<< Solved >> Wake up when turning on/off lights in room - message in syslog

[silvercircle]

Something funny is happening, when I put my hacintosh to sleep and turn on or of the light in the room the computer wakes up.
In syslog I see this:
Radio[539]: [RADIO] receiveWakeNotification: NSWorkspaceDidWakeNotification
But I'm not sure this is relevant because the same message appears when I wake the computer with a keypress on the keyboard.

I use a Logitech Craft keyboard and MxMaster 2s, but when I connect these directly via Bluetooth and remove the dongle the same is happening.

Wake on network activity is turned off, bluetooth setting to allow wake up from bluetooth devices is also off.

Any ideas why this is happening?
