I've downloaded a few flows that contain other people's broker MQTT broker IP addresses. (I use Mosquitto, by the way)
When adding the MQTT node into a flow I now have a growing list of broker IP's appearing in my dropdown selection list - so I would like to remove them.
Some choices are actually my usual broker but with a different Will message. It seems to create a new broker if the will message changes.
Disturbingly, one of my flows is choosing another address in the list and adopting it as it's broker. This a bit of a concern for me because I am expecting messages that never arrive. When I check on the broker - it's a different one to the one I have saved previously.
I don't see any logical way to remove them from the flow window (settings etc.)
Is this a Mosquito problem - or a node red cache problem?
Any help would be appreciated.
