Hi @SunsetRunner - Glad you found us here in the forum. Welcome. Here is a link to the Fitbit explanation for “How can Fitbit help me track my temperature.” It addresses topics such as What is Core Temperature, How does Fitbit calculate it, and How Do I see my Trends. Hopefully, this will give you the detail you want. For me, the biggest value is to see if my core temp rises. That can indicate a fever and illness. This can be a good tool in these covid days. If you have more questions, let us know.
