Hey david, I start predicting my hot water temperature using the KNN. I run the fit endpoint everyday and the tune endpoint every week. I currently use 30 days of data and I noticed that the R² could really help to decide when the tune endpoint should be executed (e.g. an unexpected change in my hot water consumption or outdoor temperature). Therefore, I thought of using R² as an indicator in order to set the frequency at which the tune occurs. Is there anyway we can get the metric as an output?
Also, I made this visualization using Plotly integration for HA showing the future data. For those interested you can find the code here
