# Device Access Project

As a last step you need to create the Sandbox environment for the Nest Device Access Project. After creation of the project the Project Id needs to be copied into PROJECT ID field of the Homey Nest SDM app.  

If you have never used the Device Access Console, you need to pay a one time fee of 5$ to Google gain access to the sandbox development environment of the Nest Devices Access API.
