Energy Calculation

[Korol-Yurii]

Perhaps it is possible to "catch" the idle state of the water heater by the help of small calculations between current water temperature and set water temperature. In case current_temperature<set_temperature the water heater is working. The power consumption is also known because it can be of 3 states. I usually use my water heater only at 2000W. So in configuration.yaml I've created a simple binary sensor to measure power consumption.

`binary_sensor:

• platform: template sensors: boiler_state: friendly_name: Boiler State entity_id:
  • binary_sensor.boiler_state value_template: >- {%- if (state_attr('climate.water_heater', 'temperature')-state_attr('climate.water_heater', 'current_temperature'))>1 -%} on {%- else -%} off {%- endif -%}

sensor:

• platform: powercalc entity_id: binary_sensor.boiler_state create_energy_sensor: true mode: fixed fixed: power: 2000 name: "Water heater consumption"`

I'm still testing this scenario. Any thoughts about its usability?

I already thought about a similar implementation, but I didn't get around to checking everything ) So if your test was good enough I will implement this feature.
