+# 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
+
+## Setup
+
+<Steps>
+  <Step title="Flash the OS">
+    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.
+
+  </Step>
+
+  <Step title="Connect via SSH">
+    ```bash
+    ssh user@gateway-host
+    ```
+  </Step>
+
+  <Step title="Update the system">
+    ```bash
+    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
+    ```
+
+  </Step>
+
+  <Step title="Install Node.js 24">
+    ```bash
+    curl -fsSL https://deb.nodesource.com/setup_24.x | sudo -E bash -
+    sudo apt install -y nodejs
+    node --version
+    ```
+  </Step>
+
+  <Step title="Add swap (important for 2 GB or less)">
+    ```bash
+    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
+    ```
+
+  </Step>
+
+  <Step title="Install OpenClaw">
+    ```bash
+    curl -fsSL https://openclaw.ai/install.sh | bash
+    ```
+  </Step>
+
+  <Step title="Run onboarding">
+    ```bash
+    openclaw onboard --install-daemon
+    ```
+
+    Follow the wizard. API keys are recommended over OAuth for headless devices. Telegram is the easiest channel to start with.
+
+  </Step>
+
+  <Step title="Verify">
+    ```bash
+    openclaw status
+    systemctl --user status openclaw-gateway.service
+    journalctl --user -u openclaw-gateway.service -f
+    ```
+  </Step>
+
+  <Step title="Access the Control UI">
+    On your computer, get a dashboard URL from the Pi:
+
+    ```bash
+    ssh user@gateway-host 'openclaw dashboard --no-open'
+    ```
+
+    Then create an SSH tunnel in another terminal:
+
+    ```bash
+    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).
+
+  </Step>
+</Steps>
+
+## 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](https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#usb-mass-storage-boot).
+
+**Enable module compile cache** -- Speeds up repeated CLI invocations on lower-power Pi hosts:
+
+```bash
+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
+echo 'gpu_mem=16' | sudo tee -a /boot/config.txt
+sudo systemctl disable bluetooth
+```
+
+## Troubleshooting
+
+**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 --user -u openclaw-gateway.service --no-pager -n 100` and run `openclaw doctor --non-interactive`. If this is a headless Pi, also verify lingering is enabled: `sudo loginctl enable-linger "$(whoami)"`.
+
+**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`.
