Well, not afraid to admit I was wrong! I did not realize that. I just verified with one of the engineers and here’s the summary:
We pull the name from TP-Link initially. If you rename it in Sense, we do not push it back to the Kasa app. Once you override it in Sense, it will remain overridden, even if you change the name again in the Kasa app.
We’re certainly open to feedback on this. There are some technical limitations with pushing the name change to the Kasa app, but maybe it’d be better to not allow renaming in the Sense app? If you only rename in Kasa, your names should never go out of sync.
I’ll mention the data export request to the team.
