Formula and Tags

Formula and Tags

Hello,

What is the easiest way to use a tag value in a widget's formula feature? Is it possible or i should create a analysis just for that? If yes, do you have any demo?

Ideally I want to calculate a new data based on my device raw data and a constant value (which would be a tag for that particular device).

For instance:

device variable : x;

device tag:
Name: y, Value: 3568

BluePrint Device MyDevice
Variable: x

Formula on a specific widget: ($VALUE$ * y)


Thanks !
