• enabled: Boolean Sensor is enabled or not. (default = false)
• debug: Boolean enable/disable logging to Xcode console. (default = false)
• label: String Label for the data. (default = "")
• deviceId: String Id of the device that will be associated with the events and the sensor. (default = "")
• dbEncryptionKey Encryption key for the database. (default = null)
• dbType: Engine Which db engine to use for saving data. (default = Engine.DatabaseType.NONE)
• dbPath: String Path of the database. (default = "aware_openweather")
• dbHost: String Host for syncing the database. (default = null)

• OpenWeatherSensor.ACTION_AWARE_OPENWEATHER_STOP: received broadcast to stop the sensor.
• OpenWeatherSensor.ACTION_AWARE_OPENWEATHER_SYNC: received broadcast to send sync attempt to the host.
• OpenWeatherSensor.ACTION_AWARE_OPENWEATHER_SET_LABEL: received broadcast to set the data label. Label is expected in the OpenWeatherSensor.EXTRA_LABEL field of the intent extras.
