[@mostlychris]

If you are having issues with the credentials are having errors related to already existing Nest credentials in Home Assistant, take a look here: www.mostlychris.com/nest-integration-with-home-assistant/ There is a quick note about how to delete your old credentials so the new ones can be used.

[@Zosu22]

From what it says on the integration guide in HA does that mean this will break come October 2022?

Ooops after tree try’s miss worker, i read this comment. Please integrate a short notice in your video. Would be great! Thanx for the help! 💪🏻💪🏻

I'm new to home assistant and trying to figure out how to make all my different devices connect and work together. This video took care of every issue my Nest was giving me and I'm able to use it perfectly with HA now. It's people like you who are knowledgeable and helpful that help these projects spread and grow the community. Thank you so much!

[@johndekoven7549]

I almost gave up on Nest and Home Assistant. I figured I would check the project one more time and voila! And on my birthday no less! This is awesome and working thank you!!!

[@mostlychris]

Thank you so much for the support and glad you got it working! Shout out to Allen Porter for getting it all working.

[@jmckenna2k10]

OMFG. I kept screwing up on the Device Access ID and was entering OATH ID. I's been nearly a year and I finally have this working, thanks to your video clearly pointing me at the right locations for project ID and device access ID

[@jamescihacek3426]

After having tried it several times with other videos and now having no hair left I stumbled upon your video. Thank you so much for this tutorial. I was able to get it working thanks to you.

Excellent! Good job!

[@brianself4593]

This is hands down the best tutorial on how to accomplish this. Thank you so much Chris!

[@guillermo.didonato]

Hi Chris, thank you very much for this greatly detailed guide! I followed it step by step and got the Google Nest Thermostat finally integrated to Home Assistant. Thanks!

[@dagrainger]

New to Home Assistant and getting to know the environment. Followed your video on setting up the integration for Google Nest to get my thermostat into HA, and of course it worked flawlessly. You do a great job of walking through this process and explaining what steps are needed and in what order. The fact you also point out some "gotchas" is great as well so we do not make mistakes. Great job, and your work is appreciated!

[@mostlychris]

Welcome to the rabbit hole! Glad you got it working. This is probably one of the most complex of the integrations in HA.

[@miguelavello7493]

Hello Chris, thanks so much. Very nice step by step tutorial. It worked PERFECT. I appreciate your efforts and the patience to have this video completed in a such professional way. I am follower and will keep an eye on your videos. Awesome job. ~Miguel

[@mostlychris]

Thanks Miguel! Kudos to Allen Porter for building the integration.

[@michtheset]

I had a few problems at the start but your video cleared everything up. my thermostat and camera are working. Thank you

[@RealWizardry]

Absolutely fantastic! I got my thermostat added. Awesome. Thank you!🤩

[@paulrain5743]

Congratulations on your guide! Complete newbie here and following your guide I have my nest equipment integrated first time. Many thanks

[@wstrater]

Thanks for updating the video. I was less than successful the last time. A couple of takeaways that might help others. Basically what I had before was correctly configured except the Desktop versus Web Application. Once I deleted those credentials I also needed to update the Device. You are really configuring two distinct Google products. The first part was setting up access to Google API. The second part was linking Nest to your Google project. Not sure if others didn't find that very clear. I also have more than one Home Assistant running and the redirect after authentication went to the other one. I just updated the URL in the browser location bar and got a blank page. When I went to the browser tab with Home Assistant it was ready to continue. Thanks again.

[@mostlychris]

Thanks for the pointers. I think I mentioned the linking but it might not have been clear. In the my.homeassistant.... you have to specify the correct location for the device you are integrating with. I originally had it pointing to Pi but changed to my Blue so I could run the integration.

[@wstrater]

@@mostlychris Others may have found it clear but since I was trying to fix a previous setup instead of recreating it as you had suggested, I was jumping around and trying to understand what I was doing. So often when I am just following steps, I don’t understand the big picture and struggle if something doesn’t work.

[@coletraintechgames2932]

HOLY Frig'N Shoot! IT WORKED!!! I cant tell you how many of these type of vids I have watched and half way through, got lost, or the process had changed, etc, and just had to give up, this one worked! Overall, had to note my excitement, and wanted to shre some heartbreaks along the way, for laughs or etc. - 10:39 - (due to my paranoia, trying to meticulously follow along) We dont actually see you hit "submit" it just jumps to the next screen and after multiple rewinds and fast forwards, I can see a wisp of a "creating" in the bottom right that gave me the confidence to move forward - 16:18 - LOL I was gaining confidence and had already pasted the WRONG ID in there, and thought, I'll just wait to double check what he says! LOL Thank goodness, thank you so much for clarifying which one we were pasting! THANK YOU - 17:50 - Mine errored! OMG NO! I was able to go to integrations and get going again. I was so panicked that after all this "I had blown it" (like I said inititally) Thank you so much for such a detail oriented Video! Liked / Subscribed and did a little dance too!

[@rarriagaj]

Amazing stuff! If you do everything that is demonstrated here then you are SOLID!

This was an excellent step by step tutorial, especially for someone who's never leveraged this before. Thank you!

[@mostlychris]

You're very welcome!

[@blakebowden955]

@@mostlychris Going through your videos (hopefully I find it soon) - do you have one on how to create a custom card, from beginning to end? I've read the documentation multiple times, and i believe i'm missing a step somewhere in the process because i receive the error "custom element not found" thanks in advance!

[@mostlychris]

If you are getting that error, either you haven't installed the custom element you are trying to use or you have a cached version of the frontend that will require you to clear your cache in your browser. The easiest thing to do is search HACS for the custom card you are trying to use and install it. If you don't have HACS installed, I have a back to the beginners series that has a section on installing and using HACS. You can also look through my Dashboard playlist that has some custom card stuff in it.

[@orandaadnaro]

It took me two or three tries but your tutorial has got my Nest Thermostat back inside Home Assistant. Thank you very much 🙂

[@mostlychris]

Outstanding! Glad you got it working!

[@fredericesnault5373]

Man thank you so much. I was not able to integrate Nest (following the documentation from HA to the letter). I don't know what changed but I followed your video, and when you said "Delete your device management app if you have issues" I did it and recreated it. That's the only thing I changed, and voilà ! Also it's important to be connected with the same email adress between Google and HA, but you said it too. People, this is a perfect guide, follow it step by step and it should work.

[@SticksTheJon]

Thank you. It all felt immensely complicated, imagine my surprise when it actually worked!

[@cristiandorbesi1027]

Nice update. I was following your prior guide yesterday to integrate my Nest Hub Max. I finally manage to make it work with your video and the official documentation when I found about the changes. Nice that you made the update! By the way. Still cannot see the camera from that hub :(

[@antoniodecrisci2369]

Me too! Cannot see the camera streaming from my hub max. The logs have an authentication error. :(

[@mostlychris]

Check the troubleshooting page for the Nest integration to make sure there aren't any outstanding issues with cameras.

[@justinamrhein5573]

Thank you, thank you, thank you! You made it so easy to follow, I really appreciate it. I was able to get my cams setup and working in HA. I will say though, having gone through all these steps to get it integrated in HA, which was one of the most intense integrations I've personally had to setup. Plus having to pay $5, which is a first for any integration. I'm very underwhelmed with what I can do with my Nest Hello and Nest IQ cameras. From my experience, the live stream is several seconds behind what I can see in the Google Home/Nest Apps. Also, the integration for the cameras have no switch to toggle the cameras on/off. The integration just says "Streaming" all the time regardless if it's actually streaming or not. There's also no exposed sensors so I can't even setup motion based automations from the cameras; literally all the integration does is give you a live (delayed) feed and that's it. Anyone else experience then same? At OP, these negatives are at all no way shape or form a negative towards you. Your video walkthrough was absolutely fantastic. Just frustrating to feel constantly let down by Google. Please keep up the excellent content! Thanks for what you do.

[@mostlychris]

Thank you Justin. We are of course ath the mercy of what Google will expose. I'm still waiting on the Nest Protects, if that ever happens. At least we can access what is exposed now and not have the auth problems.

[@malcc2278]

Thank you for such a comprehensive and well explained guide. I was struggling with this for hours before finding your guide. The Google side is so complicated!

[@jakemoore3008]

You've earned my sub with this one! I was ripping my hair out a month ago trying to get my Nest cams into HA and just finding little scraps of info that folks had used to get it working. The most viable solution at the time was to have to re-auth every 7 days and that just didn't gel with me. Thank you so much for this follow up video! I look forward to the next one when Google breaks it again. T-T

[@mostlychris]

Thanks for the sub! Glad you got it working. Here's hoping Googs leaves it alone for awhile. If I have to do this again, it might just be time to change thermos. I've had these Nests for 8 or more years now I think.

[@AGR96]

May I ask if you had to do any extra steps to have the cams show up in HA? I have an IQoutdoor cam and a thermostat, but only the latter showed up in HA after going through these steps

[@metadera]

Had one which started no to work with several problems . I couldn't reuse anything whatsoever . Did it all over and now it works again! thx

Followed your last tutorial you posted that got me up and working with the disclaimer. Followed this new tutorial to immediate success with no headaches. Thanks so much. These videos have been absolutely crucial to me getting my Home Assistant to the next level. It would have been nice to provide a shortcut abridged text version of what changed for the integration so that maybe we could cut over.

[@mostlychris]

Thanks for the feedback and glad you were able to get it working. My blog might be a future location for the abridged version.

[@qwarlock4126]

For anyone getting "Can't link" errors - you *must* delete your old Application Credentials first! I've wasted hours because of this. 1. Go to "Devices & Services" 2. Click the 3 dots in the top right 3. Click "Application Credentials" 4. Select your old credentials, then click "Remove Selected" @mostlychris would be great if you could add this step or just pin a comment. Thanks for this excellent video!

[@ricketyca]

[@THEmallorywoods]

Great video. I had followed your older video right before the process changed. Make sure you follow this exactly and if the first menu to store creds doesn't pop up your old creds are saved and it won't work. Make sure you delete them! Thanks again for the great video

[@mostlychris]

That is a great point. It won't ask again for the creds if they are already stored. After the fact I thought about having that in the video.

[@bigbirddk]

THANK YOU !! I had it running about 6 months ago, then removed the configuration from my configuration.yaml, and I was not aware that it would still save those crendentials. For others: The applications are stored in the top right corner of the integration menu, the 3 dots. There was my old and no longer working credentials.

[@mostlychris]

I added a note to my blog and a pinned comment linking to the blog. App credentials are hitting a lot of people.

Great video, worked a treat (Eventually after I removed old Nest credentials). FYI, Not sure if you are aware, but there is an Integration for Nest Protect in HACS.

[@mostlychris]

I am aware but purposely not pushing it. It uses a method that potentially doesn't follow best practices and could go away at any time. Not a good thing for life and death devices.

[@smdemmery]

Wow that was a lot of steps great video all up & running for me thanks😁

[@Lowieken73]

Made it. At some moment I had to have input the wrong credentials, I had to delete them from the menu and create the correct ones. Once created Home Assistant keeps using them and starts at the project ID step, not the credentials step. But Things work now. This was a huge help !

[@pilotranee]

Had the same error after failing the first set-up. Revisited the integration with the help of this video but kept getting the "can't link to [name]" error. My credentials had carried over from my first attempt. Thank you for saving me a ton of time trying to Google the issue!

The fix was simple to remove the project from the device console and create a new one. Thanks for pointing that out in the video. I was afraid to remove that because I paid $5. lol

[@patricknelson]

Thanks. This sort of stuff is why I’m moving off of Google entirely (going all local), including their hardware. No longer want to be in the cloud and don’t want hardware that marries me to someone else’s server. That said, I’m here b/c I’m researching setting up HA to support my existing Nest Thermostat + Nest Doorbell for the time being until moving to better/alternative hardware (likely Ecobee + UniFi).

[@JussAren812]

[@fredjaquish]

That was a lot of steps, seems overly complicated, but finally Nest is linked to Home Assistant. I have ecobee and honeywell thermostats that were much easier to integrate. Thank you for the tutorial.

I don't hear that very often. Congratulations!

[@timothy-9995]

I actually found a way to do it for free! What I did is I set up Homebridge (I installed it on the same computer that runs my HA), then added my nest thermostat to Homebridge using the Homebridge Nest plugin (it's very easy with the UI). Then in Home Assistant, I added the integration "HomeKit Controller" (NOT "HomeKit", that caused me problems). Then I was able to control my Nest thermostat in Home Assistant.

[@mostlychris]

Always different ways to accomplish tasks in the IT world. Only thing is that you have one additional point of failure. Not a big deal if you are comfortable with that.

I went through this guide and added my first nest doorbell. Worked like a charm!

Thanks for this guide. Helped me migrate from WNN API as it finally died for me today... BTW there is a nest protect custom component on HACS. I will be checking it out too.

[@mostlychris]

Be careful with that. It uses a method that may stop working at any time. I considered making a video about that but found out from some developers at Google that it might be an issue with Google TOS.

[@jamesfryuk]

@@mostlychris Thanks good to know. Right now its working well (if a little differently from the WWN integration) and I will be happy to use it until it is broken by google. I have to say its a bit unsatisfatory how the older nest devices have not been properly supported by Google. Hopefully any deprecation of the unofficial API being used by this integration will be replaced with a formal API supporting nest protects instead
