There ‘Fair’ reading is your local area/city. It’s the outdoor data taken when you set your home location in the App - Setting your air treatment machine's home location. 

The indoor ‘Good’ reading is the area your purifier directly impacts. 

The two don’t correlate. It’s more of an indication to the air quality out of your home, compared to that of in your home 

Mr Dean is correct. If you want to set your machine to go off, why not use Auto mode. This option will trigger the machine when  a spike in bad is detected in-home air. 

Using Auto mode (Purifier, Heater and Humidify)

Hi. So I’m aware of how my monitoring works and my app and how to use it. you’ll notice I’m scrolled down in my app and that’s not the outdoor reading, which is featured on top. That’s my indoor reading which is reading fair while the graph contradicts it…..

Hi my machine IS in auto setting thanks….

Thanks for the feedback. I’m aware of how to use my app and the feedback and features it provides. The app actually lists the outside information at the top. You must scroll down to access the house information  and below that os the graph as you can see from the included pictures. So you are incorrect. This is a reading of my inside air quality and at the same time the graph is not reflecting the reading… that’s what I need help with. 

Hi @An44444. At first I was confused with the image, but your explanation makes perfect sense to me. I think the information here would help at a possible fix. 

'Power Cycling/Restarting/Resetting' the air treatment machine

I’d lean toward there being a mis-match of data.

If a reset doesn’t fix it, you’ll have to get on the line to Dyson and have them investigate the cause. 

The data on the LCD screen and the app wasn’t aligning. Out of sync for about 3 days. I reset it like above and it fixed it. Hopefully it does for you also.
