X-Sense WiFi Smoke & CO Detector Review: Two Sensors, One Reliable Alarm

The verdict

The X-Sense WiFi Smoke & CO Detector packs both a photoelectric smoke sensor and an electrochemical carbon monoxide sensor into one unit, appealing to buyers who want a single alarm covering both hazards instead of two separate devices. Reviewers consistently highlight straightforward installation, a clear LCD readout, and dependable performance, including praise for responsive warranty support when a unit failed. It has no Google Home, Alexa, HomeKit or SmartThings integration (Home Assistant only through a community integration) and no automatic self-test, so it suits buyers who mainly want reliable standalone (or app-connected) protection rather than a device woven into a broader smart home automation setup.

Best for
  • Homes with fireplaces or pellet/wood stoves
  • Buyers who want combined smoke and CO coverage
  • Basements and boiler rooms
  • Multi-unit household setups with a shared app
Buy on Amazon UK

Pros

  • Combined photoelectric smoke and electrochemical CO sensor
  • Easy-to-read LCD screen
  • Simple installation with included mounting hardware
  • Loud built-in siren and built-in light
  • Real-time WiFi phone alerts
  • Responsive warranty support reported by buyers
  • 5-year warranty

Cons

  • No official smart home integrations (no Alexa, Google Home, HomeKit, Matter)
  • No automatic self-testing
  • Larger than a standard single-purpose smoke alarm
  • Mounting bracket can be tricky to align perfectly level

Who is the X-Sense WiFi Smoke & CO Detector for?

This detector fits households that want one device covering both fire and carbon monoxide risk, rather than mounting separate alarms. Reviewers mention installing it near pellet stoves, fireplaces, and newly replaced heating systems specifically to cover the CO risk those appliances introduce, and several describe outfitting multiple rooms with the same connected system managed from one app. Its ceiling or wall mounting hardware and companion mounting bracket make it straightforward to add to an existing safety setup alongside mandatory smoke alarms.

What buyers love

The combined photoelectric smoke and electrochemical CO sensor is the headline feature buyers call out, appreciating covering two hazards from a single mounted unit rated for a long sensor lifespan. The LCD screen is repeatedly praised for being easy to read even without backlighting, and installation is described as simple with the included ceiling mount and screws. Buyers also value the loud built-in siren and built-in light, real-time WiFi alerts to a phone, and more than one reviewer specifically praised the warranty support, describing a fast, free replacement when a unit failed during the warranty period.

What to know before you buy

The detector has no official smart home platform integrations: no Google Home, Alexa, Apple HomeKit, Samsung SmartThings, or Matter, so it cannot be pulled into voice routines, and the only third-party route is a community Home Assistant integration that reads it from the X-Sense cloud account. There is no automatic self-test feature, so periodic manual testing is still needed. A few reviewers note the unit is noticeably larger than a standard single-purpose smoke alarm, which is worth accounting for when choosing a mounting spot, and the mounting bracket's screw holes have been described as awkward to align perfectly level without a reference line. As with any WiFi-connected alarm, actual wireless range in a real home with walls and obstacles will typically fall short of open-air marketing figures, so don't assume whole-house coverage from a single base without checking signal strength.

Is the X-Sense WiFi Smoke & CO Detector worth it?

With a 5-year warranty, dual-hazard sensing, and consistently strong buyer feedback on reliability and setup, this detector is a solid value pick for anyone wanting combined smoke and CO protection without buying two separate devices. It is best suited to buyers who prioritize dependable core detection and app alerts over deep smart home ecosystem integration.
