Hi, I've got a Midea AC unit and I've used this integration with mixed results. However, that is not due to this integration, but rather my AC unit I believe.
So why am I posting here? Because I hope that someone can help me with a solution..

This is my situation:

  • Running msmart-ng discover always discovers my device and gives the following output:
    {'ip': '192.168.1.138', 'port': 6444, 'id': 208......, 'online': False, 'supported': False, 'type': <DeviceType.AIR_CONDITIONER: 172>, 'name': 'net_ac_F714', 'sn': '000000P0000000Q1502DBB58F7140000', 'key': None, 'token': None}
    It says 'supported': False. I am not sure why it says that, because the integration works fine when it finds my device.
  • Sometimes my air condition unit is available for long or short periods, sometimes it is not. It tends to give authentication errors, but this is not the real issue as I am not connecting with the cloud.
  • I noticed that the IP address seems to change. I noticed this from running msmart-ng discover and checking the contents of home-assistant-config/.storage/core.config_entries. Sometimes this was a different IP address than what msmart-ng reported. Changing the IP and restarting HA would make the device work again.
  • You would think setting a static IP address would be an obvious solution. That is what I thought too and why I felt like I was going crazy. Turns out I am not entirely crazy, because..
  • I started writing down the mac addresses and IP addresses of all my devices and was starting to blame my ISP's router for not handling DHCP properly, until I noticed that the MAC address changed.. Currently I've noticed 2 different address, but I am not discounting the possibility that there's more or that it's randomly generated.

Anyhow.. Has anyone encountered this issue before?
Or does anyone have any advice?

Unfortunately I cannot map 2 MAC addresses to the same IP..

Finally, apologies if this is not the place for my troubles. I can always close the issue, but any help or thoughts would be appreciated regardless.

Hi there.

It says 'supported': False. I am not sure why it says that, because the integration works fine when it finds my device.

That's interesting. Can you run the discover command with the --debug options and post the output?

Sometimes my air condition unit is available for long or short periods, sometimes it is not. It tends to give authentication errors, but this is not the real issue as I am not connecting with the cloud.

This could be caused by a few things. One thing to try is the Maximum Connection Lifetime setting. The energy sensors have caused issues for some users due to their device not responding to the message.

Can't say anything about the MAC addresses. That's an odd one for sure.

Thanks for taking a look.

Sure:

I tried tuning the Maximum Connection Lifetime setting. But I am unsure what the recommended value is. I assumed it would be a longer value, e.g. 60 seconds, but I also saw something like 15 seconds. What do you recommend?

This is the bigger problem. Try setting a different cloud region or using another username & password.

Not sure is it is the same problem, but my "Midea" airconditioners stop woking a couple of days ago: they became not available (it happened a week ago too, and I thought it was because the IP addresses changed: I deleted them from HA integration, rediscoverd and they worked again) and, after deleted them, I cannot add anymore: Midea Smart AC HACS integration found them, but I receive the message "unable to connect".
So I tried with msmart-ng discover --region DE and it says:

`INFO:msmart.cli:Discovering` all devices on local network.

It finds 2 units, but they are 3 (yes, the third one is connected and available on the local network)

This is the output with --debug option:
