My 1st gen thermostat just random started making the clicking noise it would make when someone interacts with it. It will intermittently sound.

Has anyone had this happen before?

Battery is fine, network is fine, just randomly started doing it.

I was just about to go to bed when I suddenly heard a chirp and got a notification stating one of our Nest Protects (1 of 3) has low battery. Not sure if others will chirp tomorrow or in some point in the near future.

The Nest Protects were manufactured on January 16, 2022

I installed these on March 2, 2022. I had path light enabled on all 3 units (default setting), but I lowered the brightness on them.

I had to replace the batteries on all 3 (got notified on January 22, 2023 that all 3 had low battery). I replaced each units batteries on January 25, 2023.

Only thing that I thought was causing the battery drain was our dogs walking underneath the Nest Protects and activating the path light. So, I ended up disabling it.

Fast forward to now (February 3, 2025), just got notified that 1 of 3 units has a low battery... 😐

Only other setting I can think of is disabling nightly promise or perhaps the heads-up setting (mainly burnt food in kitchen).

I thought these were supposed to have batteries that could last at least 5 years before having to replace them. I'm using the recommended Energizer Ultimate Lithium AA (L91) batteries (which are already pricey as is).

Edit: The one that needs battery replacement is our second floor unit. 1st floor (kitchen - main culprit in smoke alarms) and basement unit haven't reported low battery.

We just bought a new house with an oil heating system. I want to get a next to help control the system so we can save some $$$ but I literally have no idea where to start when it comes to finding out if my system will be compatible with Nest. Looking to get the new gen 4.

Any help is much appreciated! Thanks!

Whenever someone comes and presses the doorbell and I see a notification and open the app, it takes forever to load and kinda just freezes there and I lose the live view, which kinda defeats the purpose of seeing whos there.

And then after they leave I guess I can view a replay. There's usually a 5 second clip of them coming, and then there's a 2 minute video of the rest i guess. That 5 second clip is fine, but the 2 minute video never loads. Anyone else have this problem?

Our "Cool" setting on our Google Nest was blowing hot air permanently earlier this autumn, so we just kept Heat on 72.

My friend got hot today and decided to put the Cool setting on.

The condensor outside, and unit (idk what to call it) in the closet starts clicking. Now when we keep it at Heat 72 it just keeps clicking.

I took the Google Nest off the wall and the clicking stops.

How can we get it back operational, Heat set on 72, without the clicking? Thanks.

My google nest protect falsely went off without any heads up warning, and when I got an alert on my phone, I immediately knew something was wrong and went to that area and looked, it was just steam from the shower and that's it (the alarm was installed in the upstairs hallway). Does anyone know why this happened?

I purchased a used 1st gen indoor nest cam as I really liked the other one i purchased 4 years ago. I used the Nest app to complete setup and had no issues during setup except that the status light doesn’t turn on. In the Nest app, it says that the camera is offline. I called Google who advised me to restart my modem and unplug the camera, that didn’t work. They had no other troubleshooting to offer and suggested I replace the device. Any tips to get this camera to work or is it a lost cause?

I recently moved and the house came with Nest Doorbells which appear to be the battery version, but the owner hardwired (looks like ~24v from my meter check). When I started them up they were only at 2% battery. After 30 minutes they are at 1% battery. Is there anything I need to do to get them to charge via the hardwired wiring?

Hi all! I have a Nest thermostat with a heat pump and furnace, I saw on the thermostat sometime that the aux heat is on, but the furnace don’t start but when I put manually the emergency heat, it’s working! I don’t understand why because the aux heat and emergency are the same wire…maybe something in the setting?

Thank you

What exactly are the new features of Gen 4 vs Gen 3? I googled but it’s not very clear.

Is there an outside temp sensor available now or is it still temperature data?

Is there more support for dual fuel like time of use?

I have three nest thermostats. Hooked to a two wire boiler system. I have never had any issues with charging until the last month or two. I have three zones. Living room. Master bedroom. Nursery. Living room is set at 70 constantly. Nursery 70 constantly. Master bedroom is turned off constantly. Lately the nursery has been going dead after roughly two weeks. The other two thermostats are working fine with no problems as the nursery was until this recent time. I know they’re designed for a 3 wire system but I have enough power through the lines to keep them charged and like I said haven’t had a problem since install about a year and a half ago. Is it possible the internal battery needs replaced. Tonight I am going to put the one from the master bedroom in the nursery to see how it lasts over the next week or two and see if I get the same results.

Location- SE FL

I live on the 8th floor unit condo. The AC unit is located in the hallways closet next to our condo here. When my AC turns on it rumbles and it’s definitely noticeable. Recently I was looking at settings and turned Airwave and boom the sound went away.

What happened?

Abito in un condominio con caldaia condominiale pompa di calore e ho notato che impostando su off il termostato ambiente, i termosifoni continuano ad essere tiepidi .. la casa rimarrà vuota per un po di tempo ... la domanda era ... i contacalore attaccati ai termosifoni continuano a funzionare ed aggravare sulla bolletta oppure essendo su off si spengono e smettono di conteggiare ? Grazie per chi mi risponderà.

Im in another country and not able to troubleshoot this directly, so im trying to fix this temperature issue for my wife. If it gets any colder she'll have to find somewhere else to stay with our newborn.

Nest Learning Thermostat 3rd Gen ran out of battery despite being plugged into the wall. When my wife charged it and put it back, it only blew cold air. No C wire but never had this problem for 2 years.

Furnace is gas and Google Home App shows gas and forced air under settings.

I've attached the wire diagram. Any help is appreciated!

I have 10 nest third gen thermostats for controlling my ac’s for the last 18 months or so

Five of them no longer connect to wifi. Four of those still function manually. One of them reads the temperature 10 degrees too high so is always wants to come on.

I reset it but and the temperature error dropped to 3 degrees. Can’t see anyway to offset, anyone know how?

The problematic thermostats all say low battery even though they are wired in. Is there anyway to hard shut then down so they can recharge internal battery? Or any other fix?

I got the vendor to replace two earlier on but it was difficult as didn’t retain original packaging which was apparently required so since then I’ve just been living with these things. Getting to the point where I may just have to find another thermostat.

We have 2 wired nest doorbells. Last week they both started to show offline at the exact same time. We have restarted the router, and tried to reconfigure the WiFi but when we tried to connect to the camera to do that, it won’t connect.

It’s almost like it’s not getting power? I can’t even get them to restart using the button on the back.

Any ideas to troubleshoot??

I have a full nest aware subscription for my home with plenty of storage. My SIL needs a couple of cameras at her aging mother's house. Can I set up her mother's few cameras as a different house (same state about 200 miles away) under my account and let her share my subscription? I assume I would have to family group her, which is not an issue, but then she could have the alerts and I'd have the back up video if necessary? TIA for opinions

We have a nest E thermostat.

We connect to the WiFi, then it randomly disconnects. Can’t connect to app because of M15 error.

If factory reset twice. What am i missing?

Just realized nest changed my schedule without letting me know. Showing a yellow leaf and said it will save my cost during the season. Come on, don’t be over smart to do anything like this. Do you really think that lowering the temperature by 1 degree would make much difference? I need something predictable and don’t play such boring game with me.

Hi

I think I got the 3rd gen and have my whole home humidifier setup, but I am so confused in the app if the toggle means it is on or off?

Does this toggle turn on my humidifier, or does it just mean that it will keep it 35% or more? If toggle the switch, will my humidifier be off?
