Way I make sure I dont spend too much time on it is......
Look at it when get home then leave it to play AH and dinner.
Look at it and fleetsave my main fleet it for a long time about 1 hour or 1 hour and half after I get home.
Build ships or whatever else I want to do before go on AH etc.
Start researches or whatever if didnt before going on AH or tv do it before bed.
Probe up the area before bed and send my fleets out for fleetsaving and getting res.
On weekends check it in the morning, midday, and night.
I never spend more than a hour on it the whole day.
