Needs a Timer Function

It’s is decent at changing colors and brightness, but the Bluetooth is wonky. With some patience I got it to work.
This app badly needs a timer function. I use an Eve switch to turn the lights on and off though Apple Home, and the app remembers the last scene. I really want functionality to change scenes automatically. This is primarily (only) because I want to switch scenes at midnight, for example, from full lighting to just my flag pole. This can be as simple as “when lights go on, start with scene 1 and after five hours switch to scene 2”. Modern apps should have more functionality than just a timer in my example and should be clock based.
An upgrade is needed!
