Try setting the maximum connection lifetime. https://github.com/mill1000/midea-ac-py?tab=readme-ov-file#resolving-connectivity-issues

I made the change you mentioned. Still getting the intermittent unavailable. Sometimes it stays unavailable then I have to restart the integration a couple of times.

I have also included a debug file that I recorded when the integration become unavaialble.

Can you keep debugging enabled and restart HA? I can't quite follow what happened to your device but it appears to be rejecting the authentication process.

I did a reboot with debugging enabled home-assistant_midea_ac_2024-10-16T08-14-28.355Z.log

Thanks. Some disconnects are occurring on a 60s interval. Try reducing your connection lifetime to 45 seconds.

I will try that and monitor. I will keep you posted
