"✅ ONLINE" : "⚠️ WARNING (Latency)"; const entry = `[${timestamp}] ${deviceId}: ${status}`; logs.unshift(entry); // Add to the top // Keep only last 5 logs if (logs.length > 5) logs.pop(); console.clear(); console.log("=== SMART SECURITY BOX LIVE MONITOR ==="); logs.forEach(log => console.log(log)); console.log("\nNext check in 3 seconds..."); } // Start the simulation setInterval(simulateHeartbeat, 3000); simulateHeartbeat(); ```
