5: INFO       - consloe.log ( Default )
7: DEBUG   - consloe.debug
8: TRACE    - consloe.trace

Plugin

  1. Rename the pluginClassTemp.js  by your applicaton name
  2. Chang the plugin path in index_plugin.js : var agentplugin = require('./module/pluginClassTest.js');
  3. InitPlugin: InitPlugin  => Refer < InitTest > in pluginClassTest.js
  4. AutoReport: start auto report callback function by interval; To implement send data in this function=> Refer < AutoUpdateTest > in  Simple-plugin_test.js
  5. setSenseData: DeviceOn server or other apps to set sensor value to the service. This callback function will be called and you need to implement a set function with your application at this.
  6. sendEvent: You can refer to "sendEventTest" in pluginClassTest.js to trigger an event alarm to the local MQTT Broker and transfer to DeviceOn server.

Note

  • If the plugin needs to send OPTS to DeviceOn, OPTS can not be assigned to 0 in plugin's capability. OPTS must set timestamps according to your application.
