I'm running Node-RED under Docker. In my flow, I want to subscribe to MQTT topics. The MQTT broker server should be read from the ENV vars:
My broker only accepts connections via websocket (like
ws://[ip-address]/mqtt). But the mqtt-in-node reads them as a string:
Any ideas on how to fix this?
This only works if it replaces the entire property - it cannot be used to substitute just part of the value. For example, it is not possible to use
Ah it works! It also seemed like my docker-compose file didn't really create the environment variable which was also causing confusion.
Nevertheless, thank you
