Do I need a separate Hub or gateway for Smart Wall Socket?
It depends on the version you choose Wifi or Zigbee Version.
If you choose a WiFi version-connect directly to your home 2.4GHz WiFi network. No extra devices or costs needed.
If you choose a zigbee version-you need an extra zigbee hub to work with the wall socket.
