Turning ON/OFF Two devices at once (garage doors + outside lights)

Talked to my father about our newest purchase. Outdoors lamp, that you can switch on with eWelink app. My question would be: is it possible to switch two devices on/off at the same time with one button instead of two seperate buttons?

There are 2 options:

  • You combine the devices together in a group (Device Setting → Create Group)
  • You create scenes that sync the status of the devices: (1) If device 1 on, then turn on device 2; (2) same for off
