That’s unfortunate to hear. I’m not a programmer, so I use Homey instead of Home Assistant. Perhaps there are other developers who can help you? Could you please post your question on the developers’ forum? ---

I am also not a programmer 😄 But I checked with Chatgpt and there are some options, so I will quickly try something after the holidays ---

I would really appreciate it if the requested function comes into the app. I am now working with the expected clouds. But that’s not reliable enough. Ask more experienced developers on this forum. No doubt someone can help you. ---

@Pieterv123 What’s easier for you? Adding the forecast for the next 4, 5, and 6 hours. Or the forecast for a specific time period? (I prefer that.) ---

Ah, there’s the camera. Still no image (black). I understand something will come up naturally. \*edit There it is. Looks good. I still get the camera logo as the background. Is there anything you can do about that? The graph is only displayed on the dashboard. It remains black in the device window. The graphics aren’t quite working properly yet. But that’s the time zone you mentioned earlier. ---

I added a background colour, maybe I could add colour options in the settings, but that is prone to errors. Also the optimistic and pessimistic scenario’s are added. Maybe in a few weeks I will make further updates ---

It uses the data from the last update from Solcast, So it depends on your interval. I could change it to current hour, but I think this option gives you a better view on quality of the data. ---

I have another fun challenge for you. Can you make the graph visible via a dashboard app widget? That will look even better. 😇 ---

Thanks, that saves me some calculations in my flow. And increases accuracy. I’ll test it. > [@Uitgesteld & geforceerd laden Homewizzard batterij](https://community.homey.app/t/uitgesteld-geforceerd-laden-homewizzard-batterij/139216/8): > > @Pieterv123 Heeft een mooie functie toegevoegd aan zijn app. Nu is het beter te bepalen of er voldoende zon verwacht wordt in de middag om in de ochtend de batterij stand-by te kunnen zetten. Het is nog in beta, maar om te testen de flow aangepast. Scheelt weer wat berekeningen. ---

I think there’s a bug. I set the time to 12:00 - 18:00. Threshold 9.004 (calculated). Remaining energy at 9:41 is 8.03 kWh. So the condition can’t be true. Yet, the value true is returned. Only when I set the threshold to 13 or higher does it return false. ---
