Thanks for the integration! Just wanted to report that I am getting the following warning from Home Assistant

I suspect that aiomqtt.Client internally does these blocking calls, but it might be able to use Home Assistant's utilities.

Depending how you want to proceed, I could take a look and see if I can resolve it?

Thanks for reporting this. Happy for you to take a look if you can. I won't be able to for a couple of weeks unfortunately.
