Are you sure this does what you think it does? This looks like a mutex to me and with this you're defeating the purpose of the mutex?

self.periodic_connection_running is just the current state of whether or not we have a current active connection.

self.stop_connection is the mutex-like that actually controls whether or not the connection SHOULD be stopped.

If stop_connection == False and periodic_connection_running == False, we need to restart the connection- anything else we just let pass through, because we're either already connected and should be, or stopping the connection and falling out of the while loop.

Hmmm it doesn't look like this. self.periodic_connection_running is just prohibiting multiple while-loops from running. With the change it will be possible to start it multiple times.

except RoombaConnectionError as error:
self.periodic_connection_running = False
self.on_disconnect(MQTT_ERROR_MESSAGES[7])
