Fibaro Dimmer 2 Transition

I have a light connected to a Fibaro FGD-212. It doesn’t seem to work with a transition argument, is that correct? What would be a way to very slowly turn in the light as a wake-up light?

Thanks!

Here is a similar logic that you might be able to base it off of: https://github.com/dale3h/homeassistant-config/blob/fd5c2fe4737b5a29290fb21c3e4b4af337fc4a94/examples/slow_dim_lights.yaml
