Basic hue scene activation from aqara switch

Hello all,

Went around the forum but couldn’t quite get what I was after.

Here is my situation:

  • one hue bridge pro with one room and one scene within that room (added to ha-can see the room and the scene within the room)
  • All the light bulbs in the room are hue lights
  • one aqara h2 1 channel switch (added to ha through z2m- I can see the actions from the switch) connected to neutral wire.

Now for what I would like to achieve and am a bit lost as to how:

  • the lights in that room should never have the current cut off (I.e be unreachable)
  • When the user presses the top button
    ** if some lights are on (could be a scene or not), turn the lights off
    ** if the lights are off, activate a specific scene
  • when the user presses the bottom button, cycle through the existing scenes of that room (order should be kept so user knows e.g 3 clicks gets scene blabla and 4 clicks gets scene bloblo)

Additional questions: how can I make sure that the lights are never unreachable? I tried moving the switch to decoupled but I’m not sure what this does actually !

Thank you very much for any help you could provide. Code is fine as I will need to industrialize the production of all this setup for the numerous rooms and switches in my house.
