I have the problem that my PV production forecast sometimes doesn’t match the actual generated electricity at all.
I noticed that there is an additional parameter called “actual” in the estimate endpoint, but Home Assistant is currently not using it.
It would be possible to report the actual yield hourly to improve the forecast. That way, the premium access would also make sense, as right now, it doesn’t provide any real benefit in Home Assistant.
The adjustment should be relatively quick to implement—a simple checkbox to enable reporting of actual values and a field to store the entity ID of today’s generated energy.
