I have an Old MQTT Broker on my Synology in Docker. I recently migrated to an HA blue and started using the MQTT add-on there. I still have devices connected to my old MQTT that I can not change.
How do I set up an MQTT bridge? Should I setup the bridge on the new add-on? I think I should but not sure how to edit the conf file.
I tried to set up the bridge on the old MQTT. It says there is a connection in both brokers, but I still can not control those devices on the old MQTT.
However, since you have the mqtt broker already on your NAS, why not just continue to use it with your HA Blue? That way, you don’t have to have a bridge at all. Seems to me to be the path of least resistance.
