Data from Matter Server to sensors

Hello, I recently got an outlet that supports Matter. It works in its own ecosystem (Yandex), and there it shows energy consumption data. Being swiped into Home Assistant or HomeKit, I can’t see the data.

But through the Python Matter Server add-on, I can see my socket, nodes, endpoints. Current, voltage, instantaneous power values. But I can’t figure out how I can throw this data into the sensors so that it goes into the statistics. Can you tell me?

Is it possible to do with Home Assistant, add-ons and integrations, or will I have to code?

I don’t have one of these devices, but try to help…
If you go to UI->Systems->Devices&Services Integrations->Matter and click on “x Devices” (x is the number of devices), do you see your Yandex? If yes, then click on it and do you see your current/voltage/power under Diagnostics? Starting 2024.10, HA supports Matter 1.3 Energy/Power clusters.
If yes, then there should be a corresponding sensor entity for each.

Also, in your last figure, there are a couple of “Custom/Unknown Cluster” which likely means only the App knows how to read these.

Hm, it seems the device supports the ElectricalMeasurement Cluster which we do support in Home Assistant nowadays :thinking: So you just don’t see any electrical measurement in the Home Assistant device page?

Can you share the diagnostic output (three dot menu, “Download diagnostics” on the device page).

Unfortunately, that’s all I see on the page is what’s in the screenshot.The values aren’t there. If there were, I could have handled it myself =)

Yes, they are there, but when it comes to values, what I need is RmsVoltage, RmsCurrent, ActivePower with specific divisors or multipliers.

Yes. I can see these values in the Yandex Smart Home app - and it doesn’t matter if I’m add a device into it from Apple HomeKit, or if the Yandex Smart Home app is the original one where I plug in the outlet. But nothing else interprets them, as I understand it.

Of course. I download file to 18.6 KB file on MEGA
