For some reason recently my nest has been throwing error codes. No power to Rh wire. I think i have a dedicated 24v common giving it power though.
Its only happened twice now. Once this past weekend and this evening while the dishwasher was running.
Some months ago my Chromecast with Google TV 4K died mid-OTA update. Rebooted and never came back. Now it boots to the Google TV logo and sits there forever. Tried the obvious stuff like hard resets, different cables, button combinations. Nothing. Put it in a drawer.
Recently I got annoyed enough to actually dig in. I'm not a developer, so I had no idea what I was doing but I was too stubborn to stop. What followed was several days across four computers and three operating systems, Windows ARM, Windows x64, and MacOS before finally remembering I had an old Linux laptop gathering dust somewhere. Things started making sense on Linux. And then got worse.
ADB/Fastboot: Device shows up as "GX-CHIP" meaning the hardware is alive, but standard Android tools can't communicate with it.
Amlogic USB Burning Tool: Actually detects it and shows "Connect success." But no compatible firmware image exists for this model in the format the tool needs.
Also fought driver issues on both the ARM laptop and the x64 workstation before giving up on Windows entirely
sabrina-unlock repair script: A community tool built specifically for this device. Runs fine on Linux, immediately hits: "Error: device is protected by password", a hardware password Google burned into the chip's eFuses via the February 2021 security update. It's physically etched into silicon. Not bypassable in software.
UART serial console: I soldered wires directly to test points on the board to read boot logs. Found the failed OTA corrupted the boot partition ramdisk. Also found Google disabled serial input entirely in their bootloader, you can watch the boot process, you just can't touch it. I even wrote a Python script to automate keypresses at the exact right millisecond to make sure it wasn't just human error.
USB hub boot: Bought a powered USB-C hub hoping to boot from a flash drive. Requires loading a custom bootloader first, which requires the exploit the eFuse password blocks. Circular dead end.
The hardware is completely fine, the chip, storage, WiFi, all of it alive and responding. The device is being killed by its own security architecture with no official recovery path.
The part that genuinely bothers me: the February 2021 "security update" that burned this password into the hardware is exactly what makes recovery impossible when a future update goes wrong. Google removed the community recovery tools and replaced them with nothing.
I'm in Argentina, bought through unofficial resellers so no warranty, but that's almost beside the point.
Did anyone actually solve this? Am I missing something obvious? Did I do a ton of dumb shit for nothing?
This is the current wiring situation for the machine. The issue is the building runs on a two pipe system and is currently set to cooling but my duct will only blow out hot air.
The super came in to check whether it is a compressor issue but everything is working correctly. The strainer for the compressor is not clogged either.
I am unable to check if the electrician has incorrectly wired this because the wire colours don’t match the colours shown in the nest install guide
EDIT - this is a 4th Gen model.
I've hated the Nest App Scheduler for years. It's unnecessarily difficult to select temperatures and times.
Does anyone else find this UI infuriating?
Out of all the unnecessary updates Google does (e.g. changing the logos of app icons) why can't they update this scheduler to be more user friendly.
Hi,
After freeing my nest thermostats with NoLongerEvil I didnt see any native apps alongside the web app and HA integrations.
In case anyone else was interested I published one here https://github.com/MikeSiekkinen/RestThermostat
I only have an android so wasn't able to test on iPhone but made an effort so it should build there.
Im certainly open to any feedback!
Is there a way to set a specific temperature on a nest thermostat when going to sleep, but have it go back into eco mode after an hour? I want to be comfortable falling asleep but dont need to maintain that temperature all night.
(Sort of how you can set a 30 min sleep timer on a fan or humidifier)
Why does my tstat e keep going to 75 and not stay on the temp that I left it at. I’ve turned off all the eco modes and even tried to lock it to the set point and nothing works
Hello,
We recently moved to a new home that has heat and AC controlled by a Honeywell thermostat . We want to fit a Nest thermostat.
I took the plate off the Honeywell and there are only two wires - a red R wire and a blue C wire.
Is it possible to fit a Nest to a two wire setup? We had a Nest at the old house and loved the simplicity of just turning the dial for temp selection. We miss it.
Thank you!
I have both Nest and Google Home installed, but unsure if anything is missing from Home nowadays?
Home has been fine for a while for me but with Protect in there now and schedules for Thermostat, I do wonder if I still need Nest installed?
I do get issues with presence awareness with my cameras indoors that are set to away only, they weirdly activate when my wife leaves the house and I'm still at home. Might help with that.
Is nest app down for anyone in Texas? I’m seeing the same page for 2 hours now.
It has been a very frustrating morning with Google and nest. We are no longer able to stream our nest cameras to our Google displays. I’ve spent over an hour with Google chat support and it’s going in circles. When I ask with my voice I am told it’s unavailable. This is the result when I ask in the app!
*edited to add*
LIVE camera viewing is not a paid service.
I have 2 Nest Learning thermostat. I think it’s version 3. They are both 6 years old. The one I have in the downstairs no longer connects to WiFi and loses charge. I’ve never had to charge it before. If I pull it out and charge it manually, it will connect for a little while and within a day says offline and a low battery again.
Could this be a Thermostat issue? Would the system stop charging the thermostat after 6 years?
I installed a nest thermostat yesterday in my new apartment and the AC is blowing but it’s not super cold and I can’t get the temperature down past 74. The honey well thermostat worked perfectly fine and it was very chilly in here
Any ideas ?
1st generation Nest Aware subscriptions ending
Curious if all or only some functionality has been migrated to the Google Home app, for the Nest Protect smoke detectors? These are my only Nest and Google products, so if I don’t need both apps, I’d love to get rid of one.
Moved into a house that has a bird-brained NEST thermostat. I have no idea which model it is. I want manual control, period. It does not seem to be set in eco mode, but it basically decides almost everything. If I change the temp setting it will say something like "until 11 pm" and after that time, it does whatever it wants to. If it is preprogrammed, I can find no way to deprogram it, in person, at the wall unit itself. We don't have an app, and will not install an app. Help?
Every year, since migrating to the Google Home subscription, I have gotten charged twice, once for the old Nest Aware subscription ($130/yr) and the Google Home subscription. Every year I have to contact Google support to get a refund on the Nest Aware subscription, and every year they assure me it is fixed for the following year. Well, fast forward to today and I just got charged for Nest Aware again. Has anyone with this issue had any luck? I am not able to log into the old Nest subscription login to cancel my subscription there, so I am completely unable to resolve this myself.
Hi All,
I have 2 old school Nest outdoor mains powered cams and an old school nest thermostat for central heating and hot water boiler. Not sure of generation but they're about 7 years or more old. I have a Nest subscription with that to get me I think 30 days of constant no gaps recording plus alerts.
I also have a newish Google cam indoors and battery outdoors one.
I keep getting migration requests from Google to migrate my Nest account as I have a paid Google account.
My concern is what I'd lose and what might break in the transfer?
Sorry if this is a dumb question. Nest thermostat came installed when we bought the house 6 years ago and I was already using nest cams at the old property.
What do you think my best strategy is as the Nest subscription is not cheap either.
Thank you
