    Product Overview

    Enjoy complete peace of mind at home with the Nest Protect smart alarm. It’s a smoke and carbon monoxide detector in one, so you can rest assured that all fumes will be monitored. This alarm can detect varying levels of smoke, so when you’ve burnt the toast you’ll get a calm voice alert instead of the full siren. It sends notifications directly to your phone, and you can turn it off remotely too – no more towel wafting required! It automatically tests its own batteries and sensors, and its 10 year lifespan means you’re protected for the long term. Plus, it has an integrated light with motion sensor, so it’ll gently illuminate your path at night when you need a glass of water.

    This model needs hard-wiring into your home, so you may need the help of a qualified electrician to install it. It also includes 3 Lithium AA batteries as a backup in case of a power outage.

    Features we love


    Through their line of smart products, Nest create a home that takes care of the people inside it. Their products are designed to talk not only to each other, but with other smart home products too, all coming together in the Nest app to give you a single point in which to manage everything. So by starting with a Nest, and adding more devices as you go, you can ensure your house tailors itself to you.

    Find your way in the dark

    It’s not just emergencies where this smart alarm is useful. There’s a built-in light that will activate if and when you walk underneath it. So if nature should happen to call during the night, the pathlight will softly illuminate your route to the bathroom.

    Works with Amazon Alexa

    This product is compatible with Amazon Alexa, providing you have an existing Alexa-enabled speaker. Just open the Alexa app on your smartphone or tablet and you’ll be able to connect this product. Then, you’ll be able to control it with just the power of your voice.

    Intelligently identifies the type of fire

    Get advanced warning of any emergencies thanks to the alarm’s ability to differentiate between different types of smoke. The Split-Spectrum sensor contained within the alarm analyses the particles in the air, and by doing so can detect both fast burning and smouldering fires faster than more traditional set-ups. As a result, you can rest assured that when called upon, the alarm will activate early ensuring you can get to safety.

    No more wailing

    Whilst most alarms will just sound a siren, this smart alarm talks to you. If you’ve got several alarms around the house, the friendly human voice will tell you which room the smoke is coming from. It will also let you know when its detected smoke coming from the kitchen before sounding the alarm, so you won’t need to start wafting the tea towel if you’ve just burnt your toast.

    Extra connectivity for extra safety

    This alarm is compatible with your Philips Hue products and Nest Thermostat for an even more intelligent home set-up. By synchronising these smart devices, they can provide added safety in an emergency. If the alarm goes off, your lights come on, illuminating your path, and your thermostat will turn off the heating to keep any danger from spreading.

    Works with smart speakers for voice control

    This product is compatible with selected smart speakers for even greater control. Once you’ve synchronised your device with your speaker, you’ll be able to turn it on and off or adjust the settings with a simple voice command. So you can get comfy, and let your virtual assistant do all the work.

    Adding extra units was easy

    2 new Nest protect units came to join an existing one. Setup was straight forward. You might want to consider taking a picture of the QR code and information on device before installing it on the ceiling. Note: Nest Protect can only join 2.4GHz WiFi network. Many years after setting up our first unit, Nest Protect is still the best product in its category.

    Pricey but worth it in my opinion

    These things are expensive when you compare them to a regular wired alarm, but they are good, and what price do you put on safety. Some of the features might seem a little gimmicky on first glance, but with young kids they are actually quite useful. Night lights to show the exits for instance, and voiced warnings before an alarm telling you of where the problem is, rather than all alarms going off and giving you no idea why or what’s happened. Also, with most other systems you can’t mix battery and wired alarms, so unless you get every location spot on when first installing cables, you can’t add any additional rooms at a later date, but with these all you need is either mains power, or batteries as they don’t require a signal cable between every alarm like others. They also perform their own periodic test so if you struggle to remember to do this yourself, you get a little chirp every now and then to tell you and a report in an app. Happy days.

    Easy to set for a HUGE piece of mind to protect the family

    Pretty easy to install on the existing wiring. The set up of the alarms is really simple just like all other Nest devices. I bought two of these to replace the existing devices that seem to be programmed to annoyingly 'pip' in the middle of the night, which these are guaranteed not to do. The Nest devices so far haven't had any false alarms due to steam from showers, which the old devices were sensitive to, I've tested them for this specifically. The night light function is really useful too.

    Good smart alarms

    Good product all around. It is easy to install and set up, I had the wired version and was able to get the three set up in about half an hr. The nest app interface it's ok but I was expecting a bit more interaction with it. But it is ok as you can set up different functions for the night light. The real plus of those smoke alarms is the pre warning functionality, they do not start screaming but warn you of the possible alarm being triggered, ideal for false alarms where you have the time to silence it. Pricey but overall a good item!
