Plus one here for Solcast. Solcast’s API allows 50 calls per day (upgraded since closing their tuning system). And their documentation is much more professional than Forecast.solar
This is the first time Home Assistant has released a core feature that does not cover the whole world, focussing on Europe and North America. I’m not sure that this follows the charter for Home Assistant (if one exists). Personally, I find this extremely disappointing after using Home Assitant for years.
Australia has the highest number of rooftop solar installation per capita in the world and is also one of the highest HA user bases (probably highest per capita again).
Leaving out a valuable user base is a poor decision.
Integrating Solcast would be relatively simple for a competant programmer (I.e. Not me!) as it is a REST API.
Home Assistant - please fix the Energy panel to allow the whole planet to benefit from this integration.
