No Longer Able to Find Dehumidifers on Network

[mankyd]

Version of the custom_component

0.9.4

Configuration

Not sure what to put here - I installed via HACs, clicked "Add Device" in HAss, and then it failed to setup.

Describe the bug

I have two Midea "Cube" dehumidifiers. One was working for a long time. One is new.

They both changed IP addresses, and then nothing I was able to do could get them back into HAss. I tried as much as removing the integration via HACs, rebooting the whole machine, then re-installing.

I have confirmed their ip addresses (now fixed in the router).

Interestingly, just now , if I "excluded" the first one, the second one worked! This is new - before nothing could bring either of them online. However, now I can't figure out how to retry adding the excluded one back.

I still am unable to bring the new one into the system.

I can control both of them readily through Midea's "Smart Home" app, which I believe replaced the "MSmartHome" app?

Same. I uninstalled via HACs. Now it wont let me reinstall.

A little more context and logging:

At this point, both devices appear in my HA setup, but the second one is failing to actually resolve. If I click "configure", I can get the first to work, but the second shows the wrong ip, and when I correct the IP (more on that below) and click "next", it hangs for awhile, before stating: "Invalid username or password (Unable to get valid token for XXXXXXXXXX).

The following also shows up in my logs:

Actually, interestingly, I see several logs of it trying to connect to the wrong IP address in general. I know my dehumidifier is is at 10.0.0.66, but I see lots of logs where it keeps trying to connect to 10.0.0.126. Maybe this is the bug?

One last update: I was able to edit my .storage/core.config_entries to fix the incorrect IP address. It did not resolve the issue however. I still have the Unable to get valid token error.

Already have one Midea smart dehumidifier, and everything's fine with that one as far as HA is concerned. I bought another Midea smart dehumidifier yesterday, but this one is not being detected by HA. At this point I am afraid to uninstall the integration, as rumor has it that I won't be able to reinstall it.

[Aqua1ung]

Alright, I bit the bullet, uninstalled the MIDEA integration, and reinstalled back on. Old dehumidifier was detected just fine, whereas for the new one I had to specify its IP, and that did it.

Many thanks for a great piece of software!

I found a workaround, and possible a hint at what the bug is:

I noticed everytime I tried to add the second dehumidifier, it would come back with the wrong IP. I think Midea must be caching it somewhere incorrectly?

By removing the dehumidifier in the Midea app, and then re-addding it, this extension straightened itself out.

Specific steps I went through:

1. Remove the offending dehumidifier from Midea app
2. Re-add dehumidifer in Midea app
3. In Hass, use "File Editor" extension to edit .storage/core.config_entries and ensure that the ip address for the offending device is correct. [This step might not be necessary]
4. Restart Hass. [This step might not be necessary]
5. Open this integration and click "Configure" to re-configure everything. The IP address finally came back correctly in this step and everything worked!
