> I have a few problems with hubs; you need to store the physical thing somewhere, and as a house with difficulties in getting a wifi connection to corners The hub only speaks WiFi to the app. All the smart units (hub included) use Zigbee mesh-networking for cross device-communication, which is self-extending and only gets more reliable the more units you add. At no point in time does IKEA or Hue bulbs depend on WiFi to function.
