Raspberry Pi

Run a persistent, always-on OpenClaw Gateway on a Raspberry Pi. Since the Pi is just the gateway (models run in the cloud via API), even a modest Pi handles the workload well.

Prerequisites

  • Raspberry Pi 4 or 5 with 2 GB+ RAM (4 GB recommended)
  • MicroSD card (16 GB+) or USB SSD (better performance)
  • Official Pi power supply
  • Network connection (Ethernet or WiFi)
  • 64-bit Raspberry Pi OS (required — do not use 32-bit)
  • About 30 minutes

安装配置

Use Raspberry Pi OS Lite (64-bit) — no desktop needed for a headless server.

1. Download [Raspberry Pi Imager](https://www.raspberrypi.com/software/).
2. Choose OS: **Raspberry Pi OS Lite (64-bit)**.
3. In the settings dialog, pre-configure:
   * Hostname: `gateway-host`
   * Enable SSH
   * Set username and password
   * Configure WiFi (if not using Ethernet)
4. Flash to your SD card or USB drive, insert it, and boot the Pi.

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
ssh user@gateway-host

“`bash theme={“theme”:{“light”:”min-light”,”dark”:”min-dark”}}
sudo apt update && sudo apt upgrade -y
sudo apt install -y git curl build-essential

# Set timezone (important for cron and reminders)
sudo timedatectl set-timezone America/Chicago
```

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
curl -fsSL https://deb.nodesource.com/setup_24.x | sudo -E bash -
sudo apt install -y nodejs
node --version

“`bash theme={“theme”:{“light”:”min-light”,”dark”:”min-dark”}}
sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo ‘/swapfile none swap sw 0 0’ | sudo tee -a /etc/fstab

# Reduce swappiness for low-RAM devices
echo 'vm.swappiness=10' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
```

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
curl -fsSL https://openclaw.ai/install.sh | bash

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
openclaw onboard --install-daemon

Follow the wizard. API keys are recommended over OAuth for headless devices. Telegram is the easiest channel to start with.

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
openclaw status
sudo systemctl status openclaw
journalctl -u openclaw -f

On your computer, get a dashboard URL from the Pi:

```bash  theme={"theme":{"light":"min-light","dark":"min-dark"}}
ssh user@gateway-host 'openclaw dashboard --no-open'
```

Then create an SSH tunnel in another terminal:

```bash  theme={"theme":{"light":"min-light","dark":"min-dark"}}
ssh -N -L 18789:127.0.0.1:18789 user@gateway-host
```

Open the printed URL in your local browser. For always-on remote access, see [Tailscale integration](/gateway/tailscale).

Performance tips

Use a USB SSD — SD cards are slow and wear out. A USB SSD dramatically improves performance. See the Pi USB boot guide.

Enable module compile cache — Speeds up repeated CLI invocations on lower-power Pi hosts:

“`bash theme={“theme”:{“light”:”min-light”,”dark”:”min-dark”}}
grep -q ‘NODE_COMPILE_CACHE=/var/tmp/openclaw-compile-cache’ ~/.bashrc || cat >> ~/.bashrc <<‘EOF’ # pragma: allowlist secret
export NODE_COMPILE_CACHE=/var/tmp/openclaw-compile-cache
mkdir -p /var/tmp/openclaw-compile-cache
export OPENCLAW_NO_RESPAWN=1
EOF
source ~/.bashrc


**Reduce memory usage** -- For headless setups, free GPU memory and disable unused services:

```bash  theme={"theme":{"light":"min-light","dark":"min-dark"}}
echo 'gpu_mem=16' | sudo tee -a /boot/config.txt
sudo systemctl disable bluetooth

故障排查

Out of memory — Verify swap is active with free -h. Disable unused services (sudo systemctl disable cups bluetooth avahi-daemon). Use API-based models only.

Slow performance — Use a USB SSD instead of an SD card. Check for CPU throttling with vcgencmd get_throttled (should return 0x0).

Service will not start — Check logs with journalctl -u openclaw --no-pager -n 100 and run openclaw doctor --non-interactive.

ARM binary issues — If a skill fails with “exec format error”, check whether the binary has an ARM64 build. Verify architecture with uname -m (should show aarch64).

WiFi drops — Disable WiFi power management: sudo iwconfig wlan0 power off.
