Vera 3 as secondary controller from Fibaro HC2


Before I tried to add Vera 3 (UI 7) as a secondary controller of my HC2. That was working, but I stopped with the integration. Now I want to start the integration again. Several months ago I could change the zwave version in the Vera to 2.78, but that is not possible anymore? Anybody experience how I can add now the vera 3 as secondary controller?
