Request for getting attributes with square bracket syntax

[Nestor]

Would it be possible to implement the set magic syntax [a:<device>:<attribute>]?
I'm now using Perl syntax {(AttrVal($DEVICE, $ATTRIBUTE, $DEFAULT))} which gets verbose quickly.

For example:

Code Auswählen Erweitern

([Aqicn_Brussels:APL] ne 'Good' or [Aqicn_Brussels:APL] ne 'Moderate')
(set Pu_Al msg title="Outside air is [Aqicn_Brussels:APL]" device="{(AttrVal('Pu_Lr', 'keyLr', ''))}:" "More info at {(AttrVal('Aqicn_Brussels', 'web_url', '?'))}")
DOELSE
(set Pu_Lr msg title="Outside air is [Aqicn_Brussels:APL] again" 
{('It was '.OldReadingsVal('Aqicn_Brussels', 'APL', '?').' for '.Time::Ago->in_words(OldReadingsAge('Aqicn_Brussels', 'APL', 0)))})

Second question:
is it correct that $DEVICE is only available when using [<devicename>:"<regex>"] syntax (evaluation of events) and not evaluation of reading like [<devicename>:<reading>]
In the previous example when trying to get $DEVICE or {($device)}, it appears to be unset, I would expect string: Aqicn_Brussels

You can use $DEVICE anywhere in the condition or in execution part.

$device is a perl variable. $device you can use only in condition.

Attributes in square brackets were discarded because they do not trigger.

It is not worth developing your own syntax.

Thanks for looking into it.
$DEVICE works now, I tested with set <DOIF-modul> cmd_<nr> and then $DEVICE is not set.

yes, $DEVICE corresponds to the real triggering device
