Writing in a machine attribute to use in Node Red

[paul.genoud]

Hi All,

We have a use case where we want to write boolean into a machine attribute and to use this machine attribute to run a flow in Node Red (running on an EDGE IO).

The machine attribut we are using is a boolean. We want to send the data TRUE thanks to a button in an App and get the data TRUE in Node Red.

The issue that we have is the following :
When we press the Button in the App, we have an error message.

Here are the Config of the Machine Attribut used :

My guess is that the problem comes from the Data Source.

Any help on what I should do ?

Thanks,
Paul

Why dont you write the value using the API?
You set up your machine as tulip API anyways…
