efergy-exporter is a simple server that uses rtl_433 to receive Efergy Energy data formatted to export via HTTP for Prometheus consumption, written in Node.js.
The voltage attribute it supplies to Prometheus is configurable.
docker create --name=efergyexporter \
-v <path to config>:/config \
-p 9122:9122 \
--privileged=true \
antilax3/efergy-exporter
The parameters are split into two halves, separated by a colon, the left hand side representing the host and the right the container side. For example with a volume -v external:internal - what this shows is the volume mapping from internal to external of the container. So -v /mnt/app/config:/config would map /config from inside the container to be accessible from /mnt/app/config on the host's filesystem.
-v /config- local path for smartexporter config file-p 9122- http port for webserver
It is based on alpine linux, utilising the official node docker repository with alpine tag, for shell access whilst the container is running do docker exec -it efergyexporter /bin/sh.
The container uses a single volume mounted at '/config'. This volume stores the configuration file 'efergyexporter.json'.
config
|-- efergyexporter.json
The efergyexporter.json is copied to the /config volume when first run. It has one mandatory parameter.
The mandatory parameter voltage should be set to either 110 or 240 this should be based on the voltage of your region.
