Computed attributes, how to assign to devices?

I've created a fuel computed attribute

If I test it, it shows the correct number, but I can't find it in the "Chart Type" drop down. Do I need to assign it to the device? If yes, how?

Thanks

try changing the expression to this:

io89? io89 : null

if the data is not present, it ignores it and does not generate a warning in the log record.

But the data is there, if I test it, it shows the right number.
By the way I've tried your expression, but with no luck.

You have to link it first and then wait for the new data.

Exactly my question: how do I link it?
I don't see "calcualted attributes" in the devices setup as Cristian:

Cristian provided you with the screenshots for linking.

Andrea, in the icons on the right in the list of devices you should choose "connections", you are selecting edit device.

Thanks @syztan , I've missed the "connections" in your first screenshot.

P.s. Anton how can I mention a user?

You can just write their name?

Oh, as simple as that?!
Let's try: hi Anton Tananaev!

I feel like what you were trying to ask is how to notify any specific user, not how to mention. The answer to that is there's no such option. If you just want to mention a person, you can simply write their name. If they subscribe to a thread, they will receive a notification.

I haven't understand what you wrote, sorry.
You say that it's not possible to mention a person, but after you say that to mention a person I simply write their name (which it didn't work for you).

How did you mention Cristian?

I just wrote the name in bold. You can write any text in bold. See markdown docs.
