How do i extract charging consumption data from the charger ? do i need to modified the ocpp.json , and if yes how should i modified the ocpp.json file ?

i read from https://github.com/thingsboard/thingsboard-gateway/issues/1059 , current available ocpp features are BootNotification, Heartbeat, MeterValues and DataTransfer . I believed from the MeterValues we can extract the charging consumption data right if I'm not mistaken . How can i get that data , is there any configuration changes that i must made in the ocpp.json file ? Thank you

I would like to confirm whether the ocpp features like BootNotification, Heartbeat, MeterValues and DataTransfer etc already implemented or waiting for development since we find message like "IOT gateway is not available to handler the OCPP call request". Thanks.
