Home Automation/OpenEnergy Monitor
From Cricalix.Net
Setup
- Ensure HA has a user for ESPwifi to use
- Access ESPwifi module
- Turn on MQTT
- Publish to homeassistant.home.arpa, set username and password
- 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.
