Missing Heating Temperature Slopes

My heating temperature slopes are missing. They disappeared about a month ago, just after I had some major insulation work completed. Is that due to a significant change in my home performance that requires new slopes to be generated using a new data set? I’m not using a custom date.

Beestat is such a great tool. I work in the energy industry and tend to obsess over my home’s energy efficiency data. I would love to be able to see the data on how much my home performance has improved.

Generally that shouldn’t happen, but technically it’s possible if the new data was significantly different as beestat would start seeing a lot of statistical outliers in the data and throwing things out. It should settle back in over time, but I’m happy to take a look if you send me your serial number.
