Grid eXchange Fabric Documentation

COSEM

COmpanion Specification for Energy Metering, defines a set of objects to exchange data with Smart Meters using DLMS protocol.

DLMS

Device Language Message Specification, the protocol used to communicate with Smart Meters and other smart grid devices.

DSMR

GXF

Grid eXchange Fabric, formerly known as the Open Smart Grid Platform (OSGP). GXF is an open, generic, scalable and independent 'Internet of Things' platform, which enables various connected smart objects in the public space to be easily controlled and monitored. The GXF project is built using open source tools and standards.

IEC61850

IEC 61850 is an international standard defining communication protocols for intelligent electronic smart devices at electrical substations. See [IEC](https://www.iec.ch/smartgrid/standards/)

LMD

Light Measurement Device, a smart grid device which uses up to 4 light sensor arrays to determine light or dark for several areas.

MQTT

MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. See [MQTT](http://mqtt.org/)

OSGP

Open Smart Grid Platform, see GXF.

OSLP

Open Street Light Protocol, the protocol used to communicate with SSLD and other smart grid devices.

PSLD

Public Street Lighting Device, a smart grid device that is used to control and monitor a single street light.

SOAP Webservice

The open smart grid platform offers a Spring Framework SOAP Webservice.

SSLD

Sub Station Lighting Device, a smart grid device that is used to control and monitor public lighting (several street lights) and tariff switching for an area.
