It also pairs straight to 2.4GHz Wi-Fi with no base station, has a built-in light and shares the same five-year warranty. The X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts answers with a different job entirely: it senses carbon monoxide, temperature and humidity, speaks its alerts and shows an LCD with the CO peak, where the Wi-Fi Smoke Alarm detects smoke only. Neither integrates with Alexa, Google Home or HomeKit. Pick the X-Sense Wi-Fi Smoke Alarm for straightforward smoke protection, and the X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts for carbon monoxide with a climate readout.

What the differences mean

Which hazard it watches

The X-Sense Wi-Fi Smoke Alarm senses smoke only, with no CO sensor. The X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts senses carbon monoxide, temperature and humidity, with no smoke sensor. A complete home usually needs both, so this is a question of which one to buy first.

Battery life

The X-Sense Wi-Fi Smoke Alarm is rated for ten years on a CR123A battery, while the X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts runs about a year on the same cell type, so one asks for far fewer replacements.

Readout and alerts

The X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts has a backlit LCD and spoken alerts that announce the alarm and its location. The X-Sense Wi-Fi Smoke Alarm has no display, but it does include a built-in light that the CO unit lacks.

Connecting to the app

Both connect to the X-Sense app over 2.4GHz Wi-Fi, but the X-Sense Wi-Fi Smoke Alarm does it directly with no base station, while the X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts is also standalone and hub-free. Each is tested on its own.

What they share

Neither the X-Sense Wi-Fi Smoke Alarm nor the X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts supports Alexa, Google Home, Apple HomeKit, Samsung SmartThings or Matter, neither supports automations, and both carry a five-year warranty. The smart side is deliberately thin on both.

Which one to buy if

What owners say

Both X-Sense units have similar owners who wanted a connected alarm without a hub, and both describe setup in the app as quick. X-Sense Wi-Fi Smoke Alarm owners praise the real-time phone alerts, the solid build and the replaceable battery, and many use it in rentals or holiday lets where being warned from a distance is the point; they note it is smoke only, has no smart home integrations and no automatic self-test, with the app in English only for some. X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts owners praise the push notifications, the spoken alerts that name the room, and the bonus of a temperature and humidity readout. They flag the same closed-system limits and add that its in-app climate figures lag behind the live reading and that it cannot interconnect with other alarms.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.

Frequently Asked Questions

Which is better, the X-Sense Wi-Fi Smoke Alarm or the X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts?

They detect different hazards, so the right one depends on the room and the risk. The X-Sense Wi-Fi Smoke Alarm gives a decade of battery in a simple smoke alarm with phone alerts. The X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts is a dedicated CO alarm with voice alerts and a temperature and humidity display. A properly protected home generally wants both.

Does the X-Sense Wi-Fi Smoke Alarm detect carbon monoxide?

No. It is smoke-only, with no CO sensor and no CO alerts. Carbon monoxide is what the X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts senses, and it also reads temperature and humidity and warns by voice.

Do either of these alarms need a base station?

No. Both the X-Sense Wi-Fi Smoke Alarm and the X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts connect straight to 2.4GHz Wi-Fi and the X-Sense app, with no base station required. Each is a standalone alarm.

Which has the longer battery life?

The X-Sense Wi-Fi Smoke Alarm is rated for ten years on a replaceable CR123A battery, while the X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts is rated for about a year on the same battery type, with a low battery notification before it needs changing.

Do these work with Alexa or Google Home?

No. Neither the X-Sense Wi-Fi Smoke Alarm nor the X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts supports Alexa, Google Home, Apple HomeKit, Samsung SmartThings or Matter. Alerts and history live in the X-Sense app.

Who should buy the X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts?

Anyone with a gas boiler, stove, fireplace or attached garage who wants app-connected CO protection, spoken alerts and a temperature and humidity readout, without a base station, and who already has smoke alarms. For fire protection, the X-Sense Wi-Fi Smoke Alarm is the counterpart to buy.
