[Feature Request] Real Power Sensor Device Association

[bramstroker]

@DellanX I have added some feature #2056, however this only applies to the energy sensor generated by powercalc.
So with this feature you are able to attach the energy sensor to another device (in your case Roku TV)

On hindsight I'm reading your question again, but I think you were talking specifically about the power sensor (W), not the energy sensor (kWh).

The "Real power" option for powercalc is exactly the same as the "Riemann integral sum" helper which HA core provides, but with a few additional options.
The purpose is to create an energy sensor for an existing power sensor.

Your feature requests seems about replacing the existing power sensor with some proxy entity provided by powercalc.
But this is not something I'm going to add in powercalc, as it is out of scope for the integration. Don't want to "pollute" it with this kind of exotic feature, which almost nobody would use, and also difficult to understand for most users.

Your question essentially boils down to be able to attach a given entity to multiple devices, but I think this will never be possible in HA, as this requires massive architectural changes.

When you want some kind of proxy sensor you could just do with a template sensor in HA, and make a feature request for the ability to add a template sensor to a specific device. I think this feature was requested multiple times before on community forum, so you could also cast your vote there.
