I currently use two types of Coway products, number of air purifiers and a water purifier. Neither of them particularly need to have IoT features, but recently Coway decided to sprinkle the smarts onto their new products. It does have its advantages. For instance, Coway water purifiers with built-in ice makers traditionally had light sensor to only make ice during day time. With IoT, Coway’s IoCare app can actually trigger when the ice maker function will kick in. There are still buttons on the appliances, so the app is technically secondary.
