HA with multiple instances of octoprint

[turboc1208]

I have multiple 3d printers each running on their own octoprint servers. When I configure them both with my mqtt broker, they overwrite each other if two printers are on at the same time. In other words, I can have two instances of octoprint on connect one to a printer and d the connected status goes to connected. I can connect another printer and the status stays connected. If I disconnect either printer from octoprint the status goes to disconnected even though one is still connected.

Can the topic be adjusted to allow for multiple octoprint installations?

There are settings to set the topic and you can set that to whatever you want per instance.

Ok, how does HA know that those are octoprint entries If I change the name from octoprint to something else?

If you use the HomeAssistant Discovery plugin it will help.
