Provisional means that something is not certifiable at this stage.</p> <p>The cluster is no longer provisional in Matter 1.4.2, so if you want to use Scenes Management and certify it, you should use nRF Connect SDK v3.1.0 or later, which uses Matter 1.4.2.</p> <p>The developers recommend creating an issue in the connectedhomeip repository:&nbsp;<a href="https://github.com/project-chip/connectedhomeip/">https://github.com/project-chip/connectedhomeip/</a>.</p> <p>Best regards,<br />Marte</p><div style="clear:both;"></div>RE: Inquiry About Matter Certification Test Failure on TC-S-2.2, Step 8ghttps://devzone.nordicsemi.com/thread/551469?ContentTypeID=1Tue, 14 Oct 2025 14:57:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d2a2f920-4ef1-4ce6-9f29-81ecc5a21dfeMarte Myrvold<p>Hi,</p> <p>I have reported this internally and am waiting for a response from the developers.
