Setup

  1. Ensure HA has a user for ESPwifi to use
  2. Access ESPwifi module
  3. Turn on MQTT
  4. Publish to homeassistant.home.arpa, set username and password
  5. Base topic is emon/espmon OR homeassistant/sensor/espmon

The published data is just sensor name (CT1 etcetera) and the value. Home Assistant appears to want more complex data structures.
