Hi NZXT Team :)
I believe this to be the best place for feedback; posting this on the behalf of many redditors that I found would like the same feature, as well as myself:
Could we have a 'sleep mode' feature considered for the lighting module within the NZXT Cam app? This may be enabled/disabled as well as set for specific time period, and/or on an 'inactive/AFK' parameter, such as traditional screensavers use after x-amount of time of inactivity. In any case, just a way to automatically turn off all lighting provided through CAM controller.
Cheers!
Jules
