Support for Smart Air Purifier 4 no longer works

[sasojadrovski]

Describe the bug
Since a few days ago, Homebridge continuously reports issues with the Smart Air Purifier 4. It looks like Homebridge cannot connect to the device. I did try with forcing Mi Cloud, but the issue persists.

Expected behavior
Smart Air Purifier 4 should work as expected.

That might be a strong indicator that the token changed. You would need to re-fetch the token.
Also if you specify forceMiCloud then you also have to specify the account credentials for login.

Thanks @merdok,

How do I re-fetch the token?

I know I have to add my credentials if I force using Mi Cloud.

[merdok]

Please check the README for the credentials!

The token you can retrieve as usual

Been having issues with the Xiaomi Air Purifier 4 Pro. Deleted and re-added and saw these lines.

Actually I woke up today and my two Air Purifiers in the Plugin disappeared. Had to add them back. After adding back, one of them, the 4 Pro showed that error.

So after a few tries I got it back. But there seems to be a bug with the "general device settings" where even when the controls are not selected, they still appear as part of the created device.

Please refer to the screenshots:

What would you expect to disappear? From your screenshot it looks as it supposed to...

What would you expect to disappear? From your screenshot it looks as it supposed to...

1. If you noticed in the first screenshot, none of those are ticked (selected). And they all appear. What I'm trying to do is simplify what I see in Apple Home, which is without the screen toggle options, while maintaining the On/Off button, temperature, humidity, air quality and filter maintenance like my other air purifiers.

2. Or was it the case the functions will be automatically created and cannot be removed or customised to which the user prefer?

3. I forgot to mention another bug.
   So I set my air purifiers to turn on at certain time of the day e.g. 10am and 3am. So when they turn on by its automated instruction in Apple Home, 3/4 of the time the air purifiers will go into the max volume mode (volume 3) instead of going into auto mode by default when it's turn on (they are always on auto even before being automated to turn off).

[merdok]

Screen is a device specific setting so you will not find it under the generic section, but I guess under the air purifier section.

[arktiknova]

Oh yeah you are right. Just checked btw after you pointed it out but I don't have them ticked too. Basically everything automatically appeared even when they are not ticked (selected). Are those supports to appear despite not being selected?

[merdok]

You should try to tick it and save, and afterwards untick it, save again and re-check.

[arktiknova]

Finally got the time to give it a try. I did as suggested and it finally worked after two reboots. Thank you!

Edit:
However, I now noticed my second unit, the Xiaomi Air Purifier 2 now doesn't show the temperature and humidity data now after the two reboots (and a few more to make sure). Nothing was touched on that unit's settings.

Good to hear. About your other device you have to check what the log says, possibility it cannot connect to the device.
