Running OpenClaw on a Raspberry Pi 5 — Complete 2026 Setup Guide
A $70 single-board computer running your personal AI assistant 24/7 for ~$4/year in electricity. Here's the full setup guide with real performance numbers.
Why Raspberry Pi for OpenClaw?
The Raspberry Pi 5 is the ultimate set-it-and-forget-it device. It draws about 5 watts of power — less than a phone charger — and runs completely silent. No fans, no noise, no heat issues in a well-ventilated case. It sits on your desk or in a closet and just... works.
For an OpenClaw setup that uses cloud-based AI models (Anthropic, OpenAI, Google), the Pi is more than powerful enough. OpenClaw doesn't run the AI models locally by default — it sends API calls to providers and orchestrates the responses. The Pi just needs to handle Node.js, maintain a Telegram WebSocket connection, and run a few cron jobs.
The killer advantage? Zero monthly hosting costs. You buy the Pi once ($70-90 for the 4GB model), and your only ongoing cost is electricity — roughly $4 per year. Compare that to even the cheapest VPS at $6/month ($72/year).
$0/month hosting
One-time hardware cost, then just electricity
Silent operation
No fans, no noise — perfect for home
~5W power draw
Less than a phone charger
What You Need
8GB model is nice-to-have but not required
Samsung EVO Select recommended
Official Pi 5 PSU recommended — don't cheap out
Argon ONE or Official Pi 5 case
Wi-Fi works, but wired is more reliable for 24/7
Faster I/O than SD card, better long-term reliability
Total cost: ~$95–130 one-time
That's less than one year of the cheapest VPS. After that, it's essentially free.
Full Setup Walkthrough
From unboxing to first Telegram message in about 45 minutes. Here's every step.
1Flash the OS
Download Raspberry Pi Imager and flash the latest Raspberry Pi OS Lite (64-bit) to your SD card. During setup, enable SSH and set a password.
2SSH In & Update
3Install OpenClaw
4Configure Auto-Start
Make sure OpenClaw starts automatically after reboots:
Done! Send "hello" to your Telegram bot.
Your Raspberry Pi is now running a 24/7 AI assistant. Response should come back in 2-5 seconds depending on your model.
Performance Reality
Let's be honest about what works and what doesn't on a Raspberry Pi 5.
| Metric | Raspberry Pi 5 (4GB) |
|---|---|
| Claude Sonnet response | 2.5–4s (API-bound, same as any device) |
| Gemini Flash response | 1.8–2.5s |
| RAM usage (idle) | 320–380 MB |
| RAM usage (active) | 400–550 MB |
| CPU usage (idle) | 2–5% |
| CPU temp (idle/active) | 38°C / 52°C (with passive cooling) |
| SD card usage | ~5 GB of 32 GB |
| Telegram reconnect time | <3 seconds after network blip |
What works great:
- All cloud-based AI models (Claude, GPT-5, Gemini, Kimi K2, Grok)
- Telegram bot — instant, always-on
- Cron jobs — morning briefs, monitoring, backups
- Web search, URL fetching, API calls
- Skills — weather, GitHub, calendar, email, etc.
- Light file processing (PDFs, text files)
What doesn't work well:
- ✕Local AI models (Ollama) — 4GB RAM is too limited for useful models
- ✕Heavy browser automation (Playwright) — works but slow
- ✕Large file processing (videos, huge PDFs)
- ✕Running multiple concurrent sub-agents (RAM limited)
Key insight
Response times are almost entirely determined by the AI provider's API, not your hardware. A Raspberry Pi and a $2,000 Mac Mini will get Claude Sonnet responses at the same speed. The Pi is only limited for local models and heavy compute tasks.
Power Consumption: ~$4/Year
The Raspberry Pi 5 draws about 3-5 watts at idle and up to 8 watts under load. For a 24/7 OpenClaw instance that's mostly idle (waiting for messages, occasionally running cron jobs), you're looking at an average of about 4.5 watts.
Electricity Cost Breakdown
Even in Europe with higher electricity prices, you're paying under €10/year to run a 24/7 AI assistant. That's less than one month of ChatGPT Plus.
Raspberry Pi vs $6/month VPS
Both are excellent choices. The right one depends on your situation.
| Factor | Raspberry Pi 5 | $6 VPS |
|---|---|---|
| Upfront cost | $95–130 | $0 |
| Monthly cost | ~$0.40 electricity | $6 |
| Annual cost (Year 1) | ~$100–135 | $72 |
| Annual cost (Year 2+) | ~$5 | $72 |
| RAM | 4–8 GB | 1 GB |
| Uptime | ~99% (home network) | 99.9% (datacenter) |
| Static IP | No (need DDNS or Tailscale) | Yes |
| Local AI models | Limited (4GB) | No (1GB) |
| Maintenance | SD card wear, power outages | Managed by provider |
| Remote access | Needs setup (Tailscale, etc.) | Always accessible |
🍓 Choose Raspberry Pi if:
- • You want zero monthly costs
- • You have reliable home internet
- • You enjoy tinkering with hardware
- • You already own a Pi
- • Privacy is a top priority (all local)
☁️ Choose VPS if:
- • You want maximum uptime/reliability
- • You need a static IP address
- • You travel and need guaranteed access
- • You don't want hardware maintenance
- • You want to start in 10 minutes
The Verdict
The Raspberry Pi 5 is a genuinely great platform for OpenClaw. For the core use case — a Telegram-connected AI assistant running cloud-based models with cron automations — it performs identically to much more expensive hardware. The API latency is the bottleneck, not the Pi.
After the initial hardware cost, you're looking at essentially free hosting for years. If you already have a Pi lying around, there's literally no reason not to try it. If you're buying new, you'll break even vs a $6/month VPS in about 16 months — and then it's all savings from there.
The only real limitation is reliability. Home internet goes down, power flickers, SD cards wear out. If you need 99.9% uptime and guaranteed accessibility from anywhere, a VPS is the safer bet. But for a personal assistant that's available "most of the time"? The Pi is hard to beat.
