In a world increasingly oriented towards smart technology, having your own AI-powered home assistant can be a game changer. This guide will lead you through the process of building your very own GPT home assistant using a Raspberry Pi and the OpenAI API. Think of it as crafting your personal version of Google Nest Hub or Amazon Alexa, but with a sprinkle of DIY magic!

What You’ll Need

• Core Components:
  • Raspberry Pi 4B: Link – $50-$70
  • Mini Speaker: Link – $18
  • 128 GB MicroSD card: Link – $13
  • USB 2.0 Mini Microphone: Link – $8
• Optional Components:
  • 128×32 OLED Display: Link – $13-$14
  • Raspberry Pi UPS Power Supply with Battery: Link – $30

Let’s Dive In

Now that you have your parts, let’s start with the essential instructions to set up your GPT home assistant.

Step 1: Exporting Your OpenAI API Key

To ensure that your new assistant can communicate with OpenAI, you’ll need to export your API key to an environment variable.

echo export OPENAI_API_KEY=your_api_key_here >> ~/.bashrc
source ~/.bashrc

Step 2: Run the Setup Script

Execute the setup script to pull the latest image from DockerHub:

curl -s https://raw.githubusercontent.com/judahpaul16/gpt-home/main/contrib/setup.sh | bash -s -- --no-build

Wi-Fi Configuration

To get your Raspberry Pi online, you’ll need to configure Wi-Fi using a bash script. Here’s how:

1. Create the bash script to configure Wi-Fi:

sudo nano /usr/local/bin/start_wifi.sh

2. Add this content to the script:

#!bin/bash
INTERFACE=wlan0
SSID=your_wifi_ssid
PASSWORD=your_wifi_password
sudo killall wpa_supplicant
sudo dhcpcd -x $INTERFACE
sudo ip link set $INTERFACE up
WPA_CONF=/etc/wpa_supplicant/wpa_supplicant.conf
wpa_passphrase $SSID $PASSWORD | sudo tee $WPA_CONF > /dev/null
sudo wpa_supplicant -B -i $INTERFACE -c $WPA_CONF
sudo dhcpcd $INTERFACE

3. Make the script executable:

sudo chmod +x /usr/local/bin/start_wifi.sh

4. Create a systemd service file:

sudo nano /etc/systemd/system/start_wifi.service

5. Add the following content:

[Unit]
Description=Start WiFi at boot
After=network.target

[Service]
ExecStart=/usr/local/bin/start_wifi.sh
RemainAfterExit=true

[Install]
WantedBy=multi-user.target

6. Reload systemd and enable the service:

sudo systemctl daemon-reload
sudo systemctl enable start_wifi.service
sudo systemctl start start_wifi.service

Building the Docker Container

Your setup script will also require a good deal of time to complete:

export OPENAI_API_KEY=your_api_key_here

This command effectively allows your Raspberry Pi to authenticate and use your OpenAI API key for operations. Alternatively, you can refer to the LiteLLM documentation for integrating different models.

Testing and Using Your GPT Home Assistant

Once all the steps are completed, you should be able to interact with your new assistant! If it behaves unexpectedly, fear not—troubleshooting is part of the journey.

Troubleshooting

• If you encounter issues, ensure your API keys are correctly set in the environment variables.
• Check if the Docker service is running with sudo systemctl status docker.
• Review the logs for the Docker container with docker logs gpt-home to diagnose any failure notices.
