Looks like this is returning at least on Google Home Hub/Max: https://9to5google.com/2021/09/06/google-nest-hub-aqi/ https://9to5google.com/2021/09/06/google-nest-hub-aqi/ I've switched to use PurpleAir instead. It's likely the AQI on Google Home Hub/Max is also sourcing the data from PurpleAir. Disclaimer: I work for Google but not on anything this AQI related.
