Connect OpenHab 1.x to more than one avm fritzbox

I’m operating three fritzboxes from AVM in my house. I would like to turn of the WIFI on all fritzboxes, when leaving the house.

But if I get the configuration of the fritzbox binding right, it can only connect to one single fritzbox which makes it impossible for me to turn off wifi on all the boxes when I’m leaving.

Am I missing something in the documentation or would the binding have to be changed to support multiple fritzboxes?

No, only one box, see issue/feature request here:
