Reset your device. To do so, press the Test/Hush button on its face for about 8 seconds. You will hear 2 consecutive beeps. Upon release of the button, the light ring will flash green once and then it will pulse red. Your alarm is now factory reset and you can follow the in-app steps to set up the alarm.
My Carbon Monoxide Alarm with Indoor Air Quality Monitor does not show up in the list of devices. How can I fix that?
