Module Development

In tag managed tag provider there are function to update V,T,Q, But how to process if I want to update only the tag Quality ?
Read the current value and then update Quality and value ?

Yes, you should just read or hold a reference to the current value. ManagedTagProvider ultimately delegates to MemoryTagValueActor, which only accepts a QualifiedValue.

I was looking for a kind of single source of truth for the value, before keeping a copy of the value for each tags in my module…

Generally the assumption with ManagedTagProvider is that there already is some external source of truth, and you just want to make that available to Ignition to consume as tags.

Yes it make sense.
