What Google Nest devices are supported by this API?

The SDM API supports: Nest Thermostats (Nest Learning Thermostat, Nest Thermostat E, Nest Thermostat 2020), Nest Cameras (legacy, battery, wired, with spotlight), Nest Doorbells (legacy battery, wired, battery), and Nest Hub displays. Each device exposes specific traits (e.g., ThermostatMode, CameraLiveStream) that can be queried and controlled.

How do I get OAuth 2.0 credentials for the Google SDM API?

Visit the [**Google Device Access console**](https://console.nest.google.com/device-access/) and create a project. You'll receive a Project ID. Then, set up OAuth 2.0 credentials in Google Cloud Console, link them to your Device Access project, and complete the OAuth flow to obtain an access token. The token expires after 1 hour and must be refreshed.

Can I control multiple thermostats in different locations?

Yes! The API returns all devices across all structures and rooms in your project. Use `list_devices` to see all thermostats with their room assignments, then use each device's unique ID to control them individually. You can set different modes and temperatures for each thermostat.

How long do camera stream URLs last?

Camera stream URLs (both RTSP and WebRTC) are temporary and typically expire after 5 minutes. The stream token returned in the response should be used immediately and the stream should be stopped with `stop_camera_stream` when no longer needed to free up device resources.

12 tools expose this connector's capabilities to your AI agent.

list_rooms

Useful for understanding device locations and room organization. List all rooms in a specific structure

list_structures

Each structure contains rooms and devices. List all structures (homes) in your Google Nest account

set_fan_timer

Turns the fan on for a specified duration. Duration is optional and defaults to the thermostat setting. Set the fan timer on a Nest thermostat

generate_camera_stream

The stream token is temporary and should be used immediately. Stop the stream when done. Generate a live camera stream URL from a Nest camera or doorbell

get_device

Use device ID from list_devices or device name. Get details for a specific Google Nest device

list_devices

Shows device types, traits, and room assignments. USE WHEN: - User wants to see all their Nest devices - User needs to find device IDs for other commands - User is exploring their smart home setup - User asks "what Nest devices do I have" EXAMPLES: - "List all my Nest devices" → call with no params - "Show my smart home devices" → call with no params - "What Nest devices are connected?" → call with no params List all Google Nest devices in your home

set_thermostat_range

Useful for HEATCOOL mode to define the comfort range. Set both heating and cooling temperatures on a Nest thermostat

stop_camera_stream

Use the stream token returned from generate_camera_stream to properly terminate the stream session. Stop an active camera stream from a Nest camera or doorbell

set_thermostat_cool

Use this when the thermostat is in COOL or HEATCOOL mode. Set the cooling temperature on a Nest thermostat

set_thermostat_eco

This is a manual override of the eco/eco-friendly temperature settings. Set Nest thermostat to eco mode for energy savings

set_thermostat_heat

Use this when the thermostat is in HEAT or HEATCOOL mode. Set the heating temperature on a Nest thermostat

set_thermostat_mode

Supported modes: HEAT, COOL, HEATCOOL, OFF. Use device ID from list_devices to target a specific thermostat. USE WHEN: - User wants to change thermostat mode - User asks to turn heating/cooling on or off - User wants to switch thermostat operating mode - User says "set thermostat to heat/cool/off" PARAMETERS: - device_id (REQUIRED): Thermostat device ID - mode (REQUIRED): One of HEAT, COOL, HEATCOOL, or OFF EXAMPLES: - "Set thermostat to heat mode" → call with device_id, mode="HEAT" - "Turn off the thermostat" → call with device_id, mode="OFF" - "Set thermostat to cool" → call with device_id, mode="COOL" Set the mode of a Nest thermostat
