To be honest, I don’t know which Matter version is installed on the Plug S MTR Gen3. I can’t find any reliable information on this.

As @mluecke already mentioned, acc. to CSA the Shelly Plug S MTR Gen3 is using the Matter specification v1.2:

([Source](https://csa-iot.org/csa_product/shelly-plug-s-mtr-gen3/))

But the info about the Matter version refers to the Shelly firmware **v1.2.0-s1** and my plug has a newer firmware **v1.2.3** installed.

I can’t find any detailed information about the Matter version on the Shelly support pages, not even on the by @SunBeech mentioned [changelog](https://shelly-api-docs.shelly.cloud/gen2/changelog/#123-2024-02-28) page. When I open the linked page regarding **Matter** , it shows only something about version 1.0:

Another page states this:

([Source](https://support.shelly.cloud/en/support/solutions/articles/103000060376-do-you-support-matter-))

So it seems that Shelly doesn’t provide detailed information about Matter, or I haven’t been able to find it. Nevertheless, the reason for the missing energy data will most likely be an “old” Matter version. 🤷‍♂️
