Stairway lighting

Quick usermod to accomplish something similar to this video.

This usermod allows you to add a lightstrip alongside or on the steps of a staircase. When the userVar0 variable is set, the LEDs will gradually turn on in a Wipe effect. Both directions are supported by setting userVar0 to 1 and 2, respectively (HTTP API commands U0=1 and U0=2).

After the Wipe is complete, the light will either stay on (Solid effect) indefinitely or after userVar1 seconds have elapsed. If userVar0 is updated (e.g. by triggering a second sensor) the light will slowly fade off. This could be extended to also run a Wipe effect in reverse order to turn the LEDs back off.

This is just a basic version to accomplish this using HTTP API calls U0 and U1 and/or macros. It should be easy to adapt this code however to interface with motion sensors or other input devices.
