2025.12 Energy config: Adding a group with only a Power entity as an individual device.

[wicked oriole]

All my lights expose the Power entity but not an Energy one. I've grouped all of them into an "All lights: Power" group that shows up nicely on the Energy Dashboard config individial devices.

From there, I don't quite understand why an Energy sensor is required if I have a Power one (that HA is tracking in time).

In any case, I am trying to figure out how to create an entity that measures all that Power over time (Wh) to add to the Energy dropdown in the config . (BTW, note that in Spanish the labels for both Power and Energy are the same: "Consumo de energía del dispositivo")

I though that, by creating an Utility meter helper using the Power sensor over time will work, but it doesn't. It doesn't show up on the Energy dropdown on the Energy Dashboard config.

Any tips about how to add the "All lights" group on the Energy Dashboard?

I guess it's just partially an oversight, and a legacy behavior from when there was only energy (and of course it would not make sense to add a device without a stat).

Utility meter does not convert power to energy. Integration sensor converts power to energy.

Yes!! That's it: https://www.home-assistant.io/docs/energy/individual-devices/#devices-with-power-w-sensors Thanks.
