Wasnt sure if to tag this on the end of someone elses query, however, can anyone enlighten me on the solar prediction on the plan? It looks wrong, which obviously would then screw everything else up:

Ive clearly done something wrong, it feels like my solcast api is giving the wrong data, and I dont know why that would be the case

This is from the solcast site

And this is from the Solcast PV Forecast

so you live closer to the sun than the rest of us 🙂 or your forecast data is off by 3 decimals to the right. In solcast did you enter your array or inverter size in Watts maybe as opposed to kw?

I'm no expert but I'd check your API key is correct in the Solcast integration. You seem to be viewing a Nuke?

paddyb Id assume that because it looks ok on the solcast site (2nd post) that its ok - but honestly Im baffled

Ok, I think having looked at my solcast account the page had several other arrays one seemed to be a solar farm in Belgium. I've deleted these, I'll see if that refreshes for me and corrects it all 🙂

If you look at the solcast_forecast_now or somesuch in Home Assistant you can see the hourly forecast that predbat will be using in the plan.

I thought I had a lot of panels with 44 on my roof, but it never gets to those kind of generation figures !!
