Works With Nest - Deprecating on August 31, 2019

Based on everything Google has said this far, there will be no way to connect it to OH. They are only slowing a small set of heavily vetted third parties to connect to and get any data from Nest devices. If IFTTT didn’t make the cut, what chance does a small open source project have? Even Alexa support isn’t a guarantee right now.

Best products are only going to be guaranteed to work with Google Assistant.

I guess, you are right. Then the question would be: Which new functionality will Google Assistant have in the future? openHAB is already connected to Google Assistant.

OpenHAB is connected to Google Assistant in the same way that Hue is connected to GA. OH provides sensor readings and the ability to control devices to GA. The integration is not reciprocal. GA provides no sensor readings it ability to control things to OH. And they explicitly stated this is by design.

So for all practical purposes, all Nest products are I longer compatible with OH. And unless Google changes their position and allow more than a few carefully vetted third parties, they will remain incompatible with OH.

Does anybody remember back when Google’s whole motto was “Don’t be evil”?..

Yeah me neither.

Google is a very large, for-profit company, and like any other company the individual employees make good and bad decisions. I don’t even think this was a particularly bad decision in the grand scheme of things…in my opinion, it was just executed poorly.

There are lots of times where I’ve made decisions that put the best interests of the majority ahead of others. I never like doing it, but it’s often necessary to move forward. There are even more times when I’ve heard about similar “needs of the many” decisions and agreed with them, because I’m not personally affected. So I can’t be upset when I’m in the minority. And in this case, OH users are clearly in the minority.

Everyone’s experience with Google varies. I’ve received a lot of free service from them over the years for the cost of advertisements customized to my interests and data that I’m personally comfortable with giving them. They provide, for free, a Google for Non-profits account that provides my charity with web-based services we couldn’t otherwise afford. And when I fire up the free Chrome browser to search for something random or check GMail, they still don’t charge me any money.

Your experience with Google will obviously be different from mine, but if you want to label them as evil, then I hope you’re doing your best to avoid using their services at any cost–financial or otherwise. I also hope you’re aware of the far-more questionable and underhanded practices of many other for-profit companies. Compared to what some others will do to generate profits, Google looks pretty good to me.


just to be sure I’ve understood correctly. The as-is will stay as-is, I mean there won’t be disconnections on 31st of August. But they won’t accept new connections, and existing users won’t receive updates/new features.

Is that correct?

I mean, my current Protect will continue working with OH …

For a time and with stipulations.

  1. Do not convert your login to log in with Google. You must keep your Nest log in.

  2. They will shut the API down, probably by the end of the year. Google hasn’t promised to keep it running forever or even for a long time. They have only given us an extension to when the API will be closed down.

You have more time, but your current Protect will stop working with OH sometime soon, probably by the end of the year.

And … there are no other options to work with … ?

I mean, improve Google / OH interactions …

No, there is not. openHAB is not among and will never be among the “heavily vetted third-party systems” who are the only ones that Google will allow access to any data from Nest products. Google wants Google Assistant to be the hub. All information goes there and they want to control everything.

If IFTTT is definitely not going to be supported by Google and even Alexa support is in doubt, there is no chance that a smallish open source project like openHAB will ever be allowed access by Google. Make no mistake, this is all on Google’s side and it’s all Google’s doing.

Homebridge plugin (3.0.0) is able to work with Nest without those APIs …

Maybe a way there?

Maybe? I really would like my Nest Protects to work with OpenHAB again.

@ariela @Ben_Douglas How are your Nest Protects integrated into openHAB, and what do you do with them?

I looked at integrating my Nest Protect (before Google’s announcements) to take advantage of the Away state, but didn’t feel like I was gaining enough functionality to justify the time and effort. I’m curious as to how others have benefited and if I’ve missed seeing some opportunities.

ciao Russell,

at the moment I’m just collecting info about:

  • Overall System (eg. green)
  • CO Alarm state (eg. OK)
  • Smoke Alarm state (eg. OK)
  • battery
  • Nest Protect Test in progress (is a switch item, ON when a test is in progress, good to avoid false positives due to test in progress)
  • Nest mode (eg. Home)

The Home/Away state is tricky, I don’t see any change even if my Nest is connected to my Mercedes ( and it should be “away” when I drive out of a specific range from home.

I would like to maintain the same level, also with new Nest devices … and maybe improve and solve the mercedes issue


The HomeBridge project appears to have found a way around these restrictions. It might be clunky to try and control the HomeBridge device from openHAB but I still think I’ll try.

I was using the smoke and CO state in a rule to turn on all the lights in the house should an alarm go off. I also was using the motion sensors in the Protects as a sort of presence sensor so OpenHAB would know the home was occupied.
I had to reinstall OpenHAB and went to authorize Nest again and was unable to get to the developer console to get the pin and such. So now my Nest Protects are no longer part of my OpenHAB system until a way is found to connect them again.:unamused:

I didn’t realize you could use the motion detector, or are you referring to the Home/Away mode?

Are you going to give homebridge a shot, or wait for @Dome to experiment first? :wink:

I was not able to log into developer consol. I was forced to use my google account to log in. I have CO detector and Nest Hello.

Has there been a new working solution to get Nest devices on Openhab?

Or is the solution moving away from Nest

As far as I know the solution would be to move away from Nest since they explicitly state they will only allow a few select partners access to their products.
Anything else would involve screen scraping or other workarounds.

Well this could be promising news. Not only is Google releasing a “Device Access Program” for partners, they are also working on a “Device Access Program” for individuals!
