@MarkCarline They just have outdated information:

 

• Home Assistant supports it since version 2024.10, it was even explicitly announced (won't let me link it) that you could use smart plugs with Matter 1.3 energy monitoring in the energy dashboard and they tested the feature with another brand.
• SmartThings, also in early October, updated the stock Edge drivers that handle Matter smart plugs to account for the standard power measurement attribute of Matter 1.3. For anyone interested the source code is here and you can see it subscribes to the ActivePower attribute and exposes the value to the platform to use in the user interface or automations.

 

These two platforms expose the energy data to the user and if Tapo launched the firmware update it would work as expected in them.

 

Then there are platforms that internally support it but only for developers, like Google Home for instance. The platform is certified for Matter 1.3 and the Google Home API supports the active power attribute, but it is not exposed to the user and cannot be used in automations either until they create a user interface for that and add support in the automation engine.

 

Would be so good to get this

  @Wayne-TP this holding back because of home assistant is seriously, seriously short sighted. Home assistant is an open source community, and can't develop support for something without a device that exposes the right attributes. (No one has access to pre-release hardware

 

i guarantee you, the nanosecond you release firmware, someone will update to support.

  @Cammm agree 10000%  We could have a bug report / development request open within minutes ;)

 

@Wayne-TP Happy to test

@Cammm Mind that Matter energy reporting is a standard: there's no development needed for Tapo to support specific smart home platforms or support in smart home platforms for specific vendors like Tapo. It would be very very wrong if Home Assistant or SmartThings had to add specific code for Tapo when they support the standard.

 

The active power reporting attribute is perfectly defined in Matter spec and it's so simple: it's just the measurement in milliwatts. It's the same subscription mechanism used to report the brightness level of a bulb or the temperature of a sensor. The only care needed by Tapo is being a bit smart when emitting a report so it's meaningful and fast when a change in power consumption happens and doesn't flood the Matter controller with reports when the power hasn't changed much.

 

Also, again, both SmartThings and Home Assistant do support it so it should work as long as they comply with the standard.

  @Wayne-TP my issue is that currently the box is misleading.

 

it is saying it is a matter device with power monitoring. Yet you say here that it's firmware doesn't support power monitoring over matter.

 

i feel very let down and just another TPLINK advertising garbage. Is this going to be like the lack of web GUI for the Deco units? I'm sure that request has hundreds of upvotes... yet is just ignored by TPLink...

Release this update asap. I bought the unit because the box lists matter protocol and power monitoring, without highlighting it’s one or the other.

I am sure TP-Link will be giving us a firmware update before the end of the year.

 

After all - the competitor (Meross) has a beta firmware which people seem to be able to get via support which is working with energy monitoring and HA, see:

 

https://community.home-assistant.io/t/meross-mss315-and-matter-1-3-matter-server-v6/738089/37

 @MarkCarline you had me excited about the meros!
 

But, the one and only advantage that TP-Link have at the moment is the slim design (you can fit two P110Ms in an Australian double socket side by side).
 

I really don't like the TP-Link as a brand and this experience just re-enforces that. I've got 6 plugs which are sitting in their box. I'll happily jump ship as soon as there's a matter plug that can be used in a double PowerPoint.
