Breathe

Breathe is a small desk notifier. When something needs you, the top flap hinges open, pushed up by a servo, and a frosted band of LEDs lights up. Colours and patterns are whatever you set in your own firmware (for example Home Assistant / ESPHome): white, rainbow, warm reds, blues, greens, and so on. It plays short beeps and chimes, then closes itself.

What opens it, and what the lights do, is all up to the firmware you put on it.
