Components in Utilitarian

Utilitarian API

The main application for Utilitarian. It stores all data and handles all scheduling of reading jobs. We provide a REST API to manage the data and jobs.

docker pull quay.io/pwit/utilitarian:version

See component settings on how to configure Utilitarian API

DLMS UDP Server

A high throughput UDP server to receive DLMS DataNotifications from meters.

docker pull quay.io/pwit/utilitarian-dlms-udp-server:version

DLMS Processor

Many DLMS push messages are encrypted and to decrypt UDP messages in the receiving server would reduce throughput and we could loose messages if the server is not available to process them. Instead the UDP server sends the DLMS messages to the message broker and they are consumed by the DLMS Processor where they get decrypted and parsed into Meter Readings that is published back to the message broker.

docker pull quay.io/pwit/utilitarian-dlms-processor:version

Utilitarian Poster

docker pull quay.io/pwit/utilitarian-poster:version
