I like how it can be used to connect with my home appliances using different methods such as WiFi or Bluetooth.
Also, i really love being able to control them remotely from anywhere in the world. Sometimes there are issues when connecting through internet because sometimes they don't have enough bandwidth available but this is something we should improve by adding more servers around the world so everyone will get better service. We use remote access software called OpemRmote Access which allows us to monitor our house's electricity consumption and also its temperature via an app installed on smartphones.
