Integration with Span?

Does Panel provide the current frequency for each leg? I regularly go off grid in the morning hours and noticed my LEDs flickering. Now I’m certain it is frequency shifting of the Tesla Gateway but would like to know so I can log it somewhere and be able to see what the frequency is.

I found a way to view it from the Tesla API, but would love it to come from Span if it is a sensor already we just don’t see right now.
