Smart plugs were $7 apiece. I can afford it. Not sure how controlling my lights is controlling myself. but I enjoy going to bed and simply saying turn off all lights and poof, lights are off.
Also enjoy all the other benefits of light control, music access, most radio stations across the country (Iheart radio), weather forecast anywhere in the country and encyclopedia all within sound of my voice. Other benefits like set an alarm for 4 minutes (eggs) or set reminder every Monday at 7pm to take out rubbish. All sorts of life controlling things, all well worth the small expense.
