Support Matter Closure Devices

[lboue]

Describe the enhancement

In Matter, "closure" refers to a device type that controls physical barriers or access points, such as:

• Doors (garage doors, gates)
• Windows (smart blinds, shutters)

These devices are standardized under the "Window Covering" device types in Matter, but the term "closure" is sometimes used informally to describe any device that opens, closes, or locks something.

For closure devices, Matter 1.5 may offer:

• More granular control (e.g., partial opening/closing)

Control Matter Closure Devices from Home Assistant

Anything else?

An example of a Closure as a standalone device type is illustrated below.

In Matter 1.5, the ClosureControl and ClosureDimension clusters are key components of the new, unified "Closures" device type, which standardizes how smart home devices like window shades, garage doors, gates, and awnings are controlled and monitored. Here’s a breakdown of each cluster:

---

ClosureControl Cluster

• Purpose: This cluster provides commands and attributes for controlling the movement and position of closure devices (e.g., opening, closing, stopping, or setting a specific position).
• Key Features:
  • Supports commands like Open, Close, Stop, and GoToPosition.
  • Allows for precise control of devices with different movement types (sliding, rotating, swinging).
  • Enables real-time status updates (e.g., current position, movement state).
• Use Case: Ideal for devices requiring direct user control, such as motorized blinds, garage doors, or gates.

---

ClosureDimension Cluster

• Purpose: This cluster defines the physical dimensions and configuration of closure devices, such as the number of panels, their arrangement, and their movement capabilities.
• Key Features:
  • Describes the structure of the closure (e.g., single panel, dual panel, nested mechanisms).
  • Supports attributes for panel size, orientation, and movement type (e.g., sliding, tilting).
  • Allows for complex configurations, such as multi-panel window coverings or segmented awnings.
• Use Case: Used to represent the physical layout and capabilities of a closure device, enabling apps and ecosystems to understand and interact with the device appropriately.

How They Work Together

• ClosureControl handles the operational aspects (what the device does).

• ClosureDimension describes the physical aspects (what the device is).

• Together, they enable a modular, flexible approach to supporting a wide range of closure devices, from simple blinds to complex multi-panel systems.

A new version of the SDK at SilLabs: Silicon Labs Matter Version 2.8.0-1.5 (Jan 22, 2026):

• Added Closure App for Thread and Wi-Fi (SiWG917 SoC).
• Matter EFR32 Closure Example

This release is certifiable to the Connectivity Standards Alliance (CSA) Matter 1.5 certification program

So I can test the future implementation with this device.
