Spontanious associations

Hello,

I do have a question about zwave (in HA via Zwave JS).
Every now and then a fibaro rgbw controller initiates a whole lot of associations by itself. Anyone some idea how that is possible, and - more important - how do I prevent this controller to do so?

Why?

Just guessing, but turn off discovery in Home Assistant.

That is unrelated to group associations.

Why?
Because the devices connected to the RGBW controller in this way start doing something at the most unexpected moments, every time the RGBW controller has a new value...
And the devices are connected complete randomly.
