Sure, it's easy to find connected home appliances, but what if you want to add a dash of intelligence to many of your existing appliances (not just one or two)? LG might come to your rescue before long. It's launching a SmartThinQ Sensor which uses feedback like temperature and vibration to tell you what your devices are doing. It can tell when your washer has finished by waiting for the shaking to stop, for instance, or tell you if someone left the fridge door open while you were out. In some cases, you can even remotely control those older machines. There's no word on when the sensor arrives, but it'll be joined by the smartphone-controlled Smart Lightwave Oven and Smart Air Conditioner at the upcoming IFA trade show.
