This solution demonstrates how the OCPP Gateway acts as a proxy between OCPP and MQTT, enabling integration with AWS IoT Core and downstream CPO services built on AWS.

aws-ocpp-gateway's Issues

Question: Using this gateway for production?

Hello,

I am building a CSMS server on aws and wanted to evaluate using this gateway in a production environment. I am a little confused with how to architect this (as my understanding with a few AWS services are at a novice level).

I will need to extend the message processor in the gateway code to support different topics other than heartbeat, bootnotification & statusNotification, right? Including all actions under ocpp 1.6 and 2.0.1 ? Or do we just create rules in in AWS IoT to route certain messages to a DynamoDb table?
Essentially this gateway should be extended such that all incoming messages are routed to DyanamoDb and there we can have Dynamodb streams to act on relevant/interesting topics OR would you suggest the message processor to route relevant topics (like startTransation) to an appropriate AWS service (responsible for handling it) OR should all the messages be pushed to SQS and then my AWS service subscribe to relevant topic to act on it?
To what extent is the ocpp library used here? How do we leverage it fully with the ocpp gateway?
Why would you recommend going for such a solution instead of building our own server?

Is it mandatory to use MQTT over Websocket on Charge point device or Just Websocket is sufficient?

Dear @galinsky ,

Thanks to confirm if it is mandatory to use MQTT over Websockets on Charge point device?

The communication between Charge point device and OCPP gateway can be based on Websockets and OCPP gateway internally uses MQTT communication with its internal services.

CreateKeysAndCertificate fails when deploying

I followed the documentation to deploy the stack to this point:

Here it keeps failing with this error:

Any idea what I am doing wrong? All steps (incl. bootstrapping) before worked out fine.
I am trying to deploy to eu-central-1 btw.

nodejs runtime error for Lambda during deployment

No module named RDPS

I tried to simulate a CP in Simulating CP connectivity step 9.
When running python3 simulate.py --url {websocket URL generated from the AWS OCPP Stack} --cp-id CP1 I get:
ERROR:root:VirtualChargePoint1: Waited 30s for response on .......

It turns out there is a missing import in the lambda function called: AwsOcppGatewayStack-OCPPMessageProcessor....

I tried adding rpds to the requirements.txt file and deploying it trough AWS, but it did not resolve the issue.

The program keeps reporting 400 errors

Hi，

When I changed the log level of the program to INFO, the program continued to output 400 errors. But no requests were actually made to access the server, and the errors were very frequent, close to once a second.

Thanks

What version of OCPP complaint stack is supported?

Dear @bigadsoleiman

Does the OCPP complaint Gateway on AWS IOT core supports OCPP version 1.6J or it is restricted to Ocpp 2.0/2.0.1 ? please advise.
