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
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.
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
