##--------------------------------------------------------------------
## Gateway OCPP
##
## Add a OCPP-J gateway
##--------------------------------------------------------------------
## Note: This is an example of how to configure this feature
##       you should copy and paste the below data into the emqx.conf for working

gateway.ocpp {

    ## When publishing or subscribing, prefix all topics with a mountpoint string.
    ## It's a way that you can use to implement isolation of message routing between different
    ## gateway protocols
    mountpoint = "ocpp/"

    ## The default Heartbeat time interval
    default_heartbeat_interval = "60s"

    ## The backoff for hearbeat checking times
    heartbeat_checking_times_backoff = 1

    ## Whether to enable message format legality checking.
    ## EMQX checks the message format of the upstream and dnstream against the
    ## format defined in json-schema.
    ## When the check fails, emqx will reply with a corresponding answer message.
    ##
    ## Enum with:
    ##  - all: check all messages
    ##  - upstream_only: check upstream messages only
    ##  - dnstream_only: check dnstream messages only
    ##  - disable: don't check any messages
    message_format_checking = disable

    ## Upload stream topic to notify third-party system whats messges/events
    ## reported by Charge Point
    ##
    ## Avaiable placeholders:
    ##  - cid: Charge Point ID
    ##  - clientid: Equal to Charge Point ID
    ##  - action: Message Name in OCPP
    upstream {
        topic = "cp/${clientid}"
        ## UpStream topic override mapping by Message Name
        topic_override_mapping {
            #"BootNotification" = "cp/${clientid}/Notify/BootNotification"
        }
        reply_topic = "cp/${clientid}/Reply"
        error_topic = "cp/${clientid}/Reply"
    }

    dnstream {
        ## Download stream topic to receive request/control messages from third-party
        ## system.
        ##
        ## This value is a wildcard topic name that subscribed by every connected Charge
        ## Point.
        topic = "cs/${clientid}"
    }
