This page describes the "property request" mechanism, as well as the message format used to interact with it.

Message Format

All messages on this endpoint are CBOR encoded.

Requests

Requests are maps, with one or more of the following keys:

• get: An array of property IDs to read
• set: A map containing properties to set. Keys in the map correspond to property IDs.

Replies

The device responds with a map, which contains the following keys. Which keys are included in the response depends on the request:

• get: A map (keyed by property IDs) containing the value of all requested properties. Any properties that were requested, but are not included in this map are not supported.
• set: An array containing the property IDs of all properties that were set. Any properties that were requested to be set, but are not supported (or read-only) will not be included.
