@dazz maybe have a look at the PVOutput module which is intended to display data from your solar system ( if you upload data to PVOutput) if you don’t have a solar system uploading to PVOutput you could browse the available systems in your area and display their data. It would give you a graph of the current solar intensity through out the day.

Hi not sure if it’s been done but I can’t find it on Google, can someone use the Geo Home app to integrate into the smart mirror?
