Hi! I installed OctoPrint-MQTT Plugin and I have 3 printers conected in diferents serial ports. The topic octoprint/event/Connected has "port": "VIRTUAL". The othertopics lists hasn't an attribute to identifiy a serial port, for example, the topic "octoprint/event/PrintStarted". How can I determine whose temperature it is? Who started printing?

Thanks!!

change the base topic for each instance to something different, ie Printer1, Printer2, Printer3.

Oh, so you move the USB cable from printer to printer and only have one octoprint instance?
