fronius2mqtt

A Fronius HTTP API to MQTT bridge

Attention: This is a complete rewrite of the bridge. While the old fronius2mqtt brigde used polling the inverters to fetch the data, the new version make use of the push feature provided by Fronius Symo.

The daemon offers no HTTP endpoints which can be configured in the configuration interface of each inverter. It forwards the data directly to MQTT.
