Testing with EVerest
In the case you don't have a charger that supports OCPP 2.0.1 to experiment with, we can recommend using the Linux Foundation Energy project EVerest. See here for the repository. They have built an open source version of charger firmware and also allow for using it as a simulator. They support OCPP 2.0.1 which makes it a great testing opportunity with CitrineOS. For the long route of setting up EVerst you can follow their documentation and build the project yourself. See here for Docs
Running EVerest
In order to alleviate some of the complexities that may arise when starting EVerest, we have created some helpful commands that should help in getting the EVerest charger simulator running locally and targeting CitrineOS.
You will notice in the apps/Server/everest directory the files created to support running EVerest within Docker.
In addition, we created some helpful package scripts (run from the apps/Server directory):
pnpm run start-everest— starts EVerest for OCPP 2.x (defaults toOCPP_VERSION=2.1)pnpm run start-everest-16— starts EVerest for OCPP 1.6
Both scripts cd into everest and trigger the docker compose up command (below) from within the
apps/Server/everest directory so that it can pick up the Dockerfile and the docker-compose.yml files.
You will notice that there are two args that are configurable:
EVEREST_IMAGE_TAG- The image tag that will be used for the EVerest image (ghcr.io/everest/everest-demo/manager).OCPP_VERSION- The version of OCPP to run EVerest for.start-everesthandles all 2.x versions for the given 2.xOCPP_VERSION, andstart-everest-16is for OCPP 1.6 only.
After running pnpm run start-everest (or pnpm run start-everest-16), you should see 3 running EVerest containers
and the manager container should have the appropriate EVerest logs.
EVerest UI
Now that the 3 containers are running in Docker, you should be able to navigate to [localhost|ip]:1880/ui/ to view
the EVerest simulator UI. There, you should be able to simulate the pause/resume and plug/unplug events among others.
EVerest NodeRed
You can also view the EVerest NodeRed UI [localhost|ip]:1880/, but it is not advisable to make any adjustments here
unless you have a good understanding of this configuration.
Viewing OCPP logs in EVerest
To view the OCPP logs in EVerest, we have utilized Node http-server, which you will see being initialized
in the Dockerfile. We initialize a simple HTTP server on port 8888 and expose this port so that it is
mapped in the compose file allowing you to navigate to localhost:8888. This HTTP server is configured to
serve the contents of the /tmp/everest_ocpp_logs which is where EVerest stores the OCPP logs in the
Docker container. Conveniently, the logs are in HTML format, so we can easily view them in the browser.
Running EVerest Manually
You can also use their demo repository that hosts a Docker packaged EVerest image. See here for Github Repo
To get EVerest running on the side while developing and making changes, you can follow the steps below.
- Run your CitrineOS instance locally with
docker compose up -din the CitrineOS repository. - Clone the EVerest Demo repository and
cdinto the repo. - With CitrineOS running execute an "add charger" script at
./citrineos/add-charger.shThis adds a charger, location and password for the charger to CitrineOS. - Bring up EVerest with
docker compose --project-name everest-ac-demo --file "docker-compose.ocpp201.yml" up -d. - Copy over the appropriate device model with
docker cp manager/device_model_storage_citrineos_sp1.db \ everest-ac-demo-manager-1:/ext/source/build/dist/share/everest/modules/OCPP201/device_model_storage.db. - Start EVerst having OCPP2.0.1 support with
docker exec everest-ac-demo-manager-1 sh /ext/source/build/run-scripts/run-sil-ocpp201.sh.
