Code files for my projects involving an ESP8266 and NodeMCU that need a working wifi connection.

• Split in multiple files
  • config: Global variables for all nodes, updateable via MQTT?
  • init: Connect to wifi and then call lamp code
  • multiple modules for different projects, see below for a description

Modules

Each module file implements a function to indicate when the next step of the startup is reached and a function to start.

• lamp: Control the color of WS2812 LEDs (like in a NeoPixel Ring) via MQTT.

Feature ideas

• Updates over-the-air
  • Either over MQTT (nice for many nodes) or HTTP
  • Checksum / Signature: No asymmteric crypto available, maximum is HMAC
  • At least updatable config
• Configurable via web interface
