I suggest Kasa Smart Plugs. No hub required, use a phone app. You set a cadence of on and off times and control manually. App control provides a kill switch capability. Very inexpensive, $20 to $30 for 4 plugs. Obviously, your children could remove the smart plug and just plug the tv into an outlet.
