Hi,

I’d like to have a script in designer which gets triggered on all tags with a specific name (each device would have one).

Is this possible using the Gateway Event Scripts → Tag Change ?

My script triggers on a specific tag, or all tags with `[MQTT Engine]*`, but I need some kind of blanket rule or wildcard selection that allows me to trigger on a specific tag name.

Ideally I’d like to specify something along the lines of `[MQTT Engine]*/*/*/*/ExecCommand`, this did not appear to work, should it?

I’m planning to use it to filter comand requests depending on permissions.

No, you can’t configure the listener that way. What you _could_ do (I’d be wary of the performance ramifications, though) is configure a broad listener, and then _immediately_ in your script do the check for the final element in the tagpath - and if it’s not found, finish execution. I’d recommend using `if event.tagPath.itemName == "ExecCommand":` or something similar.
