older versions of the app make use of a legacy style webhook, this hook will become inactive April 4th. Please upgrade to newest version of the app!!!
Anchor point for Google Nest SDM app instructions, requests and issues.
BE AWARE THAT BATTERY POWERED DEVICES (CAM/DOORBELL) DO NOT SUPPORT GenerateImage and as such currently it will not show images of events.
Be aware that Google charges a one time 5$ fee to be able to use the Nest Device Access Platform and API (not the same as a donate to the developer of this app).
To be sure: this only works for Google accounts, NOT for old NEST accounts.
In the posts below there are the steps that the App will guide you through setting up the environment in Google.
Install the app and start configure app
Create a Google cloud project
Create the credentials for your cloud project
Enable API´s for your cloud project
Create the Device Access project.
It now supports NEST Protect using the old API interface with Google accounts. If you only have Nest Protect and no other Nest devices, you only need to setup the Legacy Nest tab in the app.
Using the same API it supports reporting on known faces and on-demand snapshots. Be aware that this ONLY applies to devices that are visible in the old NEST app, not the newer devices that are only added to Google Home.

Make sure that you enable all required devices and functions (all must be selected). The app is marked as unsave as it is not verified by Google. So just select advanced settings to continue.
