check the internet more often please before claiming something doesn't exist. I have discovered months ago that Matter 1.3 plugs exist since it works fine on HA using matter. To be fair, I belive tp-link/tapo creates a lot better products than generic tuya rebrand stuff so I am waiting for this too. I have the regular P110 non M and I prefer using these smartplugs the most over others. And I look forward to buying some P110Ms once the new firmware proper is out.

  @Wayne-TP Hi Wayne.  I'm wanting to use the P110M plugs with my Homey Pro. Homey Pro are working with Eve, so it might be a good time to engage with them.  See https://community.homey.app/t/matter-1-3-specification-released-will-power-monitoring-now-be-supported-by-homey/115197 

Also here making a decision for buying a smart plug. Having one TAPO 110M, but will not be buying more until there is a resolution from TP-LINK to enable energy monitoring via Matter.

  @Cammm 

I would like to buy more plugs. Is there a specific timeframe for when that will be available?  A response like "stay tuned!" doesn't really satisfy me. 

@mgguinne To be fair there are no Matter 1.3 smart plugs in the market right now. The Eve Energy is certified but does not have the firmware update yet, people who can see the energy consumption of the Eve in HA or SmartThings is because they use a non-standard attribute and those two platforms included Eve-specific code to read it (not the way to go to avoid fragmentation but the standard was lacking that feature until 1.3 and they're migrating to use the standard now).

In the short term it's going to be a feature that will greatly impact purchase decisions because it allows not just to watch the consumption but run automations, it's much more powerful. I'm sure TP-Link will eventually include it, the question is how long it will take.

  @Cammm Following this thread. Holding off buying any of the P110M units until Matter 1.3 supported firmware to allow power monitoring in Home Assistant. Honestly the only reason I would buy them. Any updates from TP-Link on when this firmware will be updated?

This needs to happen; it's in the matter standard, and other manufacturers have this. I have bought a lot of TP-link products and love them. Let's update the software to align with your competitors so I don't have to buy their stuff.

Voting for the feature, SmartThings is already beta testing the new firmware with Matter 1.3 support and the github branch for Matter 1.3 drivers already supports the new energy clusters.
