Solar forecast as a Home Assistant entity

[SimBer170]

Is it possible to transfer the remaining solar production, which corresponds very well with the real conditions, as an entity to Home Assistant?

what's missing in attributes of sensor.evcc_forecast_solar ?!

[SimBer170]

Sorry, I overlooked the attributes. I've found them now. Thank you very much.

Could this sensor be used in home assistant energy section? Is there a sensor for the remaining production of the day?

Is it also possible to have the "adjusted values based on real production data" exposed in the attributes?

[marq24]

there is an optional single value called scale in the forecast:solar object (in the api/state response of the evcc server) - when toggle the switch in the evcc GUI all values will be adjusted by this factor - so if you must make the same operations in your HA template code...

... and I must double check, if scale value will be also added to the attributes...

[update], IF scale is part of the forecast:solar object/dict, then it will be also present in the attributes of the Sensor

[alex-voigt]

That is awesome. Thanks for the fast response!

Could you help getting remaining production with scale in template sensor?

you can use https://duckduckgo.com/?q=ai&t=chromentp&ia=chat for this kind of requests

Is it possible to use the evcc forecast for the energy overview, similar to the forecast.solar or the solcast integration and if so: how would I configure that? I would realy like to have an overview from a single source of truce. Here is an image to clarify what dashboard I mean:

technically it should be possible to create a template sensor, that will generate from the new format (which was introduced with the release of 2025.12.2 today) a content that is used (can be consumed) by the Energy Dashboard - but I must admit I don't have a single clue what must be the target format...
