Only As Smart As What It Eats
One of the basics of any Smart Home that is often just assumed is that all of our switches and bulbs and voice activated toilet brushes run on electricity. To take it farther, most of them control electricity whether by turning a light on or off, activating an appliance or changing your home's temperature when a presence is detected. All of these things are either starting or stopping the flow of electrons through out your home. These electrons are the food that your house eats.
But Schmoid, I can hear you say, electrons are electrons. There aren't some that are better for your home than others, right? There aren't high protein electrons or gluten-free electrons. There's just electrons and they don't change on any level whether they were generated by burning coal or exposing photo-voltaic panels to sunlight. You are correct, I reply. But electrons aren't the only aspect here. There's also 'Smart'.
