In this episode of DIY or Buy we will be having a closer look at Smart Plugs, Sockets, Outlets.....However you want to call them. I love using such Smart of Wireless outlets to completely disconnect my appliances from the grid and thus getting rid of the standby power. But commercial smart outlets do often fail when I use them. So in this video we will investigate this problem, find a solution and possibly build the BEST DIY Smart Outlet that exists. Let's get started!
