Hello dear Community,
I have configured an apexcharts-card to monitor the power generation of my PV System.
One problem I noticed, due to some reasons that I ignore, the prevision from solcast fails sometimes to update data correctly. In occurrence, the service updates all the entities of Solcast but fills them with zeros.
What I want to do :
Create a sensor with all attributes of the entity sensor.solcast_pv_forecast_prognose_heute
and update this sensor only if the state value is non zero (state of the sensor is the solar energy prevision, thus should be strictly bigger than 0 kWh).
The new sensor should then always be filled with non zero attributes, and I can generate data and sketch them in the apexcharts-card even if the Solcast update fails to get correct data.
“normal attributes” looks like this :
unit_of_measurement: kWh
device_class: energy
icon: mdi:solar-power
friendly_name: Solcast PV Forecast Prognose heute

However when the Solcast update is faulty, all values of attributes are equal to zero.
Thank you a lot for helping
