3 different methods to use scenes with Google Home & openHAB

It’s basically the same code as activating a scene but easier. It’s triggered by the same Item but OFF-command instead of ON. The for loop goes through all items controlled by the scene, stores the storeItem name, then sends the i.state to the storeItem.

Hope that is understandable. You can probably write it cleaner than this, I’m a programming noob just copying, cutting and pasting different stuff that I find.

The only problem is that I would like to have the Scene activating item exposed to Google Home enabling activating scenes by voice. But if I for example say ,“Hey google, turn everything off.”, the scene switches would also turn off and erase all previous values stored. But that’s an other issue. For now i just never say, “Turn everything off”.

rule "Lighting Scene Store Generic"
when

    Member of LightingScenes received command OFF //Use this line if you're on OpenHAB 2.3 or later

then
    // Get the Group of Items that are controlled during this scene
    val items = Scene_Items.members.findFirst[ grp | grp.name == triggeringItem.name+"_Items" ] as GroupItem

    // Loop through all the Items controlled by this scene
    items.members.forEach[ GenericItem i |

        // Store scene Item name  
        val storeItem = triggeringItem.name+"_"+i.name

        // sendCommand the Scene state
        if(i.state !== null)
        {storeItem.sendCommand(i.state.toString)}
    ]
end

Merry Christmas!
