Utility meter, split in heat and cold energy usage with seasons

1

My (none smart) airco is connected to a power plug to measure the consumption of energy.
It only has one energy sensor:

sensor.smart_plug_aircos_maxicool_electric_consumption_kwh

If I make 2 extra sensors, for example:

sensor.smart_plug_aircos_maxicool_heating_electric_consumption_kwh
sensor.smart_plug_aircos_maxicool_cooling_electric_consumption_kwh

Is it possible to make it that the heating sensor only counts when the season is spring or summer, or specific months?

Easiest is to use the tariff function of the utility meter. You can set values for tariff types, and utility meter then splits it in separate counters per tariff. In your case, tariffs would be heating and cooling. The. create an automation to set which tariff is active at a certain moment.

Thanks! I did not know about the tariff function.
But if I understand it correct than this does not create 2 separate sensors?
I would like to show them in my lovelace and create a yearly and last_year sensor of both heating and cooling. Or can I choose what tariff from the sensor is shown in the lovelace and show both tariffs with one sensor?

It does create extra sensors, one for each tariff.

Thanks,

I made it like this:
