How to create an engine?

[xdien]

Hello kuzzle

• I'm trying to create an asset using the API. I have read the documentation here,
• In the input parameter, there is a parameter called :engineId but in the documentation there is no mention of creating an engine? Is it a paid plugin?
• Is there any example to create engine?

Thank you

Hello, we are currently working on a new documentation that will be much more precise on how to initialise the device manager plugin.

But you should be able to create an engine using this piece of code.

this.app.sdk
      .query({
        action: 'create',
        controller: `device-manager/engine`,
        group,
        index,
      })
      .catch((error) => {
        this.app.log.error(`[${index}] Cannot ${action} ${plugin} engine: ${error}`);

        throw error;
      });

The device manager is an open source plugin, there is no need to have a paid plugin to setup engine

Thank you @rolljee . I hope the documentation is completed soon and has more examples.

I tried successfully creating the engine, then I created the asset, maybe I created the correct json content body

POST http://localhost:7512/_/device-manager/models/assets
Authorization: Bearer xxxx

{
    "engineGroup":"esp",
    "model":"Distiller",
    "measures": [
        {
            "name": "temperature",
            "type": "float"
        },
        {
            "name": "humidity",
            "type": "float"
        }
    ]
}

But the server responded back error, I know index, but I don't know collection and targets on the url?

I was able to create the asset but the error was because I filled in the wrong engineGroup

"engineGroup":"esp",
