Review: Recommend - Meross is the best
Review: Compact and value for the money - Easy to setup. I also tested it in my bullet grill with a lot of smoke, it beeps lodly. This is the cheapest option if you have fireplace to detect carbon and fire at the same time. Too bad it does not connect to Meross app. It has sealed battery which should match the life of the sensor, 10 years. Quality of Meross devices is one of the top. It it very compact, perfect for low ceilings.

## Features

- 2-in-1 Function: The photoelectric smoke detector and electrochemical CO sensor work independently of each other. If the carbon-monoxide-detector detects both smoke and carbon monoxide, it sounds first for smoke and then for CO. The CO detector detects both fast and slow-burning fires, minimising false alarms.
- 10-Year Service Life: The smoke alarm and carbon monoxide detector contains one built-in 3V CR123A battery (not removable) that can last 10 years. You can avoid the trouble of replacing the battery, and it ensures your carbon monoxide alarm is always ready to protect.
- User-Friendly Design: The light and simple white round design ensures the carbon monoxide detector blends seamlessly into your home. The carbon monoxide and smoke detector includes a test/silence button (please press the test button monthly to confirm the working status of the smoke alarm). The fire alarm sound is over 85dB at 3 metres and sounds throughout your home; press the test button to silence.
- High-Tech: This carbon monoxide and smoke detector has an inbuilt smart chipset. The carbon monoxide alarm is automatically activated when it is attached to the bracket. The LED light is normally green and turns red in an emergency. The smoke alarm for home complies with EN 14604 and EN 50291 standards to ensure reliable quality.
- Easy Installation: The battery-operated smoke detector (not wired) can be installed by yourself in 5 minutes without the need for an electrician. The CO alarm is easy to mount on any wall or ceiling with the included screws. Note: Carbon monoxide is lighter than air, so it is recommended to install it at a distance of 30 cm from the ceiling.

### ⭐⭐⭐⭐ Not smart, but does its job
*by A***E on 1 April 2025*

Good luck slotting the alarm into the holder if you're mounting this on the ceiling! Its slimline design (very neat!) means it can be tricky placing the alarm into its holder. Too early to really give proper feedback, although I was hoping for this to be "smart" (as most things from meross tend to be). I haven't noticed the light that flashes regularly to indicate that the detector is working, which is good or bad depending on your take.
