The white walkers are preparing their army...you know it, It’s that time of the year when “winter is coming”. Wouldn’t it be nice if you could be one touch away from a nice, warm and cozy home temperature? Is there something as magic as an app that can rule them all? But what if you could do even more than that? Prepare your own summer at home, straight from your office desk. You no longer need to have a centralized thermostat that controls the temperature in all the areas. You can have different but uniform temperatures for every room in your home, with relative cheap components and the satisfaction of building the system yourself.
