Are you aware that laundry machines makes a beep sound when it completes its cycle, letting hearing people know it’s finished so they can go do laundry immediately. We cannot hear that, but we can use smart home things to help us. We can have lights flash for a number of things, but you can add laundry to that list! Use a vibration sensor and place it on the laundry machines to tell you when it is completed, then you can go get your laundry. The possibilities are endless!
What was used here to make it possible are Hubitat hub (SmartThings can also do this), Aeotec Multipurpose Sensor and LIFX light bulbs.
