Will the Hue go work with routines and timers when it is not connected to power? 

No, the Hue go will automatically go to “Off state” after 2 hours of being unplugged from the mains, which means it wont respond to commands sent from smart devices or timers anymore. To  be used as wake up light or for a routine, the Hue go needs to be plugged into the mains.
