Hi Dave,
I basically have two flows, one for feeding back measurements and the second for collecting forecasts.
I was about to create a new thread under the "share your projects" category here, as this thread is not intended to carry this information. I hopefully can manage to do that today.
Edit: see my example here: Power Forecasts and Data-Tuning for Solar Installations (Node-Red / solcast-API / InfluxDB / Grafana)
It takes about 10 days, after starting to feed measurements back to solcast until pv-tuning kicks in, but it definitely works well.
regards,
Fred
