MQTT

The MQTT implementation uses the ESP Home's pattern for auto discovery. The topics for status and control of the light will be under {app}/light/{id}. Where {app} is the name of the yaml file without the extension, and {id} is the device_id inside the yaml file.

StateTopic: {app}/light/{id}/state

• Payload is json formatted: {"state":"ON","brightness":255}

Command Topic: {app}/light/{id}/command

• Same JSON formatting as the state topic
• state is required and is either ON or OFF
• brightness is optional with a range of 0-255

Brightness Command Topic: {app}/light/id/command/brightness_pct

• Changes the brightness without changing the state of the light
• Payload is an integer in the range of 1-100
