Good day,
Welcome to TP-Link community!
It is more related to the Daylight saving time that there would be one-hour time difference to the actual time.
We have got several feedbacks recently that the Kasa product cannot automatically switch to winter time.
And they will automatically enter winter time after November 1.
So you could have a check later and please feel free to post here with further updated news.
Thanks a lot.
Update: there would be another temporary solution:
Set the time zone of the Kasa APP to a place that does not use daylight saving time, such as Africa Algeria. Let the customer check whether it can be used normally temporarily.
