Review: Easy setup, loud alarm and discrete - Needing a smoke detector for the garage and wanting a smart alternative to a standard battery alarm i chose the Meross unit on ease of install, battery life and discreet looks. That it was Matter was a big advantage. I've had the unit for about a month now. The kit arrived well packaged with the Alarm, Matter hub MSH450 with UK wall plug and connecting cable. The alarm comes with 4x AA batteries already installed and a release tag which is removed before installation. Claimed battery life is 3 years. The Alarm is supplied with a backplate and adhesive pad and screws, I used the pad - recommend to not fit the alarm to the backplate immediately but allow overnight for the adhesive pad to do it's thing to avoid it falling off the celing after a month. Setting up the Matter hub was easy; flashing red/green LED on power-on, open the Meross App on my phone, hit the '+' icon to add the new device, scan the Matter 2D code on the hub and click through a few OK screens - all done in 2 mins. I could also have let my Samsung's SmartLife app do the process for me but chose not to. Testing the alarm from within the Meross App yielded an alarm from the detector plenty loud enough for my double garage. But the real alarm comes from the hub and it's piercing enough to have no concerns that it would wake the houshold and set the dog off in the middle of the night. Probably my immediate neighbours too. You can set up a weekly timed alarm check. The Matter hub can be used with other Meross devices like a thermometer/humidity sensor and water alrm, so useful for any future expansion. There's a short Ethernet cable included if you wanted a wired connection between hub and the house wifi router. All in all, I'm pleased with the alrm and have confidence it will do its job when needed. It looks great on the ceiling; low profile and discrete, and I'm tempted to buy another when the time comes to renew to house alarms. If I have a criticism it's that the alarm is fiddly to attach to the backplate whern it's above your head as it only fits in one orientation. Currently the alarm can be had for around thirty GBP which seems excellent value for the function it offers.
Review: Best product I bought of desertcart for a long time - Quick and easy, once the hub is connected, everything else just quickly goes online. Also fantastic value for money, imagine the hub itself is a good £19.99 and the alarm itself is £30.00. Looks decent quality and connected to my Apple home instantly without much fuss. And above all it’s a smoke alarm that detects CO and partly work as a burglar alarm. Woohoo!

## 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.

### ⭐⭐⭐⭐ Smart smoke alarm
*by C***D on 13 November 2025*

I bought this as an extra smoke alarm. Setup was simple (I actually already had a Meross hub setup) just pressed a button and it appeared in the app. Google home recognised it automatically after adding, just had to choose a room. The unit feels reasonable quality the plastic wasn’t too thin though the way you twist to attache to the back plate was a little fiddly. The alarm is loud so that’s good. It came with an adhesive pad which I used to secure to the ceiling.
