Matter Glossary

This defines acronyms and terminology frequently mentioned and used throughout the Matter project repository that are not otherwise well defined before their use and introduction absent the Matter specification.

BCM :Basic Commissioning Method

Check-In Protocol :A specific protocol used by a Long Interval Time (LIT) Intermittently Connected Device (ICD) to notify the client device that they are temporarily available for communication.

CIP :Check-In Protocol

ECM :Enhanced Commissioning Method

Electric Vehicle Supply Equipment :The hardware and software that safely delivers electricity from the grid to an electric vehicle’s battery, essentially the “charging station” with its connectors, cables, and communication systems that manage power flow and ensure safety during the charging process.

EVSE :Electric Vehicle Supply Equipment

ICD :Intermittently Connected Device

Intermittently Connected Device :A device that enters a low-power sleep mode for periods of time to conserve battery life, and thus is not always reachable on the network.

LIT :Long Interval Time

Long Interval Time :A configuration for an Intermittently Connected Device (ICD) where the device sleeps for much longer intervals (that is, minutes or even hours).

MEI :Manufacturer Extensible Identifier

PAF :Public Action Frame

PCC :Pump Configuration and Control

PDC :Per-device Credentials

Public Action Frames :Wi-Fi Public Action Frames (PAFs) are IEEE 802.11 management frames (Category 4) used for unencrypted, public communication between stations (STAs) and Access Points (APs) without requiring prior association.

RVC :Robotic Vacuum Cleaner

Short Interval Time :A configuration for an Intermittently Connected Device (ICD) where the device’s polling interval is relatively short (that is, several seconds).

SIT :Short Interval Time

SMCO :Smoke and Carbon Monoxide

TCC :Temperature-controlled Cabinet

UAT :User Active Mode Trigger

User Active Mode Trigger :A feature used by an Intermittently Connected Device (ICD) that allows a user interaction (like pressing a button on a device) to immediately switch the ICD from Idle mode to Active mode, making it instantly responsive for a short period of time.
