Meeting Notes:

7 February 2024

When to send signed meter values

• End of the transaction is most logical.
• Looks like code currently does not store values in the DB.
• An libOCPP API change is needed to merge the signed meter values pull request.
• The is an existing old pull request that also provides such a change.

DB Migration tools: See issue: https://github.com/EVerest/libocpp/issues/450

• List of tools to investigate:
  • https://sqitch.org/
  • https://contribute.liquibase.com/extensions-integrations/directory/database-tutorials/sqlite/
  • https://gitlab-com.gitlab.io/support/toolbox/upgrade-path/?current=14.4.3&distro=docker&edition=ce
  • https://atlasgo.io/getting-started
• Action Item: Robert will ask LFE for tools used in other projects.

Status OCPP 2.0.1 development:

• Shared sheet is not updated. Current coverage is getting to 100%, but that is not reflected in the sheet as agreed.
• OCTT takes about 2 days to run all tests manually, API for CI/CD integration not yet available
• Action Item: Robert will ask OCA about potential license issues with OCTT running in LFE build pipelines.
