Hi James,

The presence detection property is to be used inside a Sensor Status message (see section 4.2.14, Mes Model Specification v1.1)

The format is defined in the section. The property ID is in the XML link that you pointed to.

Sensor Status has opcode 0x52.

Hi Hung Bui,

I am indeed interested in communicating that there is a person inside a room.
Obviously if I define my own model and opcode and parameters I can have something working for myself, but I was wondering if there was a spec for that already. That is, what opcodes to use and what the parameters look like, similar to the Generic OnOff Model.

Hi James,

The "presence detection" you mentioned is used for detecting if there is a person inside a room for example.

Is it that what you want to do ? Or you want to detect the presence of the mesh node ? that it's active in the mesh network ?

If it's the latter, you should use the "heart beat" for the purpose. You can read more about heartbeat at section 3.6.7 in the Mesh profile specification v1.1
