Loss my AC after update to msmart==0.1.24

Describe the bug （描述一下问题） Hi, Mac.

After the last update to version msmart==0.1.24 (I updated on 12/01/2020), I get constant disappearing of my air conditioners. I see it in Logbook and History. There are no records of this in the Logs. Only once, right after the update:

Before that, on version msmart==0.1.23 this was not. Everything worked fine and stable for a few months.

@rokam I think I’m ready to roll back to v0.1.23, there are too many problems with UNAVAILABLE and this is causing problems for many people. What do you think?

hi…both 0.1.23 and 0.1.24 doesn’t work for me. any idea? tried to remove and reconnect usb module as well. no luck

just fyi, im using dongle EU-SK103

Dongle OSK-103 is more stable with midea app and you don’t have the unavailability problems but is not recognized from mac-zhou/midea-ac-py. I just open an issue for that.
