There is an article on auto-calibration of TRVs here [Your TRV is lying to you: TRV auto-calibration - NotEnoughTech](https://notenoughtech.com/home-automation/trv-auto-calibration/)

While the TRVs and sensors used are zigbee the concept and ideas are still relevant and could be re-done for the Shellys with no bother.

I started looking at this because the TRVs used are the same as I use and there is a whole series of related articles.
