SimpliSafe Smoke & Carbon Monoxide Detector - 2-in-1 Home Protection

Our review finds the SimpliSafe Smoke & Carbon Monoxide Detector best for households that already use the SimpliSafe Gen 3 security system and want a compact, reliable way to detect two hazards with one device. The single biggest reason to buy is its 2-in-1 sensing and smartphone alerts, which combine early smoke and CO detection with real-time notifications and optional 24/7 professional dispatch. Installation is straightforward and the unit is engineered to ignore benign cooking smoke while still providing prompt warnings when danger is present.

Key Features

• 2-in-1 hazard detection: Combines smoke and carbon monoxide sensing so you need fewer devices to protect living areas.
• Instant alerts: Sends real-time notifications to your phone through the SimpliSafe app so you know about hazards even when you are away.
• 24/7 professional monitoring: With select monitoring plans the detector will trigger emergency dispatch from SimpliSafe's professionals for quicker response.
• Engineered to ignore cooking: Distinguishes between dangerous smoke and burning food, reducing false alarms from the kitchen.
• Built-in siren and Base Station trigger: Features an internal siren and will activate the Base Station siren for stronger local alerting.
• Easy setup: No wiring required; mount the included ceiling anchor and snap the detector into place in minutes.

Who It's For

This detector is ideal for homeowners and renters using the SimpliSafe Gen 3 system who want a compact solution that handles both smoke and carbon monoxide without adding multiple sensors. Families who value smartphone notifications and optional professional dispatch will appreciate the extra peace of mind.

It is less suitable for people who do not use the SimpliSafe platform or who require standalone hardwired detectors for specific building code compliance; those users should look for a hardwired or code-listed alternative instead of a wireless SimpliSafe accessory.

Pros & Cons

Pros

• Easy installation with no wiring and simple ceiling mount for fast deployment.
• Reliable connectivity and thoughtful system notifications keep users informed of status and issues.
• Dual-function sensor reduces the number of devices needed while maintaining early warning capability.

Cons
