[mill1000]

Does the device generally function or is it completely non-responsive?

It looks like you're running this integration (Midea Smart AC) along side Midea AC LAN which I would not recommend. We've seen issues before when both integrations are trying to communicate with the device simultaneously.

[DoerakkerHA]

I will disable the AC smart and keep an eye on it  Kind RegardsROnald Groeneveld Sent from my iPhone +31 650 989 689On 15 Sep 2025, at 18:25, Tucker Kern ***@***.***> wrote:mill1000 left a comment (mill1000/midea-ac-py#381) Does the device generally function or is it completely non-responsive?

I get a similar error, about 4 times a day, since a month or two:

2025-09-17 02:14:38.330 WARNING (MainThread) [msmart.lan] Send failed to 192.168.17.34:6444. Error: Error packet received.

Everything is working fine, no other related integrations installed.
This error did not occur before. It is does not correlate with any activity on the device.

Device: midea Portasplit

I'm not sure, if this is related. If it isn't please ignore.

[mill1000]

Can you enable debug logging and post the log when the error occurs?

[seanomat]

Sure:

My Timezone is +0200 at the moment with DST.
Let me know, if you need the whole log (it's a whole day and around 10 MB).

[seanomat]

The more I think about this, the more I suspect this to be a connection-issue.
I just reduced the reconnect interval to 1 hour. let's see.

[mill1000]

Gotcha, the other possibility is the authentication could be expiring sooner than expected.

I added the expiration on a bit of a whim (mill1000/midea-msmart#67) not because I knew exactly what the devices wanted.

[seanomat]

That makes even more sense.
The error in my case has not reoccurred.

Thank you for your service 😉
