Alexa ReportState

Anyone know why this appearing in my logbook overnight at the same time for 34 of my alexa exposed entites and then 2 minutes later the other 24 ?
Thought it would only send it when an individual entity state changed ?

Checked my history and none of the entites changed state at that time (01:24)
