Simple multipurpose light to show different statuses on an array of LEDs. Exemplary use case: placed between two office doors, each half of the ring showing if the person within the office is free to talk or occupied.
3D printed case by marcluer is available on Thingiverse.
Any ESP board with WiFi and a WS2812 LED strip, matrix or ring should work.
This specific config was tested with:
- Wemos D1 Mini
- Neopixel ring (24 LEDs)
- PlatformIO CLI
Define hardware settings in main.h, set up the number of LEDs and segments there.

You can either control the status light via segment numbers or add names to segments in persistent memory.
