Wired doorbell says "offline due to extreme temps" but it's 60 degrees. Was there a software update?

[Texas1234]

Yesterday, my Nest Wired Doorbell (which I integrated to the Home app from Nest a long time ago) started saying it's "offline due to extreme temperatures." 

This can't be the case as it's over 50 degrees outside. I've flipped the breaker several times and can get it to come back on for about 2 minutes before it goes off again. Anyone know a fix? I'm assuming it's a bug with an update. This is very bad timing as it is porch pirate season.

It's actually a first generation, not a 2nd

That is bizarre. We have never received an "extreme temperatures" warning on any of our 1st gen Google Nest cameras and doorbells, but we also have not "transferred" them from the Google Nest app to the Google Home app. (We live in Minnesota, where we DO get cold temperatures; it's 1 degree Fahrenheit right now, and all are online.)

[Texas1234]

Right?! My wired doorbell cam is 8 years old and I'm wondering if the internal battery is no longer charging and that's just the default message in the Home app? I migrated it back to Nest and it just says offline. I've confirmed it's not an electrical issue on our end.

I don't think the problem is the internal battery. That is a known issue affecting many hundreds of customers.

The internal battery has now failed on all three of our Nest Hellos.  (They are 5, 5, and 4 years old.) That causes them to go offline for a minute whenever the doorbell button is pressed because that diverts power from the doorbell to the doorbell chime for an instant, and the internal battery is supposed to keep the doorbell (and its camera) online for that instant.

We have turned off the "Indoor chime" on all three doorbells to keep them from going offline when the doorbell button is pressed. We rely instead on "Visitor announcements" on our Nest Hubs.

Maybe, since your doorbell is older, something else is going on, and due to defects in the Google Home app, its triggering an incorrect error message.

Hello @Texas1234,

Thank you for reaching out to the community. I understand how concerning it is to see an "offline due to extreme temperatures" error on your Nest Wired Doorbell when the weather is a mild 60 degrees—especially during "porch pirate season." I apologize for the stress this is causing; it is certainly unexpected for the device to report temperature issues in such moderate conditions.

According to our guidelines, a wired doorbell should operate between 4°F and 104°F (-20°C and 40°C). At 60°F, you are well within the safe range. However, two common factors are likely at play:

• Internal Battery Degradation: Even "wired" doorbells have a small internal battery to bridge power when the chime rings. If this battery is failing, it can cause the device to overheat internally or suffer voltage drops that the Google Home app incorrectly reports as an "extreme temperature" event.
• Migration Sensitivity: The Google Home app often provides specific error reasons (like temperature) for "offline" events that the older Nest app would have simply ignored or labeled as a generic connection drop.

If you have a silicone cover or "skin" on the doorbell, please remove it. These can trap internal heat and cause the sensors to trip even in 60-degree weather.

Perform a Full Factory Reset

A clean reset can sometimes clear a "stuck" sensor state.

• Remove the doorbell from the wall mount.
• Hold down the reset pinhole button on the back and the main doorbell button on the front simultaneously for 15–20 seconds.
• The light ring will spin, and you'll hear a chime. Re-add it to the app as a new device.

If the error persists immediately after a factory reset with the chime disabled, it unfortunately points to a hardware failure of the internal temperature sensor.

Regards,

Kevin

12/21/25 - had the very same thing happen this evening...very mild outside but 2nd gen doorbell offline due to excessive temp message. Unplugged several times for a few minutes...starts up then goes offline a few minutes later. I deleted it from Home app...will try the factory reset advice and reinstall on home app in the morning...

Did that work?  Following

Mine is a 2nd gen Nest Wired Doorbell been working fine for years until I migrated to Google Home last year was fine still. Then last month added Gemini for Home and then been getting every few days the offline because of extreme temperature issue. Power cycling the breaker brings it back. I'm on the Google Home premium subscription   in Pittsburgh PA and temps been around 32 to 40 degrees F when it's happened

Your reply does not address what customers are reporting; namely that, after "transferring" their 1st gen Google Nest Hello Doorbells from the Google Nest app to the Google Home app, the doorbells are suddenly offline and the Google Home app is falsely reporting that this is due to "extreme temperatures".

This certainly seems like a bug in the Google Home app that affects "transferred" 1st gen Google Nest Hello Doorbells. We have three 1st gen Google Nest Hello Doorbells, and I do not want to "transfer" any of them from the Google Nest app to the Google Home app until this bug is fixed.

Same has happened to ours after migrating to Google Home app from NEST.  In the UK so its not freezing weather.

Wired Gen 1

[Texas1234]

I will update you all on our status. I tried to reset it multiple times after removing it from the mount and accessing the back. We totally removed the gen 1 and I brought it inside and tried the USB plug on the back for battery only power and couldn't get it to work. I migrated to the Google home app from Nest when it was first optioned so that wasn't a recent change for me. 

I got the new wired gen 3 so we are back online. It was very annoying to have to pay for a new one at Christmas but I will say it's an upgraded camera with a wider field of vision. 

Again, I will note we did not have an electrical issue. We tested the wires. 

Best of luck to everyone. I hope you don't have to upgrade but if you do, you will like the new doorbell camera. I got the linen color.

Thanks.   Annoying, I had a £50 off voucher last week for being a pixel superfan and gave it away!!   

Will keep an eye out in the sales.

Just ordered a gen 3 from Amazon the beige one was $40 off at $140 plus added the 3 rd extended warranty for $23. Since nest doorbell only has a 1 year factory warranty.  You saved me the time to remove my Gen 2 wired doorbell and hit the reset button and try again. Right now it's tripping off every 24 hours with the offline due to extreme temperature error

[ElJefe-Earl]

And for Gen 2 wired doorbells once you transfer to Google Home you cannot transfer back to the Nest app

@ElJefe-Earl 

The 2nd gen Google Nest Wired Doorbells are only installed in the Google Home app and have been available since late 2022.  Do you actually have a 1st gen Google Nest Hello Doorbell?  (We have 3.)

(Google Nest's product naming standards are hard to follow.)

[ElJefe-Earl]

You right must be a 1st gen wired doorbell   because I bought a cover for it in 2019 on Amazon

I transferred my front doorbell over to the home app. Boom, it gave me the same message "Device offline because of temperature" 40F outside. I am an electrician with mad computer skills. I checked the voltage, the router, wireless signal strength and channel. Could not chance it so I ordered a new one. Then I started hitting the forums. WE CANNOT GO BACK TO NEST! I am all in on google home devices BUT if you aren't going to fix a known problem then maybe I am backing the wrong horse. I have a T-stat, smoke & hall light, outside cameras, inside cameras. I will give you one month to address this. By address it, I mean FIX it. I will be telling family and friends not to transfer over to the home app.
