Hi Steve,
many thanks for editing my translator and presets. Now it works exactly as I want to get 
I only had to change the reverse channels for APC MINI 1 and APC MINI 2, because when I press the button on APC MINI 1, the light goes on on APC MINI 2 
If you want to take a look on, I send you the actually project as attachment of this post.
Kind regards,
