In the Find My App - why does Macbook show a random time in the middle of the night?

I have family sharing on, and one of my own laptops was showing a timestamp of 3am, but I was asleep then. Will a macbook ever periodically "ping" its location, or is it exclusively when it is being requested? I asked all my family members if anyone was awake then and looking at the app, but everyone said they were asleep. Is there another reason that a macbook may show a time when it's not actively in use, or if its location is not being requested?
