How do you do that?
Install the HA Companion app on your phone (I use the "minimal" one.from FDroid), and enable the Alarm Sensor - that provides the next alarm time (so, be careful if you have different alarms throughout the day!)
Then, I use that time to trigger the lights to start ramping up about 30mins beforehand.
Also... be careful to check if you're at home... took me a while to realise the lights were coming on whilst we were away.
Oh, and I use Simple Alarm Clock - also from FDroid - because it fades in the alarm sound.
