Direct access to statistical/historical data

[arganto]

If I want to have an own dashboard with the e.g. energy consumption of several sensors for today or this month, I have to create utility_meter sensors. Same for graphs, etc, e.g.distribution today.

So from a sensor

sensor.foobar_energy_counter

with

state_class: total_increasing
unit_of_measurement: Wh
device_class: energy

I have already four sensors for daily, weekly, monthly and yearly.

energy_counter_foobar_aktor_daily:
  source: sensor.foobar_energy_counter
  cycle: daily
etc.

But HA can select and display it without such utility_meter sensors.

As this integrations is already number one in loading time and I have already >150 of them (growing) and can only have fix time-ranges with this, I wonder, if it would not be more than beneficial to have direct access to such data, e.g. in a kind of virtual entities, like.

sensor.foobar_energy_counter:daily
sensor.foobar_energy_counter:weeky
sensor.foobar_energy_counter:monthly
sensor.foobar_energy_counter:yearly
sensor.foobar_energy_counter:timeframe[01.06.2022-10.06.2022]

So I can directly use them as entities in dashboards, graphs, etc.And reducing the overhead of the utility_sensors directly with that.

Using values of energy management in dashboards

I love the new energy management feature as it is very similar to what I am already using (though significantly easier). As I use some features in existing dashboards I was wondering how I could use the values in existing dashboards without the need to use the energy cards themselves. Would it be possible to extract those values from the database or something? See below an example which basically shows the energy consumption since midnight. [Screenshot_20210912-075321]
