HA loses access to aircons

Describe the bug （描述一下问题） A clear and concise description of what the bug is.

The addon works fine, can control ACs and if ACs controlled manually HA sees the updates. However sometimes 12 hours or 24 hours or anything random inbetween after HA started, I lose access to control them. I am able to change mode for example, and the entity updates to the new mode, but the actual action doesn’t happen. The devices never become unknown or anything.

When I restart Home Assistant, the issue is gone and I can control them again.

Almost like something in the state become out of sync and communication fail. Logs says 2022-02-21 15:59:40 WARNING (SyncWorker_1) [msmart.device] Got Null from 10.0.0.53:6444 Version: 3 Count: 0 Spend time: 0.01 Got Null? Why would a restart of HA fix this.

[mac-zhou]

1. modify the file custom_components/midea_ac/manifest.json, change msmart version to 0.2.1, like:

{
        "domain": "midea_ac",
        "name": "Midea Smart Aircon",
        "version": "0.2.0",
        "documentation": "",
        "requirements": ["msmart==0.2.1", "pycryptodome", "pycryptodomex", "click"],
        "dependencies": [],
        "codeowners": ["@mac-zhou"]
}

1. restart your HA

I am optimistic, it looks like my ACs have been 100% now for 48 hours. If it continues like this for the next few days I think this issue can be resolved.
