Code: Select all

return {

   on = { devices = { "Risque" }},
               
   execute = function(dz, item )
        if old.item.state == "RAS" and new.item.state == 'orage' then
            notification
		elseif old.item.state == "orage" and new.item.state == 'RAS' then
		    notification
        end
   end
}

You cannot get the previous state from the object API. You'll have to use some persistent data and store the information there.

Code: Select all

return {
   on = { devices = { "Risque" }},
   data = {
      previousRisque = { initial = "RAS" }
   },
   execute = function(dz, item)
      local state = item.state
      local previous = dz.data.previousRisque
      dz.data.previousRisque = state  -- don't forget to update the persistent data!
      if previous == "RAS" and state == 'orage' then
          notification()
      elseif previous == "orage" and state == 'RAS' then
	  notification()
      end    
   end
}
