Our nest protect smoke detectors are expiring soon. Since they are no longer being made, what is recommended to replace them with? What works with the nest system?

Google partnered with First Alert, and the new First Alert Smart Smoke & Carbon Monoxide Alarm will be available in the US and Canada soon and interconnects with existing Nest Protect devices.

Hi David, can you be specific on the model for replacing my hardwired Nest Smoke & Carbon Monoxide Alarm? I am so confused on which one is replacing the nest that we currently have.
05-28-2025 02:08 AM
First Alert Smart Smoke & CO Alarm will be available in hardwired or battery powered options in the coming months through US and Canadian retailers, on the Google Store and FirstAlert.com.

By “connect” do you mean it will fit in place of expired Protect units? (As and when)
06-18-2025 07:45 AM
As stated by David K, First Alert has the replacement detectors your looking for. I ordered mine a while ago and it's should be at my house today. there was a delay in getting due to manufacturing issues, but it seems that it's fixed. Google Store will direct you to First Alert since Google no longer makes the Nest devices.

Unfortunately the Google store directs you to a site that only ships to a small foreign market.
If I put my postcode in for delivery, First Protect do not ship here.
Time to look for an alternative from a company that ships throughout the world rather than to a small minority.

Thank you! We did find them online and placed an order for a couple of them. Hopefully here soon!
06-18-2025 11:51 AM
Where did you order from? Do they ship outside of Trumptopia?
06-18-2025 12:03 PM
Not sure exactly what you mean by Trumptopia, the US? I'm not sure if they ship outside the US. I think we just ordered from the first alert website, but I'll double check

What about in the UK?

You're out of luck it seems. Very poor from Google product, def puts me off entering that ecosystem. I remember when nest was nest, and the skies were blue...

Yes. Same happening with my thermostat. V poor. I'd expect more from google.

Thank you, that's very helpful!

Finding these new First Alert devices on their website can be hard since they have not been released yet. I am being told they will release to pre-orders around June 12th, 2025.

One new feature of the wired version is that it has a third wire, allowing you to connect it to regular smoke detectors.
Here are the direct links to the wired and battery versions.

Thank you so much! Ours are all set to expire between July and March, so hopefully they're out soon

Is it not utterly infuriating that a completely working and fine device will have to be replaced because Google bought the company to what? run them down?
This means that apparently I have to replace devices that cost £100 each. Those devices have been completely rock solid, never let me down, always notifying, self testing and reporting home on a regular basis.
So apart from the loss of £400, there's the waste of materials and the effect that has on the environment... nothing made to last?
When I get products like this, many of my acquaintances will laugh and say why not buy a normal £5 smoke alarm. I've had them, when you remember to test they don't switch off, or you find they are not actually working, or batteries ran out. They don't tell you what's happing, give you directions, and send messages to your phone.
On the other hand, I think they might have been totally right now. Very disappointed.
So I can evaluate the options, does anyone know of a good product to replace them?
In the EU, from any ecosystem at all.

To be fair, all smoke detectors expire eventually. Mine will be 10yrs old over the next 6 months, so they're due to be replaced anyway.
06-03-2025 01:56 PM
They are still supporting them, but only to their expiration date, which all smoke detectors have.
These are Life Safety Devices, and First Response is a much better fit in my book. I will miss the Nest Protects.

I think the other issue for UK users is unavailability of First Alert in the UK. I accepted replacing unit after 10 years and not just batteries after 5. When we designed the apartment we fit the Protect plates flush and thought replacement would just be with same which fits into the plate. Really annoyed.
06-06-2025 04:11 PM
I understand your frustration, but manufacturers of all types are known for discontinuing products that impact users all the time. My business deals with this all the time, and it really hurts when it costs thousands of dollars for the device.
06-07-2025 10:45 AM
I think that's different. I have a 15 year old computer that's working fine. Not made any more, but it's fine. I have a 20 year old TV that's not made anymore, that also works fine...
Being told that the device has to be swapped out because it's been discontinued is not a normal practice.
06-07-2025 08:24 PM
Here in the United States, it is required by law, as the sensors used have a set lifespan.
You don't need to replace a Nest Protect until its expiration date. Google Nest just isn't going to be making new ones.
06-18-2025 11:55 AM
Except mine have not expired, and I am being told I have to replace them now, as they won't work anymore - not supported.
So I am without protection until I splash the cash - again...
06-18-2025 06:58 PM
No, you do not have to replace them now. They will be supported until they expire, and you can buy new ones until stock is depleted.
06-19-2025 02:51 AM
The reason I reached out was that I get emails saying my nest cannot connect anymore.
I then talked directly to support, twice, who both said they are no longer supported and I have to replace.
That means the alarm still works, however things like remote monitoring and mobile alerts do not work - which is one of the key benefits of these types of systems.
So yes, they do need replacing now.
06-11-2025 04:32 PM
This is the big issue.
Google/Nest have retired a product with no comparable replacement being sold - the only link on the support site is to a company who only markets their products in a small (closed) market and I could see no way to put a domestic address in - they seem to only ship to the Disunited States.

So there's no update on this.
Firstly, outside the US one cannot replace devices that genuinely go past their "use date".
Secondly, those that are within use date have to be replaced as well.
This is not only extremely disappointing, but also bad customer service and business.
For anyone interested, after a long chat with support, I was able to get a refund on my nest protects.
I urge anyone else in this situation to do the same.

Update: we ordered a First Alert detector and installed it replacing our first expiring nest detector. It was easy and quick to install. You have to download yet another app, but it works with Google home.
