I have multiple edge nodes transmitting to a gateway via MQTT. Some of them seem to perpetually need a refresh which stems from [MQTT Transmission]Transmission Info/Refresh Required constantly becoming True some time after is is refreshed.  
As far as I know no new tags are being added or removed on the edge nodes. There are some scipts writing values to other tags but no tag creation is occuring. Can I check which tags are causing it to turn on through logs or some other means ?

This was one of the aformentioned tags yesterday, I refreshed it whenever I happened to see it. Notice how the time it takes for it to become True again is not consistent throughout the day but ranges from about 5 to 20 minutes.

I also read this post but didn't see any answers related to how you can investigate why it turns on.

Also, maybe this feature can help.

If a tag is reconfigured, I would expect it to also need refreshing. (Writing to tag properties or UDT parameters other than `.value` are **configuration**.) Do you have code that is enabling or disabling tags? Or dynamically reconfiguring them based on other tags?

Thanks for nudging me in the right direction it was a matter of system.tag.configure, after a lot of digging around I managed to find some ancient scripts that turned some tags on and off...
