--- summary: "Host OpenClaw on a Raspberry Pi for always-on self-hosting" read_when: - Setting up OpenClaw on a Raspberry Pi - Running OpenClaw on ARM devices - Building a cheap always-on personal AI title: "Raspberry Pi" --- # 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 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 ssh user@gateway-host ``` ```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 ``` ```bash curl -fsSL https://deb.nodesource.com/setup_24.x | sudo -E bash - sudo apt install -y nodejs node --version ``` ```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 ``` ```bash curl -fsSL https://openclaw.ai/install.sh | bash ``` ```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. ```bash openclaw status sudo systemctl status openclaw journalctl -u openclaw -f ``` 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). ## 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 -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`. ## Next steps - [Channels](/channels) -- connect Telegram, WhatsApp, Discord, and more - [Gateway configuration](/gateway/configuration) -- all config options - [Updating](/install/updating) -- keep OpenClaw up to date
