X-Sense XC04-WX Wi-Fi Carbon Monoxide Detector

Protect your home (house, apartment, rental property) from invisible carbon monoxide with the smart X-Sense XC04-WX detector. Thanks to its Wi-Fi connectivity, it instantly notifies you on your smartphone in case of danger, even when you are away.

Key advantages:

2.4 GHz Wi-Fi connectivity: connects directly to your home network without a hub, and to the “X-Sense Home Security” app for real-time push notifications (CO alarm, low battery, malfunction).
LCD screen displaying CO concentration (approx. 30 to 999 ppm) and memory of the highest recorded value.
Powerful audible alarm ≥ 85 dB at 3 m — loud enough to be heard throughout the room.
High-reliability electrochemical sensor with up to 10-year lifespan.
Replaceable CR123A battery with approx. 1-year autonomy under normal use.
Tri-color LED indicators (green = normal, yellow = fault/low battery, red = alarm) for easy visual monitoring.
Flexible installation: can be placed on a flat surface or wall-mounted using the included screws and plugs.

Why this model is an excellent choice:

Smartphone alerts keep you informed even remotely — ideal for rentals, holiday homes, or extra peace of mind.
Large display lets you see CO levels, not just hear an alarm — useful for attentive users.
Connected + long-lasting design combines modern safety with low maintenance.
Trusted manufacturer in home safety products, reinforcing reliability.

Important notes:

Only compatible with 2.4 GHz Wi-Fi networks; 5 GHz is not supported.
This is a carbon monoxide (CO) detector only — it does not replace a smoke alarm. Installing a separate smoke detector is recommended.
Even with smart features, proper installation (temperature range, placement, etc.) is essential for optimal detection.
Since the battery is replaceable, plan to change it when needed during the device’s lifespan (~10 years).

Installation tips:

Mount on a wall at an appropriate height, often near combustion appliances or in a hallway.
Avoid very humid or dusty locations.
Connect it immediately to your network and name each detector by room in the app for easier identification.
Test the device after installation using the “Test/Silence” button and occasionally through the app.
