SCPI 2.1.1 bridge

Talk to the SCN with an SCPI 2.1.1 backend

Modules

Only the following Charging Point interfaces are currently implemented:

• Credentials
• Locations (PULL from CPO)
• Tariffs (PULL from CPO)
• Commands (request start and stop of charging session incl. async result)
• Sessions (PULL from CPO)
• Cdrs (PULL from CPO)

Setup

Copy the example config file, editing necessary values:

cp src/config/config.example.ts src/config/config.ts

There are two config objects inside the config file, one for the SCN and one for the SCPI 2.1.1 backend.

Connect to backend

Once configuration is pointing to the correct backend (assuming TOKEN_A has already been obtained), we can do the credentials handshake with it.

node scripts/register.js

Connect to the Smart Charging Network

The SCN connection requires a TOKEN_A from the Smart Charging Network (SCN) node being connected to, as well as a registry entry pointing the Bridge's party credentials to the Smart Charging Network Node. To do the latter, all that is needed is a private key with funds to pay for a transaction on the network of choice (defined in the Smart Charging Network config).

Assuming the SCN config value dryRun is set to false, the following will attempt to create the connection between bridge and SCN.

TOKEN_A=abc-123 SIGNER_KEY=0x123...456 npm start

If successful stdout will show two requests made to the versions endpoint of the bridge. On subsequent restarts the two environment variables will no longer be needed.
