Hampton Bay ceiling fan/light - log readings

I have the Hapton Bay ceiling fan/light on HE. It is working fairly well (after adding a zigbee device closer) but see odd activity in the log. BTW - we hardly ever turn on the light.
Seems nearly every hour the ceiling fan light is turned off and set to 20%.
Any ideas ? I've got no rule/schedule for this device.
he log

I've seen this on Sonos devices as well. I suspect it is really just a "current" status message rather than a report of an action on the device, but I could be wrong. I would turn off "descriptive text logging" on both child and parent if possible (I'm at work and don't remember, sorry).
