Device selector for "pm25" attribute of new Ikea Matter Air Quality device

[pfmiller]

What is the device selector parameter for the "pm25" attribute of new Ikea Matter Air Quality devices? I've tried "capability.pm25", "capability.pm25Sensor", "capability.pm25Measurement", and various others and none return any devices.

There isn't one; those are for capabilities, but this is a custom attribute (as there is no such capability). You will need to use something else the device supports, such as "capability.airQuality".

What you pick doesn't matter in terms of what you can do with the device, in case you are wondering; it's just a way to get it selected.

This is a very useful app that I use :

[BETA] Device Details Display Utility

In delving into the way that device drivers are constructed for HE I found myself bouncing from page to page to wrap my head around the details particularly if I was trying to look at 2 or more devices. To speed up my analysis I wrote a series of small apps, that I finally decided to consolidate into one slightly bigger one that gave me all of the details about a device in one place.

bertabcd1234 Wasn't sure if I was missing something. The airQuality capability doesn't seem to exist for the device either for some reason, but carbonDioxideMeasurement does so that'll do!

kkossev That's super useful, thanks!

Sorry, you're right! (I was going by memory.) That is a custom attribute on this device too because it only reports one of a few discrete values, not an actual AQI as the capability was designed for.
