@Springrbua I disagree, the product was solid as a matter compatible energy meter smart plug, an average user would consider that would mean that energy meter functionality to be compatible with matter. A user should not need to understand that at the time of original product launch the matter protocol didn't support energy meters. And since the product is still be sold, and still being advertised as a matter compatible energy meter smart plug then it should support what it is advertising.

I bought mine yesterday, and well i'm happy with installing the tp-link intergration, i'm a little anonyed that i paid 5 dollars per plug more to get matter, and it doesn't support the functionality i wanted. And when i bought it matter did support energy meters (not that matters, what is advertised matters), so i was solid a defective product that doesn't meet it's advertised functionality.

This does leave a slightly sour taste in my mouth, in what is otherwise positive expericences with tp-link products.

  @lovely2 I absolutely understand you and I am in the same boat.
I absolutely don't want to defend TP-Links behaviour. What I am trying to say is that there seems to be a loophole in the Matter certification.
TP-Link got the certification at a time Matter did not support the energy monitoring. From that moment on thei are officially Matter compatible and they can advertise that.
Now Matter supports energy monitoring but unfortunately that does not mean, that the certification is now invalid.
I don't even know if for a Matter certification a full compatibility is needed or if I get a certification as soon as a singel feature is Matter compatible.

>This does leave a slightly sour taste in my mouth, in what is otherwise positive expericences with tp-link products.

Absolutely. Especially how they handle this request makes me think if I want to choose TP-Link for other devices in future.
I am okay with waiting for an update especially if a certification is needed but at least a little bit of communication would be nice...

The P110M has got the Matter 1.3 certification and it indeed includes the power and energy clusters. The firmware update will arrive eventually, hopefully sooner than later!

This is the CSA official site: https://csa-iot.org/csa_product/smart-wi-fi-power-strip-8/

Do not mind the title "power strip", the Product ID is 0x0108 which is the ID of the P110M.

It is still one of the very few brands to have Matter 1.3 certified smart plugs.

I finally got an answer from TP-Link support and Matter 1.3 should arrive in the next (quote) "1 or 1 month".

I guess this was a tipo and it should be 1 or 2 month but it seems like the update is on it's way.

  @Springrbua 1 + 1 = 11 months

  @DoinitSideways damn, didn't think about that... :D
