Just to self-answer myself, the matter specifications have two new clusters for energy, 0x0090 and 0x0091. Neither are exposed after updating to Firmware 1.2.3, so I guess we will just have to wait :(

Firmware 1.2.3 Build 240617 Rel. 153525 Doesn't appear to be any specifics about matter in the very limited release notes, but the lack of specifics in the release notes still leaves a possibility....

I noticed there was a firmware update this week for the P110M, but the notes doesn't mention any matter related updates. Can TP-Link confirm if this update has any changes for Matter 1.3?

@Wayne-TP thanks, I'm integrating with home assistant which has matter 1.3 support now, so I am eagerly awaiting the new firmware.

With the new matter 1.3 support being released containing support for energy monitoring devices like the P110M, when will we see the firmware update support for the new matter standard? I assume that...
