Please provide an example.

Class MyPublisher:
    def __init__(self, uri):
        client = MQTTClient(config={'broker': {'uri': uri}})

    async def start(self):
        await client.connect()

Instead of passing the uri in connect (otherwise you would have to save the uri as a property).
See line 474, where you're setting broker_conf['uri'] = uri
