Is there a reason the standard Classic fan runs for a second or so late at night? Maybe 2100 or so. I have only noticed since I upgraded to the most recent firmware.
Unit is mounted on the other side of a bulkhead from our bed so the fan can disrupt sleep.
If the Classic is configured to reset at midnight the fans run for a few seconds after rebooting.
What Rest home said, It sounds like A-RST in tweaks is on causing the classic to reboot every night at midnite, You could disable that or intentionally set the clock off by say 3-4 hours so the reboot happens earlier, This will of course skew the logged data slightly but thats all
Yep... that was the issue. Thanks people.
