Hey all...I have too many kids to count, and they all have numerous devices (personal laptop, school laptop, maybe a tablet or game station)...

What tools are you using to shut down their devices and keep them off at night?

I really dont want to manage each individual device, so I was looking for something that might be connected to the router...

Edit1: its all android devices

Edit2: i really cant impose rules on some devices (school laptops) and would have to manage this on all devices (at least 15 devices across 5 kids)

Edit3: I definately want to shut the devices off at different kids at different times 5 year old earlier than 14 year old) and have different web site accessability (5 year old gets youtube kids, 12 year old gets youtube)
