TagoCore (TAGOCORE_DATA)

TagoCore Support
1

I have Tagocore installed and running inside a Raspberry pi3.
The Integration with Tago-IO is running smoothly.
I need to work with the data inside Tagocore and for that I’m using a script invoked by the “Action” function, and this “Action” is also working.
At the moment I use the following support to access tagocore data through the script (https://tagocore.com/docs/analysis/code) This document points in its script an example of accessing the TAGOCORE_DATA environment.
My data array follows the proper model suggested by Tagocore/Tago-IO.
---------------------------------------------------------------------------------------------------------
PROBLEM: Executing the script returns an error in the Analysis console.
---------------------------------------------------------------------------------------------------------
This is the Scope data which is being sent by the device, the token of this device was place in the environment variable of Analysis
----------------------------------------------------------------------------------------------------------

[

{

    "variable": "temperature",

    "value": 16.5

},

{

    "variable": "humidity",

    "value": 74

}

]

----------------------------------------------------------------------------------------------------------
This is the suggested script:
----------------------------------------------------------------------------------------------------------

const data = process.env.TAGOCORE_DATA;

const temperatureItem = data.find((i) => i.variable === ‘temperature’);

console.log(“Temperature is at:”, temperatureItem.value);

---------------------------------------------------------------------------------------------------------

The error returned is:

---------------------------------------------------------------------------------------------------------

Finally:

.

If I run the script separately elsewhere without the line (const data = process.env.TAGOCORE_DATA;) it works correctly and returns the following: (“Temperature is at:” 16.5)

I would really appreciate your help from the community.

Hey @drcanalli

It seems like our documentation is outdated in this section, the correct example would be this one:

----------------------------------------------------------------------------------------------------------

const { Analysis } = require(“@tago-io/sdk”);

// The function myAnalysis will run when you execute your analysis

function myAnalysis(context, scope) {

// This will log the scope to the TagoIO Analysis console
// You can do anything you want with it

context.log(“my scope:”, scope);

}

module.exports = new Analysis(myAnalysis);

----------------------------------------------------------------------------------------------------------

Make sure you have the package @tago-io/sdk installed in your project.

I’ll make sure to update our documentation, and I hope this solves your issue!

Perfect Matt!

Yes, the problem was solved with your help.

Analysis running normally.

Thanks for the support.
