expose per-room and per-floor power aggregates

[jharmsen845]

Describe your idea

The Home Assistant energy dashboard computes aggregates over floor and room when showing energy flows over time and also current power flows. These aggregates are useful outside of this Energy page, and it would be helpful if they were exposed as their own entities. For example, I have a per-floor dashboard where I can drill down from First Floor -> Kitchen or Living Room. From there, there are multiple sensors in each room which I don't necessarily care about in individuality but would be interested in understanding in-sum.

I could use template sensors to add multiple sensor values together, or try to do this by room or floor more dynaically, but this does not scale well, nor will it handle dynamic environments where I add or remove power sensors to certain locations.

It would be helpful if Home Assistant exposed the energy aggregates that it is already calculating as their own entities.

Why is this exciting?

This prevents a user from creating many, many template sensors to achieve this.

Potential use cases

• See floor energy consumption at a glance, and then drill down in your dashboard to rooms, then to devices, etc.

Anything else?

One obvious problem here is how you will dynamically name these entities... I do not have a solution to that.

Interesting suggestion, but I see an issue with regards to devices that are double in HA:

• RGB Zigbee lights, in a circuit that also has a WIFI/Zigbee/Zwave/? switch behind the physical switch: in that case, you will have a double count (EM from rgb lights + EM from switch). Of course, you coulbd manually disable the PM & EM of the zigbee RGB lights, and only have the PM & EM of the switch
• devices that integrate in HA through both native integration as well as MQTT. I have that issue, as I'm using the MQTT interface as well for an additional testing environment. And as this uses the same MQTT broker, also my production environment is picking up these devices. This also would lead to double counts

To achieve the result you are after, I personally have created Group helpers for power and energy measurement (not per floor, but per device type). Works fine, but only manually scalable...
