Smoke, Fire and Gas Detectors

Smoke detectors, fire alarms & gas detectors

A smoke detector or gas detector is only truly effective if you can respond quickly. With smart smoke, carbon monoxide (CO) and gas detectors, you don’t just get a local alarm—you can also receive real-time notifications on your smartphone (model-dependent). That means you can be alerted even when you’re not at home and take action immediately. Within Smart Home, this is one of the most important safety categories: prevent, detect, and act fast.

Which detector do you need?

In this category you’ll find multiple types of detectors, each with a specific purpose. There are smart smoke detectors with features such as a high alarm volume (e.g. 95 dB), 360° smoke detection, and a mute button for temporary silencing. You’ll also find combo detectors that detect both smoke and carbon monoxide, and dedicated CO detectors with a display and threshold values (for example an alarm at 128 ppm) plus both an audible alarm and a visual warning light.

Gas detectors: monitor LPG and natural gas

For kitchens, boiler rooms, or areas with gas appliances, there are gas detectors that can detect LPG and natural gas. You’ll see both Zigbee models (mains-powered, plug-and-play) and WiFi 2.4GHz models on 230V, allowing you to receive alerts and—depending on the version—connect with your smart home app and voice platforms.

WiFi or Zigbee: what fits your setup?

Choosing between WiFi and Zigbee is mainly a choice about stability and integration. WiFi 2.4GHz is easy to set up (no extra hub required) and is commonly used for smoke/CO combo detectors and gas detectors. Zigbee is a great option if you already use a Zigbee hub and want to build a consistent, scalable network (for example with multiple sensors throughout your home).

Practical buying guide: what to check

• Detection type: smoke, CO, gas (LPG/natural gas), or a combo detector.
• Power: 9V battery, AA batteries, or 230V mains power (often convenient for gas detectors).
• Notifications: WiFi models often mention real-time alerts—useful for remote control and peace of mind.
• Sound & controls: for example a 95 dB alarm and a mute button for temporary silencing.

Complete your security setup

Smart detectors are strongest as part of a complete security approach. Combine them with Smart Security in general, add smart cameras to verify alerts with live video, or use smart alarm systems for extra deterrence and scenarios. Want extra context such as temperature/humidity? Then also check smart sensors.
