings available for the “mqtt” plugin:

1. subscribe_topic: The MQTT topic to subscribe to for receiving data.
2. mqtt_login: The login for authentication when connecting to the MQTT broker.
3. mqtt_pass: The password for authentication when connecting to the MQTT broker.

These settings allow you to specify the connection parameters for the MQTT broker and define the topic to subscribe to for receiving data. Thus, the “mqtt” plugin enables integration with MQTT messages, allowing you to receive data from devices using this protocol and use them in automation systems or other components.

The “sensor” plugin also implements a JavaScript handler called entityAction. This handler is designed to process actions related to “entity” type devices based on the “sensor” plugin.

Here’s an example implementation of the entityAction handler:

entityAction = (entityId, actionName, args) => {
  // Action handling code
};

It also implements a JavaScript handler called mqttEvent. This handler is designed to process actions related to “entity” type devices based on the “sensor” plugin.

Here’s an example implementation of the mqttEvent handler:

function mqttEvent(message) {
  // Action handling code
};

Example usage of the mqttEvent handler:

mqttEvent =(message)->
  #print '---mqtt new event from plug---'
  if !message || message.topic.includes('/set')
    return
  payload = unmarshal message.payload
  attrs =
    'consumption': payload.consumption
    'linkquality': payload.linkquality
    'power': payload.power
    'state': payload.state
    'temperature': payload.temperature
    'voltage': payload.voltage
  EntitySetState ENTITY_ID,
    'new_state': payload.state
    'attribute_values': attrs
