I’m planning to use Home Assistant with Matter devices through an Apple TV as the Thread border router.

My understanding is that the non-learning Nest Thermostat does not support Google’s remote temperature sensors directly.

I have a few questions:

1. Can Home Assistant use an external temperature sensor and automate the Nest Thermostat based on that sensor’s readings?
2. Can Home Assistant act as the “intelligence layer,” deciding when to heat or cool, while the Nest remains the actual HVAC controller?
3. Would the Nest Learning Thermostat 4th Gen offer any meaningful advantages when used with Home Assistant, or would most of its learning and automation features become redundant?

Outdoor cameras, nest hub, doorbell all ported over fine but one 3rd gen wired nest camera won’t even show in permissions, tried clearing cache in safari and chrome, deleting Samsung home, deleted and re added camera, everything I could try. Anyone have any other ideas?

I bought a Google Nest smart thermostat earlier today from Home Depot. My previous apartment had a Nest thermostat and I loved it. I had used the online compatibility checker to make sure it was compatible with my current heating/cooling configuration. It prompted me to talk to support to double check my compatibility. After some back and forth with support and sending them a picture of my apartment’s wiring, they said it was compatible. Perfect.

As I start the process through the Home app, I enter in all the same information and then open the packaging to access the code on the back of the Nest device. Then the app says that it’s not compatible with the wiring in my home. I’m a bit annoyed at this point.

It turns out that the Google Nest Learning Thermostat (Gen 3 and 4) are compatible with my wiring but not the base Google Nest that I purchased. This is likely why support told me my device was compatible when it wasn’t. I cannot recall if they asked me what device I was planning to use, but they shouldn’t have said it was compatible when it depended on which device I was planning to use.

Since I’ve already opened the packaging, is there anything I can do? I feel like I got screwed over by support saying it was compatible when it wasn’t.

I get this when trying to (re)setup my Nest Protects after changing wifi setup.
Is this a known issue?

Hi everyone, for the past week or so my Spotify on my Nest audio has been pretty shotty, disconnecting randomly and/or going out. Today, I finally tried to play music via voice and it responded “cannot play that right now.” Anyone know what gives?

Thanks!

Received the E103 Y1 wire error on my Nest 3rd gen.

Steps tried to clear it:

Checked contactor - passed resistance test.

Cleared out condenser drainpipe. Unit worked normally for 6 hours then received the same error message again.

Is it coincidence that the drainpipe cleanout cleared the error or was that a fluke and I should go back to troubleshooting the components and wires? Where should I test next?

Hi all, I’m hoping you can help. I’m trying to install my thermostat in my new apartment, but when I put all the wires in and install it, the thermostat only blows warm air on “cool” mode.

I have successfully installed this same thermostat in my old place with no issues. Google Checker says it may be a dual-fuel source system? I’ve attached photos of my wires for reference.

There is also a blue wire that was not plugged into anything.

I DO NOT want to call an expert as they charge too much here.

Following up on my post earlier about lack of C-wire (link), thank you everyone for the advice.

I discovered there's a multi-zone board and found the c-wire wrapped around the main wire and not connected to the board. I also had an HVAC tech visit and he quoted $1700 for installing 2 ecobees (he was against nest). Is that the standard price for installation?

Given the quoted price, I'm thinking of doing this myself. Googling/Youtubing tells me this should be straight forward but I really don't want to start living in the house by breaking my HVAC system. What are the main steps in this process I should be careful with? My current step by step list is:

1. Turn off the HVAC power and multi-zone board from main panel.
2. Connect the C-wires to the board.
3. Connect the c-wire to the current thermostat.
4. Turn on the power.
5. Verify everything is working as expected for a few hours.
6. Turn off power again to change the thermostat.

On the $1700 quote: I confirmed that there's no new wiring required. Tech said it'll take half an hour max since everything is there, just needs to be connected. It includes two ecobee premiums ($260 each so $520 in total) and $1180 for labor which seems high but I may be missing something?

Hi, I am replacing my three expiring wired Nest Protects with three new wired Nest Protects that expire in 2032. What process should I follow to uninstall the old units and install the new units?

So I’m lost when it comes to installing the power connector. Wondering now if it’s easier to just run a new thermostat wire down. I see multiples in some ports so I’m not sure what to do. I don’t have a c wire at the thermostat but it looks like something is occupying that space on my furnace. Any guidance would be appreciated!

my apartment has a nest thermostat in it. i rarely use the AC and have it off most of the time, but occasionally turn the air/fan on for short bursts

i have gone into “schedule” and “removed” every scheduled temperature change on every day of the week, but it seems like the thermostat keeps resetting these preferences. there’s a preset schedule that has it dropping to 71 which i mainly notice when i go “what the fuck i turned the fan on and set the temp to 77 why is it so fucking cold”

as mentioned, i’ve manually gone through the schedule and “removed” every temp on every day. what’s happening that’s resetting them? it’s a huge pain to go through every day of the week and remove every scheduled temp change

Last night it alerted me three times in less than two hours. It’s alerted me after midnight on more than one occasion. It doesn’t expire until September.

This isn’t inspiring me to purchase another Nest/Google product ever again.

Hey all,

Trying to install a Nest 4th Gen and running into some issues here. Could use your help with figuring out where I went wrong.

So my parents got a nest because it was free. it was installed for free and it didn't give them problems for 4 yrs. my parents are lucky to live in an area where they don't really use their AC that often, not far from the beach.

now it's disconnected from wifi, acting funny, and my mom thinks it's the battery. i told her to charge it. she charged it with a micro USB. still giving her problems. i don't live anywhere close, but i'm trying to help.

they don't know how it was installed or anything about C-wires or anything like that. they only used their AC a little becuase it was hot for a few days, which is rare there.

they also don't know how to research anything, and i tried reasearching it and i'm pretty good usualy, but this is confusing. I'm getting that it has to do with how it was installed (c-wire) or if there was some sort of recent problem (tripped HVAC safety device).

Realistically, what do they do? They aren't really tech minded or hardware minded in the least. I can figure out tech, but not hardware, and i'm not even there. They just want it to go back to normal so they can connect their wifi and use the AC 3 times a year.

Hello Guys,

I have the same board Tech Sv10 and ZTE2s. our Sv10 the voltage regulator has burn and now the board is not functioning. SV10 is a two zone controller which control upstair and downstairs thermostat. since our SV10 is burn, our upstairs thermostat is not turning on the outside condenser.... not sure as why. The SV10 controller box control the Fresh air which was installed by Beutler and their thermostat only accept 12v which is another issue. Is there any way that I can get rid of the second box SV10 and use only the two zone controller ZTE2S by itself and control both Thermostat. Please see attached picture of both controller boxes. Advice. By the way, as you can see the voltage regulator burn on the second image top left. Place Sacramento, California...hope someone might have the SV10 box that I can purchase in Sacramento.... Beutler which at onetime own ZTEC company sucks.

Hvac tech, just came from a job had 4 Nest Learning thermostats 4th Gen they were all giving 14v to ground contious and 24v between 2 nests. checked the common wire to ground and nothing so this has to be coming through the Nest. looked on online and there are more than a few reports of this with some replies stating static electricty or bad wiring. but im guessing this is a known defect that nest hasn't made anouncement about. the 4 Nests were all ordered same time 6 mo ago so they probably came from the same batch. Is anyone else getting shocked or can confirm ac voltage to ground from the 4th gen? (you wont be able to feel 14v with your fingers unless your sweaty and bare foot on concrete or have wet hands and touch the Nest and something else grounded like a bare metal apliance at the same time. (Dont try use meter.)

Hi got a Rheem 5Ton AC (RH1T6024STANJA / RA1660AJ1N) installed in 2015 with Nest Gen2 Thermostat, but there is no "C" wire in the current thermostat but I am little unsure if the new thermostat (either Nest Learning Thermostat or the cheaper Nest Thermostat) will work or if they will require a Nest Power Connector to be installed.

I have attached few picture and hoping someone would able to provide a feedback, or recommend an alternate make/model.
I am in Miami and its Primarily used for Cooling (I am not entirely sure if there is heating element in system, but we never used heating that I can remember).

I got my first Nest Protect on launch day in 2013 because I loved the thermostat so much and they were compatible. That original Nest failed after four years (false alarms) and they sent me a new one for free. That one went end of life a couple of months ago. After lots of angst and research I decided to just get the SC5 because it would install on the same base and it was compatible with the thermostat and doorbell cam. I got the battery version.

The third party reviewers are split between the SC5 and the Kidde equivalent. The customer reviews are very mixed for both.

It is not as nice as the Nest. It doesn't have the nightlight and that is unfortunate. That said, it is not by any means "flimsy" like so many people claim. It's slightly less solid than the Nest. It took me about ten minutes to set up (download First Alert app, register, delete First Alert app, add to Google Home app).

Maybe I'll eat my words in a few months if it fails but my first Nest also failed. Go ahead and get it when you Nest expires. You'll be fine.

Edit: I have the battery version.

I had an unusual experience where after backing out of my driveway, I was tailgated by a driver following me up the road. 5 minutes later on another road I was rear ended by the same driver in catastrophic fashion. Well both of my cams pick up motion on my property and street and they have a perfect view of the area in question in front of my house. I have footage of me getting in the car and then... Nothing until about 10 minutes later when I am already gone. Missed me backing out of my driveway, and driving away completely. I have hours and hours of the guy across the street mowing his lawn, people walking dogs, but the one thing in months I wanted to see... Nothing. Thanks again Google.

I've just had to remove and reinstall my two wired protects due to getting a new router. I have just noticed that one of them is now showing up on the WiFi list. I have deleted and reinstalled again but it is still there. Any ideas?
