First Alert’s Onelink HomeKit Smoke + CO Detector drops to $82.50 (Reg. $120)

$120/$82.50

Amazon currently offers the First Alert Onelink HomeKit Smoke and Carbon Monoxide Detector for $82.33 shipped. Having just dropped from $120, like you’ll find at Best Buy, today’s offer is good for a 32% discount, beats our previous mention by $5, and marks a new Amazon low. This hardwired alarm from First Alert can monitor the presence of both smoke as well as carbon monoxide and integrates with HomeKit, Alexa, and more for sending notifications and the like. Plus, if there are any other alarms in your home, Onelink will be able to monitor and report on their activity, as well. Rated 4/5 stars.

For those who don’t need the HomeKit support, there are plenty of ways to grab a smoke and carbon monoxide detector for less. First Alert’s Z-Wave model only runs $37 at Amazon, and will still offer smartphone notifications and the like.

Our smart home guide is currently packed with additional ways to expand your setup, HomeKit or otherwise. If you’re currently relying on Siri, then Satechi’s Dual-Outlet Smart Plug at $40 is worth a look. Plus, there’s Arlo’s Ultra 4K Camera System bundled with a Video Doorbell for $378.
