Aurora inverter communication server written in Go.

This server fetches live data from PowerOne/Aurora PVI series (and compatible) inverters using the Aurora protocol and exposes them over HTTP in plain text, JSON and XML.

Based on Daniele De Santis' PHP InverterPowerMeterLITE project: http://www.desantix.it/index.php?page=show_articles&cmd=show_article&id=233

• Go 1.22+
• Network reachability to the inverter TCP interface (default 1470)

Using Go modules:

go build -o aurora-go

Or run directly:

go run . -r 192.168.0.190 -p 1470 -s 8100

Run with defaults:

./aurora-go

Flags:

• -r Inverter IP (default: 192.168.0.190)
• -p Inverter TCP port (default: 1470)
• -s HTTP server port (default: 8100)

Example:

./aurora-go -r 192.168.1.133 -s 80

On start you’ll see:

Inverter IP:PORT : 192.168.1.133:1470
Simple Data URL : http://localhost:80/
Json Data URL   : http://localhost:80/json/
XML Data URL    : http://localhost:80/xml/

• / Plain text summary
• /json/ JSON payload
• /xml/ XML payload
• /health/ Health probe: performs a lightweight status query and returns OK or ERROR (HTTP 503)

The TCP client uses timeouts and deadlines for write/read, reads exactly 8 bytes per Aurora frame, and retries with exponential backoff. If the inverter goes to standby (e.g., at night), requests will fail fast with ERROR and will automatically recover as soon as the inverter is back, without restarting the process.

• Cannot connect / timeouts: verify IP/port, firewall rules, and that the inverter’s TCP interface is reachable.
• Frequent ERROR at night: expected when the inverter is in standby; it will recover automatically in the morning.
• Health check: curl -i http://localhost:8100/health/ to quickly verify connectivity.
