Tutorial: Compare Your Solar Forecasts! (Easy Home Assistant Blueprint)

Remember my solar forecast comparison video a few weeks ago? (https://youtu.be/SAwSA6C4-Qw) Well @GaryDoesSolar asked me if it was possible to make comparing solar forecasts easier for anyone who wanted to do so. I had a good think and came up with a Blueprint for Home Assistant and in this video I’ll go over everything you need to know and do in order to configure it yourself. There’s an article to go along with this video: https://www.speaktothegeek.co.uk/2025/08/tutorial-compare-your-solar-forecasts/
