GE Cync Undercabinet light turning on in the middle of the night

I have two of the new GE Cync undercabinet lights. They are connected via matter over wifi, using the Matter Server add-on. One of them is turning on randomly.

Looking in the logs, I see a message like this every time it turns on:

The only responses I see that include AttributeReportIBs correspond to when the light is turning itself on. Generally, the response from this device and the other one, look like this:

Is this an issue with the device, or with the matter server? Any ideas on how to stop the light turning on in the middle of the night?

Thank you,
Grady
