Consider mappings or options for displayed state

One use case for this are items bound to channels of type
system.signal-strength. Those are number items with a default pattern of
%0.f and options mapping the valid values 0..4 to descriptive strings.
Show those descriptive strings (e.g. 'Excellent') if available instead of
the plain number value ('4').
