Nest Protect P024 Error unable to reconnect more than 1 protect

jhferguson5 — Sun, 09 Mar 2025 17:08:55 GMT

In January my nest protects went offline. I can get only 1 (out of 4) to reconnect. I get a P024 error when I try to connect more than one. These have worked fine with my router and modem configuration for years. I've spent several hours online with google support and they told me after all that time this is a known software glitch with the app and firmware and they would be rolling out an update to fix it. The app updated today and the issue still exists.
I've gone through all the following troubleshooting steps multiple times:

reboot of modem and router.

reset all nest protects

reinstall app

restart phone

Make sure ipv6 is turned on

Make sure 5Ghz signal is turned off

connect directly to my modem WiFi

Nothing has worked. Has anyone heard if a real fix is on the way? I'm ready to trash everything google and nest and go with different products.

these used to work flawlessly until January.

Hi @jhferguson5,

Thanks for posting in the community forum. I'm sorry to hear you're having difficulties adding your Nest Protect to the app. I understand it can be frustrating that your service isn't working as expected, especially after troubleshooting it. No worries, I'm here to help.

Since you've already contacted our support team and tried some troubleshooting steps, which I appreciate, I won't recommend you repeat them. To investigate this further, could you please provide your case ID? This will allow me to access your support history and check the status of your case more efficiently.

Once you provide the case ID, please let me know and I'll be happy to look into this for you.

Cheers,

Unable to add second Nest Protect

gonzalezerick19 — Fri, 07 Mar 2025 01:46:48 GMT

I've had 8 Nest Protects working without any problems for years. I've changed wi-fi routers during that period and I have upgraded Nest Protect units numerous times, until now, have managed to move devices to the new wi-fi networks by removing and re-adding the devices to my account or simply keeping the same WiFi name.

I recently had one Protect fail as it was several years old and it needed to be replaced by 2025. When I tried to install the new device as usual, it failed. I created a new 3rd structure on the Nest app since all of my Nest Protect were already on a separate structure. I am able to add the device, but if I try to add a 2nd one it fails. I have reset Protect devices as a test, and I get the same behavior where only the first one connects.

I have a networking background and I 've tried dozens of times now for weeks following many tips online and reconfiguring my router. I replaced my old WiFi router with a new Orbi WiFi6 with 2 satellites which I kept the same name as before to avoid having to reconfigure all of my devices. Everything worked for months until I needed to add a new nest protect. Unfortunately, I no longer have my old WiFi router.

Is there a particular setting I will need to modify on the Orbi that will work as I think my last resort is to buy another WiFi router just for the Nest Protects since the Orbi does not allow to disable the 5Ghz. I can only lower the power to 25%. My old routers worked fine without IPv6, but the only difference was that they broadcast a separate WiFi SSID for 2.4Ghz. I get the same results even if I remove the 2 satellites from Orbi mesh network.

It doesn't matter which of the devices I add first - the first one is fine, and it always fails to connect to the assisting device when adding the second one.

Any ideas? Thank you.

Welcome to the club. There are many of us with this issue. Google seems to be of no help.

Yeah Google does not give a crap that their smoke detectors don't talk to eahc other after the most routine change that a home owner can make, change a wifi router

Does anyone have advice on a good competing product. Like many people on this community I am tired of getting the run around on why more than one Nest Protect can't connect to the Wifi Network. I would like to think if I ran a multi-billion dollar company I would equip my tech support people with the 10 most common Wifi routers currently in use and I would test my products and my app to make sure that the devices would work with the routers and provide some detailed instructions on how to fix it. Instead they act like its the first time anyone has had this problem and that it is clearly the fault of the ISP

I agree. Thank you. I will order a basic WiFi router just for the Nest protect. Hopefully that will do the trick. Google killed the Nest Cam IQ outdoor too.

I've started research and so far i've come up with the brand Ecobee. I'm looking for a smart thermostat and smoke/CO detector system that will communicate together. So far Ecobee is at the top of my list.

I made a second support attempt (after I made this post) and my case has been escalated to higher engineering support. My case # is 3-2005000038085.

Hi folks,

Thanks for reaching out.I'm sorry to hear you're having difficulties adding your Nest Protect to the app when you have one already added. Don't worry, let's work together to fix this. To help me with that, I have some questions:

Is your Nest Protect 1st or 2nd generation?
When you try to add another Nest Protect, are you getting any error codes or messages?
What is the color of the LED status light?
Are there devices or appliances (such as baby monitors, microwaves, cordless phones, etc.) near the device you want to pair?
Has the device been paired before?

Any additional details you can provide will be helpful.

Cheers,
Jonathan

"They will be working diligently to resolve it as soon as possible" -in my case they blamed the internet provider and said there was nothing they could do. Folks have been complaining for months now, so I think its blatantly untrue. The P024 error code does not even appear on the list of error codes that Google provides for Nest Protects. Here's the bottom line, your app no longer can communicate with any 2nd generation Nest Protect - it know when its connected but it can't do any Wifi changes. Folks only catch on to this when they buy a new Nest Protect, when they change their router or when their network name needs changing. Even if you have a seemingy working Protect you can't make it do a safety check from your phone app because it won't communicate. Gaslighting everyone that is is a problem with IPV6, internet providers etc. can't obscure the fact that your own product no longer talks to your own app.

This is a frequent and common issue. Google nest better get their act together and fix this issue otherwise I will look for an attorney who will take on a class action lawsuit. Google is raking in money for products which have become worthless to your users. Please pass this message up the management food chain. I am quite serious about this!

I haven't changed internet providers in 5 years, so I call BS on their little internet provider blame game. For me the issues started after they pushed out a firmware update. I found the PO24 error message buried deep within their support website and I'm not sure I could find it again easily. What I do know from scanning these boards is this is becoming a more frequent and common issue.

anyone know a lawyer who would take on a class action suit?

We wanted to add a 5th protect to our household and it would not add, kept getting P024 error message.

Support was absolutely no help, they kept blaming it on our WIFI. My husband and I both spent HOURS on chat with tech support and they never had a solution.

Our end result was they couldn't help, so we decided to plan our on strategy.

REMOVED all Protect's from the household, and reset to factory
We had to make a separate home for the protect - not with our Nest thermostat
Add the NEWEST protect first
When adding each of the next protects, newest to oldest, we had to activate both protects to help recognize, the PARENT one first, then the child.

FINALLY 8 hours of support time later they didn't help, we figured it out on our own.

SUPPORT WAS USELESS!! They go by a script and never really read your replies.

Error P009. One protect is added. The second 2 make it to the final adding to account stage and then errors out

Re: Unable to add second Nest Protect

MrMarvelus — Mon, 10 Mar 2025 22:03:23 GMT

So it works adding multiple without the thermostat? Will try this later. Wonder if everyone with the same issue also have the thermostat.

Re: Unable to add second Nest Protect

Oaktown1048 — Mon, 10 Mar 2025 22:04:31 GMT

The Nest thermostat is now in the google app, not the nest app, correct?

Re: Unable to add second Nest Protect

Oaktown1048 — Mon, 10 Mar 2025 22:16:27 GMT

One of 3 Protects is added to Nest App. The other two receive error P024 when trying to add them. I think mine are all gen 1. It's a small house so there are other smart devices and microwave nearby.

Re: Unable to add second Nest Protect

MrMarvelus — Tue, 11 Mar 2025 00:47:53 GMT

Well…tried creating a new home tonight and adding just the protects and had the same issue, can only add one.
