11/19/2025, 1:54 PMHi, I wanted to make 2 standalone flows 1 that pushes the data from the historian to a websocket and the other to SQL. But I noticed only 1 at a time can be active. When I disable one the other pick ups. But there is always 1 with 0 input.
I am working with an instance of umh-core on v0.43.1.

Jermuk
11/19/2025, 2:58 PMthere is some config option that sets like client id or something
Jermuk
11/19/2025, 2:58 PMif this is the same and not unique, then they will share the same state of what has been read

input:
uns:
umh_topic: umh.v1.Gullegem.._historian.
So I should set a consumer_group on both so they have a different one, because they will default to the same in a stand alone flow?

i think it would be nice to note that in the documentation

11/27/2025, 11:49 AMwe will do something better: put it in the UI with a warning if you dont set it specifically.
it is technically in the documentation, but the documentation is also big and we dont expect everyone to always search through the full docs
