Because it speaks Matter over Wi-Fi, the SAWF-08P commissions directly into Apple Home, Alexa, Google Home, SmartThings and Home Assistant without a bridge, and it tracks CO2 alongside temperature and humidity on a large display. The X-Sense XR0A-iR Wi-Fi Radon Detector answers with a higher owner rating and, more importantly, the radon sensing the SAWF-08P cannot do at all. Buyers who want a CO2 monitor that plugs straight into any major smart home platform should choose the SONOFF SAWF-08P Air Quality Monitor; buyers specifically worried about radon should pick the X-Sense XR0A-iR Wi-Fi Radon Detector instead.
