I have been browsing and configuring but am admitting that I need help as I have seen some very good answers for various other topics here.
I created a sensor as sum of two sensors
solar_energy_total:
friendly_name: "solar_energy_total"
unique_id: solar_energy_total
value_template: "{{ '{:.1f}Wh'.format((states('sensor.reverse_energy_a')|float(0) + states('sensor.reverse_energy_a_2')|float(0) )) }}"
device_class: energy
unit_of_measurement: kWh
and use this for three utility meters
solar_energy_daily:
source: sensor.solar_energy_total
name: solar energy daily
unique_id: solar_energy_meter_daily
cycle: daily
solar_energy_weekly:
source: sensor.solar_energy_total
name: solar energy weekly
unique_id: solar_energy_meter_weekly
cycle: weekly
solar_energy_monthly:
source: sensor.solar_energy_total
name: solar energy monthly
unique_id: solar_energy_meter_monthly
cycle: monthly
but only the monthly meter is in state Unknown with no history.
Is it simply because this monthly meter was not reset yet?
Do I have to wait for the next month or can I perform a manual reset to see it counting?
