Kindling
A nightlight, or a ring that moves with the music. An Echo’s own ring will do neither.

On a real Echo
Amazon does not let a skill, routine, or app hold the built-in light ring as a nightlight, or paint it from music. The ring only reports status: blue while Alexa listens, red when the mic is muted, yellow for a notification, green on a call, purple for Do Not Disturb.
Keep Alexa. Echo Glow is Amazon’s color lamp, with mood lights and music modes. A warm smart bulb on a good-night routine is the other way that doesn’t open the speaker.
Replace the software. LibreEcho is an open-source system for the Echo 2nd generation, and experimentally the Echo Dot 2nd generation. It can run a sleep light and a music visualizer on the real ring. You lose Alexa, Amazon Music, and the cloud. Flashing uses the internal USB pads — a bad flash can brick it — and current Dots are not supported.
