digitaltwinconsortium / iot-edge-ocpp-central-system

Azure IoT Edge Module implementing the Open Charge Point Protocol (OCPP) V1.5 and V1.6 Central System

Docker container implementing the Open Charge Point Protocol (OCPP) V1.5 and V1.6 Central System.

The Central System is a server responsible for communicating with charging stations and provides user authentication, billing and charge point reservation services. There is a companion dashboard project for this located here.

Deployment

docker run ghcr.io/digitaltwinconsortium/iot-edge-ocpp-central-system:main `

Configuration Settings

The MQTT broker receiving telemetry messages from this container is configured via environment variables:

• CreateMQTTSASToken - set to "1" to create a SAS token for authentication
• UseTLS - set to "1" to use secure MQTT (MQTTS, leveraging TLS)
• MQTTBrokerName - for Azure IoT Hub, this is the Azure IoT Hub Hostname
• MQTTClientName - for Azure IoT Hub, this is the Device ID
• MQTTUsername - for Azure IoT Hub, this is [BrokerName]/[ClientName]/?api-version=2018-06-30
• MQTTPassword - for Azure IoT Hub, this is the Device's Primary Key
• MQTTMessageTopic - for Azure IoT Hub, this is devices/[ClientName]/messages/events/
• Publishing_Interval - the interval in which OCPP telemetry messages should be sent to the MQTT broker

Additionally, the environment variable "RUN_TESTS" can be set to "1" to run a simulation of 2 charging stations sending messages to the Central Station in an alternating fashion which is useful for testing purposes.
