Works With
A practical, budget-friendly smart smoke and CO detector best suited for Alexa users with existing Z-Wave hubs who want basic safety alerts without extra bells and whistles.
The First Alert Z-Wave Smoke and Carbon Monoxide Detector offers a solid, budget-friendly option for those looking to add smart safety monitoring to their home. It combines smoke and CO detection in one device, which helps reduce the number of alarms needed. Its integration with Amazon Alexa allows for voice alerts and some level of smart home automation, which is convenient for users already invested in Alexa's ecosystem. However, the device is limited by its lack of compatibility with other major smart home platforms like Google Home or Apple HomeKit, which could be a dealbreaker for some. The Z-Wave connectivity is reliable but requires a compatible hub, adding to the overall cost and complexity. Battery life is typical for this category, usually around 1-2 years, but replacement isn't as straightforward as some newer models with rechargeable batteries. It’s perfect for users who want a straightforward, no-frills smart smoke and CO detector integrated into an existing Z-Wave network, especially in homes already using Alexa. Those who want a more feature-rich experience with multi-platform support or easier installation might want to consider alternatives. Also, the alarm sound is loud but not as customizable as some competitors, which could be an issue in multi-story homes or for light sleepers.

Z-wave Smoke and Carbon Monoxide Alarm
Connectivity
Requires Hub
Z-Wave compatible hub
Full smart features require Z-Wave hub; no native WiFi or Bluetooth; no support for Apple HomeKit, Google Assistant, or Matter protocols.
Compared to the Nest Protect, the First Alert model is more affordable but lacks the advanced self-testing features and multi-platform support that Nest offers. Unlike the Kidde Smoke & CO Detector with Wi-Fi, First Alert uses Z-Wave, which requires a hub, whereas Kidde connects directly to Wi-Fi, simplifying setup but sometimes suffering from connectivity issues. The First Alert is a good pick if you already have a Z-Wave hub and want reliable integration, but if you prefer a standalone device with broader smart assistant compatibility, the Nest Protect or Kidde might be better choices despite their higher price points.
Installation is moderately easy, rated around 3 out of 5 in difficulty. It typically takes 15-30 minutes and requires basic tools like a screwdriver and possibly a drill for mounting. Pairing with a Z-Wave hub can add complexity, especially for users unfamiliar with smart home hubs. Professional installation isn’t necessary but could help if you’re new to Z-Wave devices or have a larger home network.
In daily use, the detector is generally reliable with quick response times to smoke or CO detection. The app experience depends heavily on your Z-Wave hub’s software, which can vary widely. Users report occasional connectivity drops, especially in larger homes with weak Z-Wave mesh networks. Battery life is decent, lasting about 1-2 years before replacement is needed. Alerts via Alexa work well but can feel limited compared to dedicated apps from competitors.
- Requires a Z-Wave hub, adding to overall cost and setup complexity
- Limited compatibility outside Amazon Alexa ecosystem
- Occasional connectivity drops reported in larger homes
- Battery replacement can be cumbersome
- Alarm sound not very customizable

Homeowners with a Z-Wave smart home setup seeking a combined smoke and CO detector with long-life battery and integration with Ring security systems.
Best purchased if you already have a Z-Wave hub or Ring Alarm system; otherwise, consider ecosystems with broader compatibility. Watch for sales during major smart home discount events.
Buy this detector if you already have a Z-Wave hub and use Alexa, as it integrates smoothly in that setup. Avoid if you want multi-platform support or a standalone Wi-Fi device. Pair it with other Z-Wave sensors to strengthen your mesh network and improve reliability. Don’t expect advanced app features or customizable alarms. Double-check your hub compatibility before purchasing to avoid connectivity headaches.
