Short story: Associations works only if both devices are secure or both unsecure.

Solution: include the devices unsecure:

> [@Add Z-Wave device non-secure?](https://community.homey.app/t/add-z-wave-device-non-secure/12406/35):
>
> No cli installation necessary!! It works out of the box! grinning You only have to figure out which device forced already a unsecure inclusion. Thanks @TedTolboom Like the Fibaro Walli switch. By selecting the Walli switch you can include every device unsecure (as long the device support unsecure) grinning
