Local Adaptive UI
Real-time device control and adaptive elliptical UI rendered locally, ensuring seamless interaction without cloud delays.
On-Device Behavioral Learning
Built pipelines using reinforcement learning to adapt to user habits, operating fully on-device to maintain data sovereignty.
Edge-Optimized Mobile App
Developed with secure authentication, MQTT-based device control, and native Home Assistant compatibility for remote management.
Universal Device Connectivity
Implemented communication through HA, enabling control of Philips Hue, Google Nest, Ring, and thousands of other ecosystem devices.
Industrial Design & Prototyping
Created 3D design files for the enclosure and collaborated with fabrication vendors to ensure thermal and aesthetic integrity.
Iterative Validation
Continuous validation through demonstrations and stakeholder reviews, ensuring the final product meets complex user requirements.
Multimodal Edge AI Architecture
Our approach decentralizes intelligence by processing high- bandwidth visual and acoustic data directly at the edge. By utilizing quantized models, we reduce latency from seconds to milliseconds, ensuring immediate response times for autonomous navigation and human interaction.
- Local visual feature extraction
- Acoustic signature recognition for occupancy mapping
- Encrypted local-first data persistence
Adaptive Behavioral Learning
EVA doesn't just react; it learns. Our temporal modeling pipeline uses recurrent neural networks (RNNs) to identify patterns in human behavior, allowing the system to predict needs and adjust lighting, climate, and security protocols before they are manually requested.
- Continuous reinforcement learning loops
- Temporal context windows for pattern detection
- Privacy-preserving federated learning updates
STRATEGIC BENEFITS
Full Privacy & Local Processing
Data never leaves the home. Complete local inference ensures absolute privacy and security of your behavioral data.
Ultra-Low Latency
Fast, natural interactions via edge inference. Sub-millisecond response times transform the user experience.
Personalized Automation
Adapts to daily routines via Reinforcement Learning, proactively managing the smart home environment.
Broad Device Compatibility
Integrated seamlessly with virtually all smart devices via Home Assistant's protocol stack.
Compact Intelligent Hardware
Custom PCB and thermal-aware design allow powerful edge computing in an unobtrusive, elegant form factor.
Conclusion
By designing both the software and hardware for EVA, we delivered a complete edge AI assistant that sets a new benchmark for privacy, speed, and personalization in smart home automation. This project demonstrates our ability to deliver integrated, production-ready IoT solutions from PCB design to real-time edge AI that are secure, scalable, and adaptable to the evolving smart home ecosystem.
