Tapo P300 powerstrip "on since" entities keep changing state when socket is steady on

[mvdwetering]

The problem

When I was looking through my Logbook I noticed there were a lot of entries for the "on since" entities on my recently added Tapo P300 powerstrip. All those entries makes it hard to find the stuff I was looking for.

Next to that the sockets have been On for days, so the "On since" state should not change.

Note that there are 2 "on since" entities in the screenshot, but both have been On for days.

Additional information

Looking at the history for today it seems the state is stable for a while and then gets unstable for a bit and then becomes stable again and keeps repeating

Attached is the csv from the view in the screenshot. It seems the "seconds" part of the timestamp is changing over time. history (1).csv
