[MQTT Plugin] How to get the topic?

[mlazze]

Hello,

i have setup an Action which triggers by "MQTT Action-Trigger" and causes "MQTT Action-Type Store Data" to fire.

I'm using a debugging payload parser, to check what's being sent and the available globals:

console.log(payload);
console.log(this);

payload = [];

Here's what's being logged:

[22:10:34] Log from payload parser: 237.1
[22:10:34] Log from payload parser: {
    "payload": 237.1,
    "raw_payload": 237.1,
    "device": {
        "id": "6159fee2eeb93a8c0fa57097",
        "tags": [],
        "params": []
    },
    "console": {}
}

So, in "payload" i'm only getting the value, with no reference to the mqtt_topic.

I'm also using the cloud tago.io service, with a similar setup i always get metadata.mqtt_topic in the payload, but in tagocore mqtt plugin i only get the value.
I could add different devices for each topic, but there should be a better way.

The problem is in mqtt plugin, replacing

n&&(n.metadata=ae(se({},n.metadata),{mqtt_topic:r.topic}))

with

(n="object"==typeof n?n:{variable:"payload",value:n})&&(n.metadata=ae(se({},n.metadata),{mqtt_topic:r.topic}))

in /var/lib/tagocore/data/plugins/7c713c7aace7bda2583a1cb19e873d02/build/index.js solves the problem.
7c713c7aace7bda2583a1cb19e873d02 is the mqtt plugin id for my installation, please check it's the same for you when applying this.

Do you know if there's a repository for the mqtt plugin i can add a pr to?

Thanks
