Kepserver

For users of Kepserver we provide this format, which together with the message template can be used to send data via MQTT to Clarify.

Message template

When formatting messages in Kepserver, a message template must be used to specify how the payload is transmitted. Using this template will allow Clarify to parse the messages correctly.

[
    |#each VALUES|
    {
        "tagname": "|TAGNAME|",
        "timestamp": |TIMESTAMP|,
        "value": |VALUE|
    }|#unless @last|,|/unless|
    |/each|
]
