Meross GS559A Smart Smoke Alarm for Home with Hub, Battery WiFi Fire Alarm

Perfect for quelling my anxiety about leaving the cats at home whilst I’m out, loud alarm indoors and pings straight across to my phone, sleek fit and easy installation, connects straight to my HomeKit, excellent value for money!

UPDATE: 31-3-2024 After nearly a year I'm sincerely regretting choosing this alarm system. There have been far too many times when one or a few of the alarms have gone off without any reason, what's more I didn't get any notification on my phone. Once while we were away on holiday I was woken by the Meros app on my phone at 2am. Which incidentally is the only time the app has notified me of anything. Fortunately I also have some security cameras and was able to see there was no fire or smoke. Good job I didn't call the fire brigade otherwise they'd have smashed down a door to get in.All 8 of them are now going to come out and I shall try and find something else that actually works as intended. Whether or not I can get a refund remains to be seen. It's a shame as it would be a good system if it was reliable.I had been searching for a fire alarm system to replace my 13 year old interlinked system and eventually stumbled upon the Meross which met my requirements which were as follows.1. All alarms should sound if there is a fire. (Interlinked)2. If I was away from home I would get a notification telling me the house was on fire. After all, if there's no one there to hear the alarm no one will summon the fire brigade. The only downside is that if the phone is set to silent you won't hear any notifications and I haven't found any way round this yet. However, if the Government can have a warning App that overrides (I believe) the silent mode it must be possible.3. Replaceable batteries. There is no law stating that fire alarms have to be replaced after 10 years. So long as they are kept dust free there is no reason why they shouldn't last longer. It appears the reasoning behind 10 years is purely because the sensor could become inefficient due mainly to dust or a component could fail. Incidentally I have left my old interlinked system in place as it still works OK.4. When it detects smoke it is very loud, much louder than when in test mode. The pitch also varies which for me is very important as I have trouble hearing high pitch sounds and I can't even hear some alarms they are so high pitched.5. They are affordable so I didn't skimp and installed 8 fire alarms, ideally there should be one in each room. I covered every location that has, or could have electronic equipment, as that is the most likely source of any fire in our house.First I made the mistake of reading the manual and getting totally confused, except for the part about installing the App and following instructions. Hopefully this review will help you.The tiny matchbox sized hub is the part that communicates with all the smoke alarms and sends a notification to your router if there is a fire. I would advise locating it fairly centrally relative to all the smoke detectors. However initially plug it in near your router and pair it up with all the smoke alarms. During Setup it needs to be briefly connected to your phone in the same way you would connect your wireless router to your phone in Settings/WiFi. You select your WIFi's name and tell it your WIFi's password.I used an Android phone and Installed the Meross App.Open the App and on the home page click the + symbol in the top right.Scroll down until you see "Smart Sensor and Alarm" and tap that.You should now see the GS559A smoke alarm so tap that.NOTE: You use this for installing the hub AND the smoke alarm, read the text at the bottom of the page and tap that if you have already installed the Hub, otherwise tap Next.Just follow the instructions in the App to keep adding smoke alarms after you have installed the Hub.Should you need to re-set one of the smoke alarms there is a QR code in the manual that takes you to a video showing you. I re-set all mine as I set them up as you never know if someone else has linked it to a different Hub.Now you can fit all the fire alarms where needed and locate the hub to a suitable location.The downside to the system is that you won't get a notification if the power goes off and your Hub or Router stop working. Also, if the Hub stops working the alarms won't be interlinked.As our area often experiences power cuts and blips I have installed UPS devices on the router and in my office for the computer. Unfortunately I don't yet have the Hub plugged into a UPS, it's a shame that there isn't a battery backup in the Hub for such emergencies, as in my opinion electrical items are the most likely source of fire and when they go wrong they could also throw the main trip for the property.The main purpose of a fire alarm is to save lives, saving your property is a bonus. I'm impressed with this system as it allows both.The App allows you to test the alarms directly, no need to run around pressing buttons. You can also see the state of the battery for each alarm installed and get low battery alerts. You can turn on/off alerts for Smoke, High temperature, Device malfunction, Low battery but they should all be on unless you have a good reason to turn one off. Which could be installing one in the kitchen, in which case you would perhaps turn off Smoke as most kitchen alarms are heat sensitive. That's something I hadn't realised when I bought the system so I'll get another for the kitchen.The location name for each alarm can also be changed in the App. It's a good idea to write the proposed location on the back of each alarm as you set them up, otherwise you could have 8 on the table and not know which one goes where. I used a Dymo label printer for that.I hope this review was helpful.

Got two of these at the same time and they were quickly and easily integrated them into the Apple HomeKit ecosystem. Installation is a breeze (they’re battery operated, not mains powered, so you can place them wherever you like). They’re quite small and blend into the ceiling (assuming your ceilings are white). You will need a Meross hub to provide connectivity, but will happily work in standalone mode. When they’re triggered the alarms are plenty noisy enough. However, the real bonus (if you’ve got the hub and connected them to HomeKit) is your iPhone, Apple Watch, etc. all light up like a Christmas tree and start sounding their own alarm (so if you’re away from home, you can tell if it’s burning down remotely). Pretty cool. There’s a neat self-test feature which you can activate from the app to give you peace of mind. For some reason, only one of my alarms responds to the self-test, so 4 stars.

Really good and connects up to Apple homekit

Easy and simple to set up. you will need to buy one at least with the home hub dongle but once you have it you can add more smoke alarms with no issues at all.Adding them all in to Apple HomeKit was a breeze and sit quietly in the metros hub section.They do not have Carbon monoxide detection in these like other smart smoke alarms but these are less than half the price and offer the same protection for just smoke as you would expect from smart features.I have these in an outbuilding also as this is also covered by Wifi so a good added bonus if smoke is detected we now get the notice on our smart devices also and could save a building if something happens.

Setup was easy enough but it randomly goes off for no particular reason every few months. Also, don't vape around it as that'll set it off.

False alarms all the time, useless, no longer panic when they go off, which is not good.... I bought 10 of these, so in too deep to return by the time I found out they were rubbish. They all false alarm, day and night.

I am really pleased with this purchase as it gives me a live account on my mobile through Bluetooth. I enjoy the Meross products as part of the ecosystem created through their app: the weather station combined with the temperature and humidity sensors are very useful for monitoring each room and keep my house safe and healthy.Meross is a reliable company where staff respond promptly to your emails in person when you have a query. If a product has a defect as it can happen with technology sometimes, I received a replacement promptly once the issue is explained.Altogether a reliable smoke alarm that keeps your mind at rest; this is why I chose Meross.

Fonctionne parfaitement. J’espère qu’il ne sonnera jamais, sinon ce serait la catastrophe vu qu’il y aurait le feu.
