"MQTT in" Topic and kontext

Is there a way to fill the topic field from the flow context?

this would make maintenance much easier if you only had to change 1 konext instead of 5 nodes per flow

Welcome to the forum. The standard mqtt-in node does not allow it. If you search on flows.nodered.org you’ll find a few contrib nodes that already provide a dynamic mqtt subscriber node



that's how it works. thank you
