Semmy

Personal Solar Energy Monitor

Supported inverters

Out-of-the-box support is provided for StecaGrid inverters that have an Ethernet interface and web portal with a "Measurements" page. If your inverter does have an Ethernet interface, but no such page, then you need to update the firmware.

Semmy is intended to be completely extensible. You can add support for other inverters by implementing the Inverter contract. Hook it up in the InverterServiceProvider and feel free to send a pull request.

Supported logging portals

Semmy currently supports logging to PVOutput.org and Sonnenertrag.eu.

You can add support for other weather services by implementing the WeatherStationContract contract. Hook it up in the WeatherStationServiceProvider and feel free to send a pull request.

  3. Add the following to your crontab:

Semmy also provides a real-time web dashboard that shows the current status of your solar generation and current weather conditions. In your web server, set the document root and index to public/index.php and be sure to enable rewrite support.
