- Connect Even Realities G2 smart glasses to OpenClaw via Cloudflare Worker. Deploys a bridge that routes G2 voice commands to your OpenClaw Gateway — same agent, same memory, same tools, just voice instead of typing. Supports short conversations (direct reply on glasses), long tasks (background processing with Telegram delivery), and image generation (DALL-E → Telegram). Use when: setting up G2 glasses with OpenClaw, deploying the G2 bridge worker, or troubleshooting G2 ↔ OpenClaw connectivity.

Even Realities G2 × OpenClaw Bridge
Deploy a Cloudflare Worker that connects Even Realities G2 smart glasses to your OpenClaw Gateway.
What It Does
G2 Glasses → (voice→text) → CF Worker → OpenClaw Gateway → Full Agent
↓ ↓
G2 display (text) Telegram (rich content)- Short tasks (chat, questions): Gateway responds → displayed on G2
- Long tasks (write code, articles): G2 shows "Working on it..." → result sent to Telegram
- Image generation: DALL-E generates → sent to Telegram (G2 can't show images)
- Fallback: If Gateway is down, falls back to direct Claude API
Prerequisites
- Even Realities G2 glasses with Even app (v0.0.7+ with "Add Agent" support)
- OpenClaw Gateway with HTTP API enabled
- Cloudflare account (free plan works)
- Anthropic API key (fallback)
- Optional: OpenAI API key (image gen), Telegram bot token (rich content delivery)
Setup
1. Enable OpenClaw Gateway HTTP API
On your OpenClaw host, enable the chat completions endpoint:
openclaw config set gateway.http.endpoints.chatCompletions.enabled true
openclaw gateway restartVerify:
curl -X POST https://YOUR_GATEWAY_URL/v1/chat/completions \
-H "Authorization: Bearer YOUR_GATEWAY_TOKEN" \
-H "Content-Type: application/json" \
-d '{"model":"openclaw","messages":[{"role":"user","content":"hi"}]}'2. Deploy Cloudflare Worker
Copy scripts/worker.js to your project, then deploy:
# Install wrangler
npm install -g wrangler
# Login to Cloudflare
wrangler login
# Deploy
wrangler deployOr use the Cloudflare Dashboard: Workers & Pages → Create → Upload worker.js.
3. Set Secrets
# Required
wrangler secret put GATEWAY_URL # Your OpenClaw Gateway URL
wrangler secret put GATEWAY_TOKEN # Your Gateway auth token
wrangler secret put G2_TOKEN # Token for G2 glasses auth (you choose)
wrangler secret put ANTHROPIC_API_KEY # Fallback when Gateway is down
# Optional (for Telegram delivery of rich content)
wrangler secret put TELEGRAM_BOT_TOKEN
wrangler secret put TELEGRAM_CHAT_ID
# Optional (for image generation)
wrangler secret put OPENAI_API_KEY4. Configure G2 Glasses
In Even app → Settings → Add Agent:
- Name: Your agent name (e.g., "Cloud Lobster")
- URL:
https://YOUR_WORKER.workers.dev - Token: The
G2_TOKENyou set above
5. Test
curl -X POST https://YOUR_WORKER.workers.dev \
-H "Authorization: Bearer YOUR_G2_TOKEN" \
-H "Content-Type: application/json" \
-d '{"model":"openclaw","messages":[{"role":"user","content":"Hello, who are you?"}]}'Architecture
Request Flow
- G2 converts speech → text, sends as OpenAI chat completion format
- Worker authenticates via
G2_TOKEN - Worker classifies request:
- Image gen → DALL-E + Telegram (immediate G2 ack) - Long task → immediate G2 ack + background Gateway call → Telegram - Short task → proxy to Gateway → return to G2
- Gateway runs full agent loop (memory, tools, skills)
- Response filtered for G2 display (no URLs, code blocks → Telegram)
Security
Two-layer token auth:
G2 --[G2_TOKEN]--> Worker --[GATEWAY_TOKEN]--> Gateway- G2 only knows
G2_TOKEN— if glasses are lost, change only this token GATEWAY_TOKENstays in Worker secrets, never exposed to glasses- Gateway HTTP API should be behind auth (token or password mode)
G2 Display Limitations
- 576×136 pixels, monochrome green, ~48 chars wide
- Text only (no images, no markdown rendering)
- Worker auto-filters: URLs →
[link], code blocks →[code], long text → truncated - Non-displayable content forwarded to Telegram
Customization
Edit the task classification regex in worker.js:
isLongTask()— patterns that trigger background processingisImageGenRequest()— patterns that trigger DALL-E
Troubleshooting
- G2 says "Unauthorized": Check G2_TOKEN matches in Worker secrets and Even app
- "Gateway not configured": Verify GATEWAY_URL and GATEWAY_TOKEN secrets are set
- Timeout on short tasks: Gateway may be slow; increase
SHORT_TIMEOUT(max ~25s for CF Workers) - No Telegram delivery: Check TELEGRAM_BOT_TOKEN and TELEGRAM_CHAT_ID secrets
- Gateway returns 404: Ensure
chatCompletions.enabled: truein OpenClaw config + restart
