Is Google Nest support still wanted?

b03tz · February 11, 2021, 6:01pm

I couldn’t help but notice there is no google nest support. I have written an app that integrates with google’s new Smart Device Management API and I have my doorbell working with motion / sound / chime (button pressed) triggers.

I currently just use it privately as it’s a bit of a mess but if there’s any interest I might clean up the code and release it. The way this integration works should also make it possible for other devices to work relatively easy. It’s even possible to download camera event image sources to do stuff with (I haven’t tried this yet).

Let me know!

[edit]
As a heads up; this method (the API) requires you to register at Device Access Registration | Google Developers for a one time $5 fee

Yes please!
As I understand you could also make it work with Nest Protect?

Hello! I‘m also very interested!

Currently I only see support for Camera, Display, Doorbell and Thermostat in the docs: Smart Device Management API | Device Access | Google Developers

I’d love google thermostat!

Oeh, yes, Please!!!

I still run my thermostat on the old api, but a new app would be nice!

I really want to make the thermostat code as well; but I don’t own a Google Thermostat (got the Tado running). I hope I can integrate it without having the actual device.

Think lots of guys are willing to test it!

Yes please

I edited the main post; just so you know: Google requires you to pay $5 (as a one time fee) to be able to use the Device Access Registration

That would be great if the Nest thermostat and possibly the Nest Protect can be added to Homey again. Really looking forward to it.

Oh yes need that too so much of course!

Mark1541 · February 11, 2021, 7:13pm

Yes and big yes

Mark1541 · February 11, 2021, 7:15pm

I hope you can release it soon or a beta ?

Oh man, Google has made it so hard to be able to subscribe to events (which is at least neccesary for a doorbell to function).

Can some of you guys read this and tell me if this would make you not use this plugin: (be sure to click the link, it’s alot longer then the forum shows)

# Google Nest Doorbell

Integration of Google Nest Doorbell events (chime, motion, sound)

# How to get Google API credentials
You should first grab a cup of coffee. No really, do it. This stuff is going to be intense. As far as I know this is the only way to subscribe to Google's Smart Device Management events. I have no idea why they made it this hard but I hope I can pull you through this. It requires you to pay a $5 fee to Google as a one time 'developer' fee.

After that the process consists of:
* Creating an OAuth client
* Creating a project in Google's Device Access Console
* Link the OAuth client to the new project
* Create a subscription (for your events)
* Create a service account that can access this subscription
* Enter the data you gathered into the Google Nest Homey plugin

## Create an OAuth Client ID
* Visit: https://console.cloud.google.com/apis/credentials
* Click "+ Create credentials" on top of the page
* Pick "OAuth Client ID"
* Application type: "Web application"

I have tried to make it as clear as possible, but it’s just really hard the way Google did this. This is the information the app would need to be able to have a working subscription that can handle events.

Really nice that youre making an app for the nest ! is it only going to support the doorbell? i have a nest thermostat really like to use it in homey

b03tz · February 12, 2021, 9:12am

Hey Wesley, what functionality do you want from your thermostat? I can see the API provides commands to: Set temperature, set mode, change the temperature setpoints (heat point, cool point).

If you want to show your current temperature you would also need to subscribe to the event API using the same method. Since your thermostat will send a temperature update event in the subscription which the Homey app should respond to (set the device value to that target temperature, etc)

wesley_w · February 12, 2021, 8:09pm

Yes please!!

That would be awesome: Thermostat / Doorbell + image / Camera’s

If you release this working app you can receive the pledge
