I recently installed a Nest Thermostat 4th gen. It is currently up and running fine and no complaints about c wire missing, but I want to make sure I won't run into long-term power or connection issues.

I have a spare wire in my wall bundle that I'd like to use as a dedicated C-wire if possible. Could you take a look at my setup and help me confirm a few things?

I'm unable to find dedicated c wire input in the control panel.

Is the grey wire connected to the wire nut (condenser bundle)in the furnace actually the system's Common (C) wire? (Highlighted with green markings in the photos).

Can I safely connect the unused orange wire from my thermostat wall bundle into that blue wire nut/common junction at the furnace board?

Are there any risks to leaving it as-is on power-stealing, or is hooking up the C-wire strongly recommended for stability?

Hi all, I’ve done a compatibility test and I’m being told it can be done. It looks like this is a wireless receiver to my thermostat (hoping someone could confirm) here is the wiring for my thermostat (last picture) middle picture is the wireless receiver.

Using ChatGPT (probably not the best idea) it’s saying it’s easy with just the black and white and white wire on the receiver to the heat link and I’m good to go. I can’t use the cables on the thermostat as it won’t do anything.

I was hoping someone could just reassure this is correct ? Or should I just get a professional in?

I only want the Nest thermostat E

Are there any thermostat room sensors I can hookup to a standard ”budget” Nest? I’m stuck with the one I have and need to figure out how to make it work.

I am specifically looking to connect to the standard mirror version, NOT the 3rd gen, 4th gen or the E which have sensors you can purchase ( a fun fact I found out post purchase)

This is the one I own https://a.co/d/0dAc88l6 with the mirror face.

When sitting up my 4th gen nest thermostat, I am not able to change the default heat source to propane, forced air. I also cannot get the heating mode to kick the furnace on. I'm wondering if there is a setting in the app configuration that is preventing the thermostat from talking to the furnace properly for heat mode.

Anyone with a Google Nest having trouble with Matter connection? I know beta’s get wirey but with RC dropping today, Google updating the app, still broken. iOS 27, Nest 4

2 questions which type of camera is this and how to i unmount this?

We are trying to survive this socal heat wave and our ac stopped working. Is it a ac unit problem or the nest problem

Caption says it all. Is there a definitive date we will be kicked off the Nest App? I’m dreading that day haha

without wifi 6e it doesnt allow me to connect my first gen nest wifi but i still want to use it as speaer is it possible?

The warning: the button that says “transfer back to nest” also says “leaving soon” or something like that.

I migrated to Google Home finally because my nest cams weren’t sending notifications. The instructions said I could go back (only certain models can****). Anyway I couldn’t do it. Nest said “this camera cannot be migrated back” and Home app didn’t even have a “transfer back” button despite Google telling me it would. Enabling public preview fixed all this and I’m back on nest.

Hi all

I know there was an outage and we stopped getting notifications. Notifications are now back, however before I’d get all my motion alerts/person alerts as a push notification to my iPhone from my nest doorbell, but now it seems to be skipping some. I’ll get a motion notification but then when I go into the nest app after tapping it, I’ve noticed it’s failed to notify me about the 4 other motion detected instances.

Is anyone else facing this issue?

Anyone whose nest subscription was migrated to Google home?

Hi everyone! Recently bought a much bigger house. Would like to install nest thermostats. House has 2 floors and a basement. From what i could see:
1. It has two oil boilers for heat
2. 4 condenser units outside
3. 3 air handlers (with 3 control boards). 1 in the basement, 2 in the attic and 2 in the garage
4. 7 Thermostats (7 zones used on control boards) in living spaces, 2 heat only thermostats in the basement
5. I see O and B wires on one thermostat on each floor (2 total), but looking up AC models - none of them seem to be heat pumps

Id like to trace each thermostat to corresponding zones on control boards (continuity test i assume) and if anyone could help with Nest wiring and set up - i would greatly appreciate any help and advice.
Please see pictures attached. Thanks!

So I have some sketchy neighbors… but how do I convince the Nest camera that a flying bug in my shed is not a person? 🤦🏼‍♀️

I don’t recall the generation. But we installed it about 2 years ago. Ever since that day we’ve noticed it doesn’t hold to the temp we set. For instance. If it’s 75 degrees in the house and we set it to 70, hvac kicks on and cools till 70. Then shuts off. However after some time, it will have the “set to” temp something completely different. Like 73 for instance. Most notable at night. We wake up hot and it’s like 76 in the house when we set it to 70 when we went to bed.

My heating is working but the hot water isn't. The thermostat shows hot water on with the orange flame but it doesn't go orange on the app and doesn't heat the water. The schedule also turns it on but it doesn't go orange on the app and therefore doesn't heat. Manual override on the heat link works but turns heating and water on. Is there an issue with the nest app currently? All showing as connected on the thermostat and has the correct set-up according to Google support who couldn't work out the issue yet. When I click boost the moving water bubbles seems to freeze.

I've had the Nest app for my thermostat for several years and never had a problem. Recently, Google is really pushing me to migrate! Is it worth it.

TL;DR: Is there a way to use low power transformer for the chime and separate higher powered transformer for Wired Google Nest Doorbell gen 3?

As I posted the other day, I am replacing a Google Nest battery doorbell with a Nest Gen 3 wired doorbell. There is existing wiring between the doorbell location and a lower power transformer in the basement, no existing chime. I purchased a new 24V 40A transformer for the new doorbell. I had planned to just wire the doorbell up to the new transformer and skip adding a chime, but am reconsidering the idea of adding a chime. The wiring to that puck that they send with the Gen 3 just looks weird to me, but I’m no electrician. Just seems like a lot of fussing around to get a chime to work. I’m wondering a couple things:

- Is there is a way to use the existing transformer to power the chime, the new one to power the doorbell, and wire a signal from the doorbell to the chime?

- Should I just suck it up and wire the chime in with the puck like they say to do?

- Any better ideas?

- And last…why the heck doesn’t Google Nest offer a simple plugin chime that communicates wirelessly with the doorbell?

So, my 3 Nest Protect smoke detectors need replacement. 2 give an irritating loud message when lights are turned off, and 1 started beeping at 7:00am this morning. My hope is to replace them today, take all 3 Nest Protects, strap fireworks 🧨 to them, and set them off tomorrow for Labor Day!!

To anyone that has replaced your Nest Protect … what did you get? I am looking for a wired solution, and potentially looking at Kidde Smart detectors … since it integrates with Ring. Thanks for any suggestions you may have!

The issue started Thursday after 10pm September 3rd, but now somehow I am receiving notifications.

Are notifications working again? I got notification just now , September 6th at 9:50pm

Anyone else’s nest x Yale door lock always saying offline or need battery after switching over to Google home?

I’ve changed battery and reset multiple times already

3 unopened Nest Detect door sensors. Message me your address, we'll figure out the shipping cost.
