if you leave your mi air purifier 2 in auto mode you will find that it spend most of its time is low power Consumption mode. so after playing around with the automation settings i have what i think are the best settings.. This is a step by step guide to how to make your purifier much more responsive. basically setting a trigger for it to come on and setting a trigger for it to turn off.

the first thing you need to do is set your favourite mode to something comfortable, so its just powerful enough not annoy you. you do that by holding down the favourite button in the app for 3 seconds.

now we need to set a trigger so that the purifier powers on in favourite mode at 25 MP2.5
1, click on the 3 dots in the top right hand corner

2, click automation

4, Click on "if"

5, then click the mi air purifier

7, now change it to 25 and click done
8, now click under "then" where it says turn on

9, then change it to "switch to my favourite mode"

now we have just added the first trigger, this will turn on the purifier when it gets to PM2.5 - 25 instead of the default settings which makes it sit in low power consumption mode for most of the time.

now we create a second trigger that idles in it auto mode when it gets to below PM2.5 -15

1, click on the 3 dots again

2, click automation
3033561.jpg3, click the + in the top right hand corner

4, click "if" and select the air purifier
3033561.jpg5, click "if below", it will be in chinese

6, change to 15 and click done
3033561.jpg7, Click turn on
3033561.jpg8, click switch to auto mode

9, click okay

this it done now, you should notice the air purifier is much more responsive and turns itself on and off far more often. obviously you live in a different environment than me so change the sensitivity to suit your needs.

    Do you have a more in-depth version of these instructions?

    Do you have a more in-depth version of these instructions?

    it changes the air purifier to switch to favourite mode when it reaches 25 PM2.5, it then switches to auto mode when the particle level gets below 15 PM2.5 (it will idle in low power mode). this means the air purifier switches on and off more frequently throughout the day. ive had my air purifier for months and it was in low power mode all of that time because i left it on auto mode, instead of making automatic triggers., with these triggers it turns on and both every 30 mins or so when the air level gets height,

    all my triggers are:

    below 15 PM2.5 - switch to auto mode and idles in power power consumption
    above 25 PM2.5 - switches to favourite mode, this will be powerful enough to get the air quality down to below 15PM2.5
    below 75 PM2.5 - switch to favourite mode - this will ensure it doesnt switch to idle mode to soon.
    above 75 PM2.5 - switch to auto mode, when auto is above 75PM2.5 will clean faster than my favourite setting speed (edited)

    Good write up of the instructions mate, I admit not having one I have no clue what the hell any of that actually is but they look pretty idiot proof.

    Now he $64000 question, how good are these air purifiers? Between the Mrs and the youngest they can clear a room with their farting (not even joking).
