Motion Sensor Active after Firmware Check

For the second time in the last 30 days I’ve observed my lights turning on in the middle of the night due to ST motion sensor activity. The only correlation I’ve found so far is that this happens around the same time the device checks for the latest available firmware.

Has anyone else experienced this issue?
Looking at events I see:
