My concern regards lights. Is there a way, in a script, to poll every lights current status and save that state if the group address for the firearm goes true? 

The scenario would be this:

Fire alarm goes off. Every appliance turns off and all lights go to 100%. 3 minutes after the fire alarm has been reset, the lights go back to the state they were in before the fire alarm went off.

I´m not even sure if this is what people do when it comes to KNX and fire alarms...

what we do:
- connect all devices to a scene
- when firealarm on: save scene - turn lights on / blinds up
- when firealarm off: call scene

Thanks for the tip! Haven't worked too much with scenes yet. What you are saying is that you can save scenes on the fly with KNX, and not have to pre-program these in ETS?

Code:

value = event.getvalue()

-- save states
if value then
  objects = grp.tag('my_object_tag')
  store = {}

  for _, object in ipairs(objects) do
    store[ object.address ] = object.data
  end

  storage.set('my_objects', store)
-- restore states
else
  store = storage.get('my_objects', {})

  for addr, value in pairs(store) do
    grp.write(addr, value)
  end
end

Then create a 1-bit object an map event script to it. When writing ON (true) it will save current object values that are assigned to this scene. When writing OFF (false) it will run the scene.

Code:

value = event.getvalue()
name = 'Test scene'

if value then
  scene.savelive(name)
else
  scene.run(name)
end
