An integration with SolCast’s API compatible with the Energy Panel would allow Australian and New Zealand HA users to configure the full extent of the Energy Panel.
The problem is that the only current solar forecasting integration is Forecast.Solar, which only covers part of the globe.
The solution is to implement SolCast. which has:
Rest API with comprehensive documentation
30 minute update intervals
Free account for 50 API calls per day
Covers all areas including Australia and New Zealand
