Unsupported device found: deerma.humidifier.mjjsq

[TheLastProject]

Home Assistant commit 4d314ba4df, at time of writing the most recent commit of the master branch (home-assistant/core@4d314ba). I decided to run Home Assistant locally in a dev env on my Linux box to be able to debug the device not showing up in Home Assistant on my NAS to be sure it's not a token-related issue.

Feels weird to create this issue though because issue #40 and #43 exist which implies it should be supported?

Anyway, this is the error I got.

Any way I can help debug this? I would love to get this working and thank you for all your work on this integration :)

This custom component does support the device. The device isn't supported officially / be the core right now. You could compare these two files to get a better understanding what's supported:

https://github.com/syssi/xiaomi_airpurifier/blob/develop/custom_components/xiaomi_miio_airpurifier/fan.py
https://github.com/home-assistant/core/blob/dev/homeassistant/components/xiaomi_miio/fan.py

I see, thank you so much for the explanation! Sadly I'm having trouble getting the token. The old app version Home Assistant seems to recommend doesn't seem to be able to find the device.

@Frix-x @forhuan @xia0linz1 @tehnoinstyle Could any of you tell me what app version on what device you used to get the token for deerma.humidifier.mjjsq? Home Assistant's documentation recommends 5.4.49 but that version doesn't recognize the humidifier.

Once I do have the token I'll communicate back if it works properly and if it does so I'll close the issue. I do wonder though, why are the fan codes so different? Home Assistant seems to support a few devices that aren't supported here and the other way around?

I capture the https traffic to get the token.

I've used the "log" method:

1. Use the last MiHome app to configure and link the device to your account
2. Downgrade to MiHome v5.4.54 (very important, it's the only version containing the debug log enabled)
3. Start the app, connect to your account and wait for the app to download and initialize your plugins (and so you humidifier). Then you can close the app.
4. Open a file explorer, go to '/sdcard/SmartHome/logs/Plug_Devicemanager/' and open the file 'current-date.txt'
5. Find the token in the log. It should be in the Json format with other info from every devices linked to your account

This is by far the easiest method from my point of view !

Hi.

I use the modified Mi Home application from here: https://www.kapiba.ru/2017/11/mi-home.html

Last Version 5.6.82

In it you can see the token, and other information. (in the app menu)

I went for @Frix-x's solution. I wasn't aware you could do the setup on a newer Mi Home version and then downgrade to get the token. That's a huge headache save. Thanks all of you for your help!

Got it working now, closing this issue <3
