My 2015 iMac wakes up by itself with Sierra (logs inside)

[qap]

Hi,
Since the sierra update my iMac suddenly turns on the screen about every hour....after 1 minute the screen goes off again but the iMac stays on for another 15 minute (my normal sleep time) but I can't understand what is the cause of the wake up. From the logs seem to be the "hidd" process that detects a gesture on the trackpad but nobody is using it and the feature "Let Bluetooth devices to wake up this Mac" is disabled...

Any help is appreciated

Nobody knows what is the cause?

I solved the bug by simply check "allow the Bluetooth devices to wake up this computer". I don't know why but now my iMac doesn't wake up anymore.
