Service to listen UDP multicast messages from SMA devices and forward the information to a MQTT server.

This is an under-development work, so the configuration options may change at any point. See the config/default.json file to check the available options. They should be self descriptive. See the config module documentation to get the information about how to change the options (or just edit the default file).

The service published a MQTT message every mqtt.period seconds to mqtt.topic topic. The message contains a JSON with the following format information:

• samples. Number of UDP messages received and correctly parsed since last publish.
• grid_w. Average power consumed from grid during the period in W.
• grid_wh. Grid energy consumption counter from last received message in Wh.
• feed_w. Average power feeded to grid during the period in W.
• feed_wh. Grid energy feed counter from last received message in Wh.

The service can be run using Docker. The image can be found at Docker HUB. Example to run the image with a custom config file (home.config.json):

docker run -it --rm --net host -v home.config.json:/usr/src/app/config/home.json -e NODE_CONFIG_ENV=home metbosch/speedwire-to-mqtt
