Matter On/Off Plug-in Unit - Controller UI Display Issue

[Jang-woo-AnnaSoft]

Hi,

We are developing a Matter-certified device using the On/Off Plug-In Unit device type (0x010A).

The device commissions and operates correctly across major Matter controllers (Home Assistant, Google Home, Apple Home). However, we are facing a product launch blocker related to UI representation.

Every controller renders this device type as a generic "Switch" with a toggle icon, driven entirely by the Device Type ID — regardless of ProductName, NodeLabel, or userLabel settings.

This creates two concerns:

1. Branding — The "switch" representation does not reflect the device's actual function or intended user interaction.

2. Safety — Users may treat it as a standard switch and operate it at inappropriate times, which is a real safety concern for our specific use case.

Our questions (focused on what the Matter specification allows):

• Does the Matter specification provide any mechanism — beyond Device Type ID — that a manufacturer can use to influence how controllers render a device in their UI?
• Is there a more suitable device type for a device that exposes On/Off functionality but is not intended to be used as a general-purpose switch or plug?
• Are there any plans in the roadmap to introduce finer-grained UI hints or device sub-types within the spec?

We want to stay fully spec-compliant, so we are looking for what is formally supported within the Matter standard rather than controller-specific workarounds.

Any guidance from the spec or SDK maintainers would be greatly appreciated.

Thank you!

Hi there,

Thank you for reaching out with your Matter device implementation question.

For technical implementation guidance and support related to Matter device certification, UI representation, and device type specifications, I recommend creating a support case through our Contact Us portal: https://developer.amazon.com/alexa/console/contact-us

When submitting your case, please include:

• Your device type (On/Off Plug-In Unit - 0x010A)
• Specific details about your intended use case and why the standard "switch" representation creates safety concerns
• Any relevant certification details or product information/ test details

Our support team will be able to provide more targeted guidance on this query. You should get much better traction on this issue through a formal support case, as the team can work directly with you on implementation details and potentially escalate to the appropriate product teams if needed.

Best of luck with your product launch!
