Adding security features to the Smart Home application

We have already added the Philio multisensor to our system to read illumination and temperature values. Let's add a flood detector to the Aeon USB controller; and as you have in previous chapters, follow inclusion instructions from its manual. Then we can start the required implementation in the application.

Before proceeding to work with security sensors, we need to define sensor types and command classes to identify messages.

The following commands are used to report sensor changes:

Sensor type	Message sent	Report value
Binary sensor	COMMAND_CLASS_BINARY_SENSOR, 0x30	BINARY_REPORT, 0x03
Sensor alarm	COMMAND_CLASS_SENSOR_ALARM, 0x9C	SENSOR_ALARM_REPORT, 0x02

These constants have been defined in the message.h file, as shown here:

#define FloodSensorNodeID    0x05

enum BINARY_SENSOR_TYPE {
  GENERAL_PURPOSE = 0x01,
  WATER_DETECTION_SENSOR = 0x06,
  TAMPER_SENSOR = 0x08,
  DOOR_WINDOW_SENSOR = 0x0A,
  MOTION_DETECTION_SENSOR = 0x0C...
