It is interesting that for my application I get different results than in the power consumption reference if I use the SSED settings.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I&amp;#39;m using a Google Nest Display as thread border router for my tests. Can it be that it is using CSL parameters that are not working well for a SSED? Is it possible to&amp;nbsp;debug this somewhere?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Thread: Higher power consumption with SSED compared to SED</title><link>https://devzone.nordicsemi.com/thread/543221?ContentTypeID=1</link><pubDate>Tue, 22 Jul 2025 14:34:57 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:11fc9e79-7219-45a6-80a9-502f3fb00063</guid><dc:creator>dejans</dc:creator><description>&lt;p&gt;Hi,&lt;br /&gt;&lt;br /&gt;You can look at the&amp;nbsp;&lt;a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/thread/sed_ssed.html#comparison_of_sed_and_ssed"&gt;SED and SSED comparison&lt;/a&gt;&amp;nbsp;which provides information when to use SSED.
