Presence Sensor Rest Stack Example

This example uses a very simple REST Stack to manage some presence sensors (PIRI1 to PIRI5 and CAM1 to CAM5).

Supported operations are

• list all sensors
• attach a sensor (use it to detect presence)
• detach a sensor (don't use it anymore)
• show attach date and last detected presence for a single sensor
• show attach date and last detected presence for all sensors

Example
