Open Source#

We want Utilitarian to be a simple companion to our customers in their AMR operations. We provide documented interfaces and APIs to our services and messaging system. So you have the freedom of making use of the data as you see fit.

For example if you need to make a special analytics service for some customers you can either get the data from the Utilitarian API or subscribe directly to it via the message broker.

We provide some helpers to write your own integrations written in Python but since we are using AMQP and HTTP you can find implementations of those protocols in many programing languages and use the documentation in our helpers to speed up development of your own integrations in your language of choice.

We also provide many libraries of the protocols we support as open source.

Utilitarian Helpers#

Utilitarian Queue Consumer#

Check it out on GitHub:

The Utilitarian Queue Consumer is a micro framework to write consumers for the messages in Utilitarian. It gives you good default for consuming messages and producing new messages.


Check it out on GitHub:

AMR UM (Unified Messaging for Automatic Meter Readings) is our attempt to have standard and well documented messaging framwork. In the repo you can find Python helpers to format the data and documentation on the different schemas used.



Check it out on GitHub:

DLMS/COSEM (IEC 62056, EN13757-1) is the global standard for smart energy metering, control and management. It specifies an object-oriented data model, an application layer protocol and media-specific communication profiles.

IEC 62056-21#

Check it out on GitHub:

IEC 62056-21 (earlier IEC 61107 or sometimes just IEC 1107, is an international standard for a computer protocol to read utility meters. It is designed to operate over any media, including the Internet. A meter sends ASCII (in modes A..D) or HDLC (mode E) data to a nearby hand-held unit (HHU) using a serial port. The physical media are usually either modulated light, sent with an LED and received with a photodiode, or a pair of wires, usually modulated by a 20mA current loop. The protocol is usually half-duplex.

I-FLAG / Corus#

Check it out on GitHub:

The Corus / I-FLAG protocol is used in Actaris / Itron meters. It is a propriotary protocol that have some elements from IEC-62056-21 but is using binary data of special formats to read out data.
