I have an issue where i have an MQTT totalizer tag that has history enabled, but the powerchart tag browser does not show the tag. I am using ignition’s tag historian module with a postgress DB and it seems to me like the tag does not log any values into the historian. when inspecting the ‘sqlth\_te‘ table, the tagpath for the tag is present but no data is stored in the data partitions. anybody have an idea what the issue could be?

tag config:

Don't apply history/scripting/etc. to the tags in MQTT Engine. Those tags aren't solid - they can actually just up and disappear. Make reference tags over in a regular tag provider, and do that stuff on the reference tag. See if that fixes it.

Also, if the totalizer is running in a nice steady rate, the Auto deadband style is likely keeping it from logging a point. Switch that to Discrete (even though yes, it's an Analog value..)
