In brief, I have a son who is on the autistic spectrum, and I need to control his access times to wifi as he struggles with any sort of self-discipline regarding when to stop. If I don't turn off his wifi he doesn't sleep and then doesn't get up. Routine and order work well for him.

At the moment I am using the wireless schedule to turn on and off the wifi at set times. However this now intterupts other wifi connected items in the house as it's a sledgehammer to crack a nut! Things will only get worse as more household items become connected.

I would like to be able to control access by time for just his devices only. how do I do this? I cannot see an easy way? What are my options.

Thanks in advance.
