This variant additionally replaces the manual, rope-operated mechanism to open and close the lamp with a remote-controlled motor.

The firmware is based on ESPHome, and its excellent Home Assistant integration enables one to implement higher-level features, like a "sundial" where the aperture of the Deathstar follows the sun elevation throughout the day (see the timelapse video).

That said, I will not consider this project as complete until the Imperial March can be played over the stepper motor (just like the legendary Floppotron) ;-)
