iMac keeps waking up about every 2 hours

Hello together,

since upgrading from Mavericks to Yosemite my iMac (2011) wakes from sleep about every 2 hours. This is particularly annoying since the iMac is located in my sleeping room. 😟

What I did do:

I unchecked the Energy Saving option for wakeup in case of network access, so network access should(!) not wake the iMac

I reset NVRAM

I reset SMC

I repaired file access permissions

Anyway, the iMac drives me crazy by refusing to keep sleeping. Is there any help out there for me? Had the same problem when I upgraded to Mavericks, btw.. The fix came in form of a OS-patch from Apple. *SIGH*

iMac (27-inch Mid 2011), OS X Yosemite (10.10)

I Just updated my iMac last night to Yosemite and this is now happening. It didn't do it with Mavericks. My iMac is next to my bed too, so I guess I'll be turning it off every night rather than just letting it sleep so my Backblaze backup could run. So annoying.
