Get Variables from furnaces?

[Livedeath]

Hey.
Can we get 3 variables, current amount of input ressource, type of input ressource and amount of output ressource from furnaces?
That would be building making logics with easier.
Like variable I is for amount of input ressources, O for amount of output ressources and variable R the specific ressource type (iron ore, iron plates, copper ore, stone).

Best Regards,

There are several suggestions about adding more variables from entities.
I recommend https://mods.factorio.com/mod/Inventory%20Sensor

Don’t list them all most can be found if you search for inventory sensor”.
