Using IPSO Smart Objects

While the LWM2M interface provides an application-layer standard for device management over CoAP, it lacks by itself object definitions for sensors and actuators. These are, however, provided by the IPSO Alliance. Some IPSO Smart Objects that we will use are presented in the following table. Notice that there is a slight overlap:

Object	IPSO Smart Object definition
3200	IPSO Digital Input
3201	IPSO Digital Output
3202	IPSO Analogue Input
3203	IPSO Analogue Output
3300	IPSO Generic Sensor
3301	IPSO Illuminance Sensor
3302	IPSO Presence Sensor
3306	IPSO Actuation
3320	IPSO Percentage
