Comparing Total Energy Use with HVAC use

Configuration
1

I have a sensor called sensor.total_energy_last_hour that tells me how much total energy I used in the last hour (I also have sensors for yesterday, last week, and last month) that pulls data from my smart meter. Since the HVAC uses the most amount of energy but I currently have no way to monitor the hourly energy use I want to compare runtime of the HVAC cooling, HVAC fan and HVAC heating with total energy use. (I’ll add other devices later.)

I created sensor.hvac_action so that I can tell when the HVAC is cooling, fan only, heating, or idle.

Due to a post here I am in the process of creating history stats sensors called Cooling On Today, etc.

Then a sensor Cooling On Today Minutes that converts it to minutes with {{ states('sensor.cooling_on_today') | float * 60 | round() }}

I plan on then creating a utility meter that tracks it at an hourly rate which will be called sensor.cooling_on_today_hourly

Then a sensor called that tracks the last hour called Cooling Last Hour with {{ state_attr('sensor.cooling_on_today_hourly','last_period') | round (2) }}

Is there an easier way to do all of this or does this have to be this complicated? If I do all of this with all of my devices that I can track on time for or kWh then I will have a ton of sensors.

This is what I have so far for cooling. I’m still not sure that I should use all of those calculations to get the runtime of the HVAC in cooling mode.
