I'm also getting this error in the version 0.1.8 According to the OctoPrint documentation, the baudrate value isn't saved in the config.yaml by default, if set to AUTO:

# Use the following option to define the default baudrate, defaults to unset (= AUTO) baudrate: 115200

So the plugin will try to get that setting, but actually receives a None, which can't be formatted as a number, nor be connected to.

A possible "fix" is to select the proper baudrate from the connection panel and saving that (tick the checkbox) or setting the baudrate value to 0 in the config manually.
