This is IKEA’s “premium” sensor in the lineup at about $30, and it’s the weirdest mix of useful and confusing. It measures PM2.5, CO2, temperature, and humidity, but Apple Home doesn’t expose temperature for some reason. In Homey Pro it’s more complete, and you can even disable the display—just know it’s not battery powered and doesn’t include the USB-C cable.
