Display computed attribute

Hello,

I created a computed attribute but I don't understand how to display it on a device
I would like to display the computed attribute on the map with the details of the device (if possible) on on reports
It is for fuel level which is io390 but I need to divide by 10 to have the right value

First of all, have you checked if the computed attribute is working correctly?

Yes I try on a device with the test section and 420 has a result of 42

1. OK, have you linked it to the device?
2. Do you see the value in "more details"?

1. No I don't find how to do it
2. No because 1. not

Now link to the device but not seen in "more details"

You need to wait for the new data. Make sure you read the official documentation:

ok thanks for your reply
it is possible to have directly on the device : not in more details?

Yes. You can configure it in preferences, but have to make sure it's working first.
