Tuya’s Matter solution helps you get your product Matter-certified with less overhead and short time-to-market in order to get the most out of the Matter ecosystem. With a suite of Matter solutions, you can also integrate with big platforms like Apple Home, Samsung SmartThings, Amazon Alexa, and Google Home at the same time. As of November 2022, the Thread-based smart lighting products and Wi-Fi based smart sockets and lighting products, and wired gateways get Matter certified.
This topic describes what Matter is and information about Matter certification.
Matter, introduced by Connectivity Standards Alliance (CSA) in 2021, is a standard for the application layer. Amazon, Google, and Apple have all announced that their smart home ecosystem Alexa, Google Assistant, and HomeKit will be compatible with Matter. The Matter 1.0 standard has been officially released by CSA in October 2022.
Matter is a unifying, IP-based connectivity protocol built on proven technologies such as Wi-Fi, Bluetooth, and Ethernet.
Matter aims to reduce fragmentation in the smart device market with an industry-unifying standard. It allows all smart home devices to work with each other over a local network, regardless of the brand.
CSA classifies two types of products that can apply for Matter certification.
|Hardware Device Certification||A Matter hardware device refers to hardware that can provide capabilities of a Mater device type, which applies to both end products and modules with complete functionality. For example, sensors, switches, refrigerators, and lighting.|
|Software Component Certification||A Matter software component refers to software that runs on an operating system supported by CSA (such as TVs, mobile phones, and Raspberry Pi). For example, apps and OTA providers.|
A single Matter device can be integrated with both product types and applies for both Hardware Device Certification and Software Component Certification. For example, TVs and central controls.
Request a vendor ID.
Develop a product using Tuya’s Matter solution.
Select network transport.
Check if the vendor has obtained certification for its wireless solution from relevant organizations, such as Wi-Fi Alliance, Bluetooth Qualification Body, and Thread Group. A physical layer self-test report is required for the network interface. For more information, see What should I prepare to apply for Matter certification for end products?
Select a CSA-authorized Tuya partner lab to have your product tested. Your test provider will submit the final test result to CSA.
Before submitting your application, be sure to have these documents ready: Declaration of Conformity (DoC), Protocol Implementation Conformance Statement (PICS), Network Transport Attestation, and Security Attestation.
CSA reviews your application. After your product certification is approved, you will receive a formal certificate. Only Matter-certified devices can carry the Matter logo.
CSA enters the certified product in the Distributed Compliance Ledger (DCL). Certified products can be found at CSA website.

Smart products involved in Matter internal testing (including the TEX and SVE stages) can get a pre-certification for Matter.
To apply for Matter certification, your company or organization must be a CSA member. If you join CSA as a member of Zigbee Alliance, you still enjoy the benefits applicable to your membership level.
There are four types of membership categories at the CSA:
|Standard certification||Not eligible||3,000||2,000||2,000|
|Certification by similarity||Not eligible||2,500||1,500||1,500|
|Certified product listing on the Alliance website||500/Year/Model||0||0||0|
|Re-certify a product family||Not eligible||8,000||4,000||4,000|
|Extend a product family||Not eligible||1,000||500||500|
There are no annual fees for Associate membership. An Associate member is eligible to receive a certification transfer and is not eligible for product testing and certification application. For more information, visit CSA website.
The following description applies to Zigbee and Matter certification:
|Standard Certification (Testing)||Certifies a single product.|
|Certification by Similarity||Allows a product that is derived from a previously certified product to be considered for certification based on its similarity to this certified product depending on the differences between the two.|
|Certification Transfer Program||Enables Alliance Participants and Promoters to offer their certified products to customers for re-branding/white labeling while maintaining the certified status of those products.|
|Product Family Certification||Certifies a product family, including multiple family member products of the family on a single certification application, based on the parent product within the family. The differences between the variants must not affect the conformance of the family member products to Alliance Specifications. For example, family member products with different regional power plug variants. Certification fees:
Certification Transfer Program and Product Family Certification Program do not apply to mobile apps.

Matter recognizes the following communication protocols. The chips, modules, or end products that use these protocols should get certified by the relevant standards organization.
|Bluetooth SIG||Bluetooth Low Energy (LE) v4.0 or later.|
|Ethernet Compliance||A self-test report for IEEE Physical Medium Attachment (PMA).|
|Wi-Fi Alliance||Wi-Fi 4 (IEEE 802.11n) or later.|
|Thread Group||Thread 1.3.0|
Dependent Certification Program (DCP) is launched for Matter hardware certification to denote communication layer support for Matter implementation.
During the process of Matter implementation, be sure not to modify the DCP-certified chips and modules so that the end products integrated with the certified hardware can inherit the certification to apply for Matter certification.

CSA does not support module-based certification transfer.
If your end product uses the hardware design solution and software that is identical to Tuya’s Matter-certified products, including:
You can apply for a certification transfer and make a change to the product enclosure. If you have fine-tuned hardware, check with CSA to see if you can apply for certification by similarity first and then do a certification transfer.
Matter is an application layer protocol, so take care of the followings:
The wireless solution that your end product uses should be certified by the relevant standards organization, such as Wi-Fi Alliance, Bluetooth SIG, and Thread Group. Search for the certified products:
