Xiaomi Home loosing Yeelights every morning

Hey all, I have two Yeelights connected via Xiaomi Home. Since a while every morning at 4:45 HA loses connection to the lights. I know it’s not a Xiaomi issue as I also have a vacuum robor which has no issues. Also, I don’t think the lights are to blame as they are fine in the Xiaomi Home app.

I have no automation running at that time, they simply become disconnected.

Any idea?

Isn’t that around the time system backup and housekeeping occurs?
