Light Transition

[aavanzyl]

Hi, love the project, thank you for all the hard work.

I want to have the ability to specify the transition time for a Light entity. Do you have plans on adding this in the near future?
My usecase is basically for my aquarium, I try to simulate the sun going down so I slowly transition between the colors (basically an hour) to ensure a close environment for my planted tank.

If you have no plans on adding it, I am happy to assist and submit a PR.
