I use Hue bulbs and an Hue LED strip at the moment via zigbee ZHA and tie them to the circadian integration to auto adjust the brightness and temperature settings through the day and night when they are on via motion sensors and manual toggle
I have recently setup hassalarm on my phone to tie the alarm times automatically to my HA instance and used a boolean input to toggle it to have the lights I have in the bedside lamps act as a light based alarm.
