I want to leave electronics plugged in the outlets without worrying about they're using unnecessary electricity.

Idea:
Place an electricity controller in-between the breakers and the rest of the wires going to the outlets.
This controller will serve as a relay switch that let current pass in certain conditions (e.g. time of the day, demand, etc).
I don't need the switching mechanism to be per outlet. Usually, breakers distribution are well made and a relay for every breaker will do just fine for my needs. During the day all house outlets should be off minus the one affecting the fridge. Rest of them I want them to be turned on, initially, by demand.

What's out there?
Home Automation outlets
Smart outlets
