The community can contribute to the source code in the form of feedback, raised issues,…
The Public Test Environment of the Open Charging Network has now gained a second publicly usable OCN Node.
Developers that want to test their OCPI services against the OCN can connect to it from today on. This supports the OCN community to also test the routing mechansim of OCPI messages between different OCN Nodes.
The new node is available under https://ocnnode.elaad.io/ https://ocnnode.elaad.io/.
Please follow the instructions for Connecting a service https://shareandcharge.atlassian.…
We have been working hard over the last few months to provide a secure Open Charging Network. Our focus has partly been on developing message signing and verifying functionality. Today we can introduce our method for enabling secure message transfer across the network.
As message signing may be a new concept for some, we aim to introduce it slowly. Right now, in the node provided in the public test environment, message signing is optional.…
The OCN Client project has been renamed to OCN Node, based on community feedback. This rename was done to avoid any confusion over existing client-server architectures.
Changelist from rename:
New registry contract address on public test environment
0x0A5f27Ee1EbDC68034aDbd9446F9375783aeF7DC
registry methods renamed:
updateClientInfo => updateNodeInfo
clientAddressOf=> nodeAddressOf
clientURLOf=> nodeURLOf
/ocn/registry/client-info endpoint renamed to /ocn/registry/node-info
Today, we have launched the first public test environment for the OCN in its current state of development. Charge Point Operators, eMobility Service Providers and any other interested parties are invited to connect and test their own electric vehicle charging products against it. Just follow these four simple steps on our Developer Resources https://shareandcharge.com/developer-resources/ page to get started.
