A discovery rule creates an item for each file in a directory with a name like 00000034B4A5.
I wanted to override the item name by using a host macro, so I created:

{$SENSOR_00000034B4A5} = "Temperature Sensor 1"

Then, in the item name, I tried to use an LLD macro like this:

{$SENSOR_{#SENSORID}}

However, Zabbix does not resolve the macro dynamically. It displays the string {}{$SENSOR_00000034B4A5}{}.
