Similarly, I have my desk lamp outfitted with Hue lights controlled via HomeKit, which always turn on 15 minutes before work and turn off at the usual time I clock out plus 15 minutes, and for the days I close up in time, I make it an absolute habit to turn them off before heading back upstairs to be with family.

It takes commitment to consistency, but it’s extremely effective for me to associate the light switch to my work day.
