If you would like apply provided fix:
pip3 install --upgrade git+https://github.com/rytilahti/python-miio@airpurifier_miot/fix/aqi_refresh
I will also test it by myself, but it could take a while (right now i have good weather condition and stable 1pm2, so I have flat chart with or without fix)
Unfortunately ended with several errors regarding dependencies etc, i am not sure HASSIO is the best way to test those
Irregardless, it appears a fix is being pushed for next release for the continuous monitoring. Based on the link you posted @Razer, so I will hold off trying manual fixes and just wait for that to surface.
No a fix is not coming
We have to test this to have it fixed
Sorry if I misunderstood, but appears it is being merged into main?
And until the merge happens, he proposed to test it out, specifically on other purifier than the one he owns.
We have to confirm it works, itās as it says āan attempt to fix itā, @maker3 said he is going to test it soon
EDIT: Not sure what happened, after attempting to test the fix yesterday I am not able to set fan speed anymore 
the entity disappeared
Are you on 2021.12.8? There are loads of issues with the Miio integration. I personally rolled back to 2021.12.7, because I lost the number entities.
And sounds good, I am not going to mess with my standard integrations, I wouldnāt even know where to look for the code as I suppose it is hidden for newbies like me.
That could be the problem
Whatās the easiest way to revert back?
I was successful with the following approach:
Configuration ā Add-ons, Backups & Supervisor ā Backups ā I clicked the one called core_2021.12.7 that was prompted to be created when I updated to 12.8.
Then I only checked the first checkmark, and clicked restore:
It didnāt give me any confirmation, so just be patient, as it is working in the background. On my Raspberry Pi 4 8GB it took 2-3 minutes before it rebooted.
Yeah i can confirm that was the problem, thanks 
Interesting, i donāt see any problems on my purifier proā¦ or am i missing something?
You still got the number entities, like favourite level? And they are not there, but disabled?
Might be specific to certain models.
Anyhow, a fix will be released after the latest release.
Well, i have two xiaomi fan entities:
āfan.mi_air_purifier_proā with only 7 attributes (original HA) and
āfan.xiaomi_air_purifier_proā with some 26 attributes (IMPROVED version) entity.
All there, nothing disabled or unavailableā¦favorite level switches ok, all seems to work like beforeā¦ i can change favorite level (and thus motor speed).
It can be model specific, though, sureā¦
There are devices and there are entities.
Do you have any working entities starting with number.xxx that are not disabled?
In my case one of them are called: number.bedroom_purifier_favorite_level
AHA! Found it. I have two, one is called ānumber.mi_air_purifier_pro_volumeā and other is ānumber.mi_air_purifier_pro_favorite_levelā. But i never used them, so i donāt even know what they are for.
In history first one shows all zeroes, so that one didnāt work even before update, but favorite level indeed died with latest update.
What is this sensor for anyway? I get my favorite level state from attribute in āfan.xiaomi_air_purifier_proā, thatās why all worksā¦
It is used for reading the current level and selecting another one.
OK, understood, thanks. But, as i said, i use another way to do it and since it works perfectly, iāll just stick with that option.
Thanks for explanation!
It seems that this issue has been resolved with latest HA update (12.9), since above two entitites are now ok and āaliveā in my HA.
Now we just need the PM2.5 value update interval fix to be released.
Hi everyone,
I canāt get this card wqorking. Itās also my first card so myabe i didnāt understand correctly how it works.
Anyway i copy pasted everything from the secondpost on the start.
Is there somewhere a simple step bij step instruction?
