Purpose

Monitor MQTT feed and activate status-light when appropriate

Target Configuration

• See config.h for parameter configuration
• WiFi SSID and password are contained in a secrets.h file that is not included in this repo. Instead you'll find the file secrets_template.h, which should be copied to secrets.h and then edited to supply the right access credentials and configuration values to match your deployment environment.
• common wire from light to COM on relay
• hot wire from light to NO on relay
• connect both 2 wire JST connectors

Status messages

• During initialization, setup()), will:
  • blink on and off 3 times for 1 second to indicate that WiFi connected and the light works as well.
  • blink on and off 3 times for 3 seconds to indicate a failure to connect to WiFi. The device will then reset and try again.
• During regular operation, if the device can not connect to MQTT it will:
  • blink on and off 3 times for 2 second. If the problem persists, this will occur again and again.
