Cables and plumbing. We position most of the cables within the “chimney effect“.This way the electric current that powers the house and the cables for the sensors are safe and sheltered from the environment. It’s quite easy to reposition them in time if need be. It’s like putting the cables on the outside of the wall. They are easily accessible. The cables go in a vertical position all the time so it won’t interfere with water pipes or any other electricity cable. In case we want to change the position of the sensors or the sockets then we can do it easily. All we have to do is reposition the cables under the false facade.
This way we can add or subtract anything at any time in minutes and without destroying the walls. We don’t need to repaint the house. The only thing you will have to renew is the 1*2 or 5*5 cm gap where you extracted the power outlet. I know it’s not perfect, but it is so much better than destroying tens of meters of wall. This would mean emptying the room… dust, loud noises and workers for days. Nobody wants that. You might change all of the cables and wires within a few hours while your kids sleep in their room. Slightly exaggerated here to show you the point.
