I am trying to write some code on how to decide when to charge my boiler. For this I would like to use solar forecast data from forecast.solar. However, it does not predict things that well.
O dear. That’s not good
To be honest, you should not look at a single day. Every now and then there is a day where the prediction is way off. It is not always clear where the edge of big clouds are going to be.
There are threads on the forum for alternative solar forecast Integrations…have a search for Solcast and/or OpenMeteo Solar and you’ll get the details…
Solcast…a lot to read in here (start from BJReplay repository posts since May 24)
There’s also a REST sensor config in this thread for Solcast data
