  • Custom automation: Trigger lights, locks, or alarms based on doorbell events using tools like Home Assistant.
  • Offline functionality: Reduce dependency on internet connectivity by processing video locally.
  • Extended features: Add two-way audio to non-supported models, enable continuous recording, or integrate with security systems.
  • Cost savings: Avoid subscription fees for Nest Aware by using local storage solutions.

Now, let’s get into the how.

Prerequisites: What You’ll Need

Before you start hacking, make sure you have the following:

Hardware Requirements

  • Nest Doorbell (wired or battery): Any model works, but wired versions are easier to modify due to constant power.
  • Micro-USB cable (for wired models): Used for initial setup and potential firmware access.
  • Raspberry Pi or local server: For running local services like RTSP servers or Home Assistant.
  • MicroSD card (16GB+): If using a Raspberry Pi.
  • Stable Wi-Fi network: Your doorbell and local server must be on the same network.

Software & Accounts

  • Google Account: Required to set up the Nest Doorbell initially.
  • Home Assistant (optional but recommended): Open-source home automation platform.
  • Node-RED (optional): Visual tool for wiring together hardware devices and APIs.
  • IFTTT account (optional): For simple automations without coding.
  • SSH client (like PuTTY or Terminal): For accessing your Raspberry Pi or server.

Skills & Mindset

  • Basic networking knowledge: Understand IP addresses, ports, and Wi-Fi settings.
  • Comfort with command line: You’ll use terminal commands for setup.
  • Patience and troubleshooting mindset: Things may not work on the first try.
  • Willingness to learn: This isn’t a plug-and-play solution—expect to experiment.

Step 1: Set Up Your Nest Doorbell Normally

Before you can hack it, you need to set up your Nest Doorbell using the official Google Home app. This ensures the device is properly registered and functioning.

Install the Google Home App

Download the Google Home app on your smartphone (iOS or Android). Sign in with your Google account.

Pair the Doorbell

  1. Open the app and tap the “+” icon to add a device.
  2. Select “Set up device” > “New device.”
  3. Choose your home and follow the on-screen instructions.
  4. Scan the QR code on your Nest Doorbell or enter the setup code manually.
  5. Connect the doorbell to your Wi-Fi network.
  6. Complete the setup, including motion zones and notification preferences.

Once set up, test the doorbell by pressing it or triggering motion. Make sure you receive alerts and can view live video.

Why This Step Matters

Even if you plan to bypass Google’s cloud later, the initial setup is necessary to activate the device and ensure hardware functionality. Skipping this step can lead to errors during hacking attempts.

Step 2: Enable Developer Mode (If Available)

As of now, Google does not officially support developer mode on Nest Doorbells. However, some older models or firmware versions may have hidden access points. This step is speculative but worth mentioning.

Check for Hidden Menus

Some users have reported accessing debug menus by:

  • Pressing and holding the doorbell button for 10+ seconds during setup.
  • Using specific QR codes or NFC tags during pairing.
  • Interrupting the firmware update process.

These methods are unreliable and may brick your device. Proceed only if you’re comfortable with the risk.

Alternative: Use Google’s Public APIs

Instead of hacking the firmware directly, use Google’s Works with Nest or Google Home API to interact with your doorbell programmatically.

Steps:

  1. Go to the Google Device Access Console.
  2. Create a project and enable the Smart Device Management API.
  3. Register your Nest Doorbell as a device.
  4. Use OAuth 2.0 to authenticate and access device data.

This method is legal, safe, and doesn’t void your warranty. You can read events like doorbell presses and motion alerts, though video access is limited.

Step 3: Enable RTSP Streaming (Local Video Access)

One of the most popular hacks for the Nest Doorbell is enabling RTSP (Real-Time Streaming Protocol). This allows you to stream video directly to local devices like security NVRs or media servers—no cloud needed.

Why RTSP?

  • Video stays on your local network.
  • No subscription fees.
  • Works with VLC, Blue Iris, Synology Surveillance Station, etc.
  • Reduces latency compared to cloud streaming.

How to Enable RTSP on Nest Doorbell

Unfortunately, Google does not officially support RTSP. But the community has found workarounds using reverse engineering and local proxies.

Method: Use a Local RTSP Proxy (e.g., rtsp-simple-server)

This method involves setting up a local server that mimics a Nest-compatible stream and tricks the doorbell into sending video to it.

Step-by-Step:
  1. Set up a Raspberry Pi or local server: Install Raspberry Pi OS or Ubuntu.
  2. Install rtsp-simple-server: This open-source tool creates an RTSP endpoint.

Open a terminal and run:

wget https://github.com/aler9/rtsp-simple-server/releases/latest/download/rtsp-simple-server_linux_arm64v8.tar.gz
tar -xzf rtsp-simple-server_linux_arm64v8.tar.gz
./rtsp-simple-server
  1. Configure the server: Edit the config file to allow incoming streams.
  2. Use a Nest RTSP hack script: Community tools like nest-rtsp (GitHub) can intercept the doorbell’s video feed.
  3. Redirect traffic: Use DNS spoofing or a local proxy to route the doorbell’s video requests to your RTSP server.
  4. Test the stream: Open VLC and enter rtsp://[your-server-ip]:8554/nest.

Troubleshooting RTSP Issues

  • No video: Check firewall settings—port 8554 must be open.
  • Lag or stuttering: Ensure your network has sufficient bandwidth.
  • Connection drops: The doorbell may disconnect if it detects an unauthorized stream. Reboot and retry.
  • Privacy warning: Some hacks require disabling encryption, which reduces security. Use only on trusted networks.

Step 4: Integrate with Home Assistant

Home Assistant is a powerful open-source platform for smart home automation. It supports thousands of devices, including Nest (with limitations).

Install Home Assistant

You can run Home Assistant on a Raspberry Pi, virtual machine, or dedicated server. Follow the official installation guide at home-assistant.io.

Add Nest Doorbell via Google Home API

  1. In Home Assistant, go to Settings > Devices & Services > Add Integration.
  2. Search for “Google Home” and select it.
  3. Log in with your Google account and authorize access.
  4. Your Nest Doorbell should appear in the device list.
  5. Enable entities like “doorbell pressed” and “motion detected.”

Create Custom Automations

Now you can create automations based on doorbell events.

Example: Turn on porch lights when motion is detected.

  1. Go to Settings > Automations & Scenes > Create Automation.
  2. Trigger: “Device” > Select your Nest Doorbell > “Motion detected.”
  3. Action: “Call Service” > “light.turn_on” > Select your porch light.
  4. Save and test.

Advanced: Use Node-RED for Complex Logic

Node-RED is a visual programming tool that integrates with Home Assistant. You can create flows like:

  • Send a Telegram message when the doorbell rings.
  • Record video to a local drive when motion is detected.
  • Play a custom sound on a smart speaker.

Step 5: Local Storage and Recording

Google’s Nest Aware subscription is expensive. Hacking allows you to record footage locally for free.

Option 1: Use MotionEyeOS

MotionEyeOS is a lightweight Linux distribution that turns a Raspberry Pi into a security camera recorder.

  1. Flash MotionEyeOS to a microSD card.
  2. Insert into Raspberry Pi and connect to power and network.
  3. Access the web interface at http://[pi-ip]:8765.
  4. Add your RTSP stream (from Step 3) as a camera source.
  5. Configure recording schedules and motion detection.

Option 2: Use Synology Surveillance Station

If you have a Synology NAS, you can add the RTSP stream as a camera and record 24/7.

Option 3: Custom Script with FFmpeg

Use FFmpeg to record video from the RTSP stream to a local file.

ffmpeg -i rtsp://[server]:8554/nest -c copy -f segment -strftime 1 "recordings/%Y-%m-%d_%H-%M-%S.mp4"

This saves hourly recordings with timestamps.

Step 6: Custom Notifications and Alerts

Google’s notifications are basic. Hacking lets you customize alerts.

Use IFTTT for Simple Alerts

  1. Create an IFTTT account and connect Google Home.
  2. Create an applet: “If Nest Doorbell detects motion, then send a push notification.”
  3. Add custom text like “Motion at front door!”

Use Telegram or Slack for Team Alerts

With Home Assistant, you can send alerts to messaging apps.

service: notify.telegram
data:
  message: "Someone is at the door!"
  title: "Nest Alert"

Play Custom Sounds

Use a smart speaker to play a doorbell chime or alert sound when the button is pressed.

Step 7: Security and Maintenance

Hacking introduces risks. Follow these best practices:

Keep Firmware Updated

Google may patch vulnerabilities that your hacks rely on. Monitor forums like Reddit’s r/Nest or GitHub for updates.

Use Strong Passwords

Change default passwords on your Raspberry Pi, router, and any local services.

Enable Two-Factor Authentication

On your Google account and any admin panels.

Regularly Back Up Configurations

Save copies of your Home Assistant config, RTSP settings, and scripts.

Monitor Network Traffic

Use tools like Wireshark to check for unexpected data leaks.

Troubleshooting Common Issues

Even with careful planning, things can go wrong. Here’s how to fix common problems.
