I’ve been experimenting with the Sleep Schedule on my Starlink Mini today and seem to have found a consistent one-hour offset while we’re on British Summer Time (BST, UTC+1).

As a test, at around 13:20 BST I set the sleep schedule to 14:30-16:30.

At 13:26, the Starlink app correctly displayed the schedule as 14:30-16:30, but said that Starlink was “configured to sleep starting in 4m”.

Sure enough, at exactly 13:30 BST, the Starlink went to sleep - one hour earlier than the displayed 14:30 start time.

The one-hour difference corresponds exactly to the current BST/UTC offset, so it looks as though there may be a timezone/DST issue somewhere in the sleep scheduling.

I’m aware that Starlink’s own documentation says that “The Starlink App uses UTC (Universal Time) by default.” However, that doesn’t explain this behaviour - in fact, the observed offset is in the opposite direction. If the displayed 14:30 schedule were simply being interpreted as 14:30 UTC, that would correspond to 15:30 BST. Instead, the Starlink sleeps at 13:30 BST.

I’ve done similar tests before and seen the same behaviour.

Has anyone else in the UK, or another timezone currently observing daylight saving time, noticed this?

The Mini is always on the latest firmware and the iOS app is always up to date.

Starlink Mini Sleep Schedule appears to be one hour early during BST
