Excellent, easy to install and operate via the wifi setting. Best thing about it is being sent a fire alarm warning to your mobile and being able to switch of the siren remotely when accidentally activated via your mobile. You can see the battery life wifi signal etc on the app . Worth every penny and peace of mind!
Having built up a collection of electrical woodworking tools and a lot of timber as well, I decided a WiFi connected fire alarm was sensible.
Very easy to connect up with my mobile phone. It tested out well with the alarm in the workshop going off and a similar sounding warning coming on my phone.

What I like about this time does the job perfect so far I have no complaints. I have tested it multiple times and gives a nice play Sound letting me know that there is a smoke around.
Non mi hanno dato una buona impressione.
Funciona correctamente
Manufactured by dahua, n. 1 in security cameras.
This WiFi smoke alarm from Wisualarm is the perfect way to keep your home safe from fires. It's easy to install and use, and it provides real-time alerts to your smartphone if smoke is detected.
The alarm is also certified by T?V and complies with the EN 14604 standard, so you can be sure that it's reliable and meets the highest safety standards.
I love that this alarm has a replaceable battery. It means that I don't have to worry about the alarm losing power and becoming ineffective.
I also like that the alarm is compatible with the Wisualarm Home Security app. This allows me to receive alerts on my smartphone if smoke is detected, even if I'm not at home.
Overall, I highly recommend this WiFi smoke alarm from Wisualarm. It's a great way to keep your home safe from fires.
I love how improvements in technology allow things such as this to be made. Where instead of just the traditional fire alarm, you can now connect it to your phone via an app.
I've tested it out by lighting a cigarette next to the alarm and it not only goes off like a traditional smoke alarm, but the notification was sent straight to my phone, alerting me in real time.
I hope I never have to use this alarm and take advantage of these modern features, but if I do, from what I've seen from testing it so far, I think I'm in decent hands.
The WiFi Smoke Alarm with Replaceable Battery is a reliable and convenient option for home safety. Its compatibility with the Wisualarm Home Security App allows for easy monitoring and control from your smartphone. The T?V certification and compliance with EN 14604 ensure its quality and effectiveness. With its replaceable battery, you can trust that this smoke detector will provide long-lasting protection for your home. Overall, this 1-pack smoke alarm is a great investment for your peace of mind. We have fitted ours in the landing so far so good.
Having at least one smoke alarm in your home is essential for everyone's protection and this product has the added benefit of an app that works with it.
The app was easy enough to find and install, However, I did have to make a couple of attempts to get it to link to the detector, but it did it in the end. So if you have problems, persevere as it will link at some point.
There are some good benefits to having the app. It tells you the status of your alarm, whether on-line or off, whether it has a fault and the status of the battery ( which is replaceable). If your alarm goes off, it alerts you even if you are away from home.
Like everyone, I hope that never happens.
The alarm has a test button and that is very loud.
It all works perfectly as I found out when I burnt some toast the other day and I got an alert very quickly on my phone, although the screaming alarm was notification enough on that particular occasion.
I really like this product and although you can get cheaper smoke detectors I like that it works with an app for that extra peace of mind.
Great fire alarm , easy to install and has app to simply set up and activate as well as do tests .

This was easy to install overall, however, the best feature is the online tracker and the fact that god forbid you can see from away if the alarm was set off, and at ?25 at the time of this review it costs same as a normal one so I would advise you to consider this for your home.
It's okay and looks okay, not actually had any fires yes to make sure if certainly works but that's a good thing.
Good idea for fire safety
Great alarm which alows you to be alerted of a fire even if your not home.
Brilliant.
Very easy to install. The base plate can be screwed to the roof or using the supplied sticky pad stuck onto the roof. I opted for the sticky pad which worked well. The alarm paired easily with the app and onto wifi and the app gives notifications if the alarm is trigged. Easy to use, good quality and good value. Very happy with this.
This seems to be a decent smoke alarm but it is around twice the size as 1 I have in another room but still not as big as a standard smoke alarm, It can be fixed via screw mounting or as I did with the included sticky pad , The instructions aren't bad but could be better , After I managed to pair it up by the following day for some reason it showed offline and I couldn't get it back online so I deleted it and added it again and it seems to have been fine since, The app is quite good with a few settings and notifying you of a test or action performed.
Decent small smoke alarm. Fitted to my home office ceiling in seconds via the supplied em sticky pad.
Look good, works well (tried with an extinguished match) and hopefully will never be needed.
Not sure I'll even bother with the app, it's there is you want it.
This smoke alarm came properly packaged and with all instructions. The instruction is easy to follow and I had no issues connecting this alarm to the app. The initial test worked and the alarm is now installed on the wall. I am planning to buy more to install all around the house and connect all together.
Highly recommended!
Thank you for reading my review. I hope that you found it helpful.
Replaced a faulty smoke alarm with this.
It was easy to install and the template for drilling and screwing into the ceiling was really helpful. Especially if you are a DIY newbie.
My only criticism was the app was a bit fiddly to set-up and timed out a couple of times.
I had been looking to replace the smoke alarm in my house, as my existing one is around 15 years old already. With the proliferation of SMART devices, I also found this SMART smoke alarm.
The app was quick to install and alarm is easy to setup via the app. The app has some useful features such as battery level indicator, alarm notification via app, alarm status (online or offline) etc. one of best feature which I loved is to be able to stop the alarm (in case it goes off when you are cooking).
You can also share the app with 18 users which means your family can also get notifications in case of smoke alarm going off.
The batteries can be replaced easily.
Please note that the alarm only works on 2.4 GHz band (which is quite standard for many SMART devices), but please make sure that you select the right WiFi SSID if your router supports both 2.4 and 5Ghz bands.
Overall a good smoke alarm.
Hope you find this review helpful.
Its a wifi smoke alarm. Easy to use and set up. Sturdy and durable. Can be connected to app which is pretty easy to use. You can see the device details on your phone also the battery level. Perfect for kitchen or anywhere in your house. Will recommend.
Working so far
This Smoke alarm is a really nice idea. In the box is the alarm, Template sticker, adhesive pad and screws.
Once you have positioned it where you need, pull the tab on the battery and the alarm emits a bleep.
Using the supplied QR code, you scan it and access the software allowing you to connect wirelessly to the alarm. Although limited, the software allows you to silence the alarm, useful for when it goes off during cooking etc but also monitor battery status and alarm status remotely.
Very easy to use and install, good addition to a standard smoke alarm.
Small and neat looking WiFi smoke alarm, simple to set up as the instructions tell you, scan QR code get the wisualarm app, create an account. Once you have the app you can then add devices, again scan the QR code on the alarm and add you router password and or finds the alarm. I had a problem after this a few times were it came up faulty on the app as you can see in the picture, I deleted the alarm and had to add the device and delete a couple of times and then it sorted it's self and all ok. The app tells you the alarm is online or off, your battery percentage and the device status. It has a test/silence button on the alarm and this also sends you a message to your phone. I have not tested the alarm with smoke but have in test mode and all works ok. The alarm looks neat on the ceiling and it's nice to know if it was to go off you will get a message on your phone were ever you are. You get a template to mark the holes to fix the alarm along with the Rawl plugs and screws, or a double sided sticker to use.
This smoke alarm is an amazing value for money.
I have used it in my log house at the back of the garden, we have a log burner and before we go to bed, we do make sure fire is out, however still always feel slightly anxious.
It was so easy to install it, and the app is so simple! Anyone can do it. Nothing too complicated.
Hopefully i will never have to hear it or get any notifications, however its ectra peace of mind.
Also seems to be well built.
Highly recommend, and the price is just great!
This is a WiFi enabled smoke alarm which I real like as it has the ability to notify me of an alarm where ever I am as long as l have my phone with me.
It works just as you would expect and has a loud siren and also has a replaceable battery. The WiFi feature require you to download the app which is on app store or Google play and it's just a matter of following the on screen prompts and instructions. The only thing to be aware of is it only connects to 2.4ghz band.
I can recommend it.
This smoke alarm is small but very loud. The set up was very easy and took me less then a minute to do. Very easy. The alarm comes with 2 fitting options 1) a sticky pad which sticks the base plate to wherever your sticking it to or 2) screws to fix the base plate in place.
When you remove the tab it will emit a loud beed but after that the rest of the set up is a small quiet beep which shouldn't alarm anyone. When you look at the app and under device status- it says fault make sure it's connected to the bracket this should get rid of this message and it should read device status normal
The alarm is 3.5cm in height and approx 9cm wide so not to big
To keep everyone safe looks arnt important and knowing I can get a alert when I'm not home is added peace of mind.
