EnOcean Alliance shows how to save 3 hours and 20 minutes… in a 3-hr, 20-minute film
Energy harvesting wireless technology allows various switches and sensors to work without wires or batteries. They can be installed in less than ten minutes, as opposed to traditional switches, which can take 3 hours and 20 minutes (since you have to open up walls, run wires, install the switch, fix the hole, repaint, etc).
What to do with the time saved? Or how to kill… 3 hours and 20 minutes in front of the camera? Enjoy watching.
