Hey all,  
I’m attempting to use Tag Change Gateway events with the MQTT Engine Module.

Essentially we have several devices that communicate their data via MQTT and we want a log of how many signals we receive per hour. I’ve written a script to gather these and count them up.

The Ignition Manual says the Tag Paths can have wildcards  
[MQTT Engine]application/4/device/xxxxxxxxxx/rx/\* works fine, and can pull in a tag.

But I want a wild card in the directory itself as we may add many instruments later and I don’t want to manually add all of their names individually if possible  
[MQTT Engine]application/4/device/+/rx/+  
Note: I replaced the \* with a + in this example as it italicizes

But this doesn’t seem to work, is there any work around people have

The wildcard only works at the end of the tag path.
