Nest Smoke + Co2 Alarm

False alarming and google after sales service feels like a third world 2 bit operation – I have purchased these as replacements for my old smoke detectors and I have had d 2 separate false alarming issues, one stopped after a full reset but the second did not stop, the support process from google almost seems deliberately difficult. for a company the size off google it is not acceptable, many failed attempts before I was able to even… Read more

organise the replacement and the process to send it back is shocking. After searching the items, it seems they have readability issues and google appear to make it very difficult to sort out a resolution

Reliable and Smart Home Safety: My 5-Year Experience with Google Nest Wired and Battery Smoke Alarms – I've been using both the Google Nest Wired and Battery Smoke Alarms for the last 4-5 years, and I couldn't be happier with their performance. These devices are perfect for remote monitoring, giving me peace of mind whether I'm at home or away. I would personally recommend opting for the hardwired unit, as it comes with the added benefit of a… Read more

Pathlight feature, which is essentially a night light that turns on based on motion. It's a small but convenient touch that adds to the overall experience. The battery unit also has this feature, but be prepared to go through batteries more frequently.

Yes, these devices are smart units, so a bit of tech know-how is required for configuration, but once set up, they work seamlessly. Overall, these are reliable, well-designed smoke alarms that offer great value and functionality. Highly recommended!

Worth getting but very frustrating – These are probably the best smoke alarms you can get in terms of features and detection capabilities. However, they are annoying. The self test feature is good on paper, but it consistently goes off even when people at home, despite advertising that it waits until everyone is out of the house. Not good when someone is napping, in a meeting, or a… Read more

baby is sleeping.

Their support is terrible. They're extremely hard to contact and not helpful at all.

Two died on me – First unit died within 2 years so was able to get a replacement for free. 2nd one died 2 years and 9 months later. Too bad they don't last, don't think I will try another one.

Nest Smoke Gen 2 a Dud - Very Disappointing – I had a Gen 1 unit for 10 years, it then announced that it had reached the end of its life and needed to be replaced. I bought the replacement in January 2021 and it was easily installed (battery operated). I already had the app and it detected the new unit straight away. I was disturbed that the unit was old stock having been manufactured in Oct… Read more

2019. Within a week it announced that the batteries were low and required replacement. I did so assuming the unit was 'old'. Within a month the unit again announced that the batteries required replacement. I bought the most expensive Energiser batteries however, this week (April 2021), the unit chirped again that the batteries were down. I looked online and found several mentions of this fault. Google suggested ensuring that the firmware was current and to buy Energiser batteries - both of which I've done. I'm now going to attempt to apply for a refund although there doesn't appear to be a local Google presence.

Check manufacture date – First, the units are well made with terrific features; however take note of the manufacture date. Reason, the unit has a running life of ten years from date of manufacture NOT date of installation. I had purchased two units from seperate locations in January 2021 and on opening found the manufacture date on each unit as October 2019. Units are… Read more

already 15 months old before I walked out the store.. Retailers locally have old stock and getting older and still charging full price for on this ageing stock. I purchased with the expectation of at least ten years use and challenged one of the two retailers I purchased from who agreed and to their credit gave me a satisfying part credit.

The extra cost is - possibly - worth it for the extra features – (Note that the device is a smoke and CO ie carbon monoxide not Co2 ie carbon dioxide detector - carbon monoxide is the nasty one you don't want to breathe, whilst carbon dioxide is relatively harmless to breathe although is not so great for global warming) It was ten years since our house was built, so it was time to replace the smoke detectors.… Read more

Yes, they are recommended to be replaced every ten years. I bought one of these to try it out, and liked it so much I replaced the rest of them as well. The hard wired ones need to be installed by an electrician, but it's a simple job for them to do. The only thing they need to be aware of is that the power cable coming from the unit needs to be double insulated - but that's easy enough for them to do. The battery versions of course can be installed by anyone, but if you are replacing existing hard wired units then the hard wired ones are what you should use.

Operationally they are set and forget. Why do I think they are worth the premium? Well, physically they are well made - definitely a quality bit of kit. The old detectors these replaced looked nasty in comparison. More than that though, they talk to each other - so if one goes off it lets the others know so, for example, if you are upstairs the detector near you will let you know that smoke has been detected in the kitchen. If the power goes out during a fire, not only do they operate from their built in batteries, they can still talk to each other *even if the wifi goes out* as they use the wifi plus their own internal network (called "Weave" that uses both wifi 802.11 and 802.15.4) to communicate. They also do a regular self check (by making a test noise at a time you choose, and an inbuilt microphone checks to make sure they work) - you are supposed to do this yourself but I never did with the old ones and doubt most people do. They check not just for smoke but also CO (Carbon Monoxide), which is particularly important if you have gas appliances like a fireplace. They can operate as night lights (they call it "Pathlight") that automatically go on/off when they detect movement - also good to help you find the exit if there's a fire. If the alarm goes off, not only can you silence them by physically pressing the button on the detector, you can use the app - so no hunting for broom handles or step ladders.

What don't I like? Well the fact that you need to rely on your electrician to properly double insulate the power connection on installation is perplexing. It is lazy that Nest haven't done this to meet local regulations, but it is amazing that they don't do that by default - double insulation reduces the risk of a power short that could in turn lead to a fire. Pretty ironic if a smoke detector *caused* a fire. The only other minor annoyance is that Google bought Nest in 2014, but six years down the track and any form of integration with Google Home is yet to come - it would be nice, for example, if when motion is detected by the Nest Protect you could have other lights turn on. Or imagine if there is a fire detected, it could automatically turn on ALL the lights, send alerts out on any smart speakers, and unlock the doors. Now *that* would make this not just a nice to have, but a must have.

Anyhow, although I personally feel it's worth the extra cost if replacing old detectors or installing new, and they do go on special every now and then - making them less expensive - for the moment I cannot say *you* should install these. If you don't need CO monitoring then they are just a nice to have, even if you are a geek like me. If they finally get the integration sorted, then I'd shift this to a must have for anyone with a home automation system.

Fantastic system – Bought in Feb 2018 from Ebay. I initially bought this brand because our builder had a standard smoke detector installed just six feet from the stove top. The rotten thing went off every time I cooked and the kids got tired of having to stand guard with the tea towel. I bought two of the wired-in versions of the Nest from Ebay.com.au and paid… Read more ·  1

approx $200 each. I then spent another $200 getting an electrician to install them. They are great. They actually talk to you, well a robotic voice does anyway. It will tell you if there is smoke or carbon monoxide and it will tell you if you need to leave the house or call the fire brigade. It also tells you which room it is detecting the problem in because you name them when you set up the phone app. The best part about these alarms is that you can silence them. The one in the kitchen is still six feet from the stove top but when the voice tells me "There is smoke in the kitchen." and I know it is just me cooking something and there is no real danger, I can reach over and hit the silence button on my phone and keep on cooking. It will also silence the one in the hallway. Then it sends a push notification to your phone, where ever you are. Once a month it will go through its own checks and balances to ensure it is working properly. Apparently if you buy their cameras too, it can automatically record video of any smoke or fire and send it to your phone. The other good feature is that they act as a night light when they sense you near and turn off after you've moved away.. I highly recommend Nest.

Well worth the high price – I first purchased the Nest detector some years ago when you couldn't get 240v versions. Opting for the battered versions. Nest products are extremely well made. Their functions are far superior than alternatives. They have designed a contemporary and functional detector. They are beautifully packaged and look impressive. They even come in black. I… Read more

recently purchased a 240v hardwired version from iselect who supplied the 2017 Block house's. I was very disappointed with the iselect delivery service. Taking far longer than stated. I had to chase and chase to find out the status of my order. I would highly recommend Nest products but would seek out other suppliers

Best I have every installed or used – Why do I think these are great, When you have a house with more than one alarm and there is one going off and trying to figure out which one, if there is no smoke. Its hard. This will speech to you. Smoke detected in Loungeroom, Co2 detected in Hallway. Then tells you what to do for the silly ones. Has a light you can program to… Read more

come on when you walk down the hallway.

Wifi connected so no interwiring needed for two level houses to connect.

Connects to your phone to let you know if alarms and even if there is no power at home.

Checks itself all the time, warns you of battery gettting flat and also when needs to be replaced.

Yes ALL smoke alarms have a lifespan. usually 10 years to chuck and install another, remember that when you install one, this will tell you.

Overseas will shut down your heating if CO2 detected but I think Australia is a long way behind this working, we normally are 5 - 10 years behind the USA and EU.
