Got it working with my Ender 3 v2, had some issues showing actual temp but this: https://community.octoprint.org/t/temperature-reporting-now-working-with-new-ender-3-v2/21053 fixed that.
OctoPrint is telling me an update is available, but when I update and restart OctoPrint. I get to the login screen, but when I log in I am unable to access the WebUI. Telling me it might be overloaded or something is wrong.
