A recent exploration of a test version of the Google Home app has revealed code strings suggesting potential support for carbon monoxide and smoke detectors, allowing users to receive alerts about hazardous air quality and sensor testing. Currently, the Nest app is the only platform managing these sensors, but integration into the Google Home app could create a more unified control system. The Matter 1.2 upgrade includes provisions for smoke and CO detector support, aiming to reduce the number of apps needed for device management. The timeline for the launch of a potential "future Nest Protect" remains unclear.
