The new Onelink Smart Smoke + Carbon Monoxide Alarm replaces First Alert’s original HomeKit smoke alarm (reviewed) with both wired and battery versions available to order. In addition to working with HomeKit and Alexa, Onelink includes voice alerts that tell you what triggered the alarm (smoke or carbon monoxide) and where the alarm was triggered.
HomeKit support lets you receive alerts about smoke and carbon monoxide detection from the Home app, and you can create smart automations like automatically turning on smart lights and unlocking smart locks if the alarm is triggered. This can make evacuating easier during an emergency.
First Alert’s smart alarm can also sound off other compatible Onelink alarms:
The new entry-level Onelink smart alarm works with Alexa voice control from compatible devices like Echo Dot ($29.99, reg. $49.99) and Siri voice control from Apple devices.
