Music doesn’t have to respect distance.
With HOLOWHAS Ultra, a secure control signal can travel over 4,000 kilometers, allowing a home audio system in New York to be controlled precisely from Los Angeles—in real time, with zero compromise on security or synchronization.
Why HOLOWHAS Ultra Is Built for Long-Distance Control
Unlike consumer-grade smart speakers, HOLOWHAS Ultra is a professional multi-room streaming amplifier designed for:
- Deterministic WebAPI control
- Multi-zone synchronization
- Local network execution without cloud dependency
- Integration with professional automation systems
This makes HOLOWHAS Ultra ideal for secure remote audio control, even across continents.
The Architecture: Zero Trust, Zero Subscription
To achieve remote control without relying on paid cloud services, we built a private encrypted tunnel using Cloudflare Tunnel.
Control Flow Overview
- Control Origin: Mobile phone or laptop in Los Angeles
- Secure Tunnel: Encrypted Zero Trust tunnel (no public IP required)
- Execution Endpoint: Local gateway in New York
- Target Device: HOLOWHAS Ultra amplifier on the home LAN
This ensures:
- End-to-end encryption
- No exposed ports
- Full ownership of credentials and data
Real-Time Execution with HOLOWHAS Ultra WebAPI
HOLOWHAS Ultra exposes a local WebAPI, enabling direct control over:
- Zones and groups
- Volume curves
- Input sources
- Playback actions
Example automation logic:
- Activate selected zones
- Gradually raise volume for comfort
- Trigger a predefined playlist
All commands are executed locally, ensuring perfect timing and audio consistency.
Technology Meets Emotion
This project wasn’t just about remote control—it was about presence.
A command travels thousands of kilometers, not to move data,
but to deliver a moment.
At midnight in New York, music begins to flow through the home—triggered from Los Angeles, carried by fiber, code, and intention.
Why This Matters for OpenAudio Users
- No Subscription Required – No reliance on paid smart-home clouds
- Professional Reliability – Designed for installers and advanced users
- Scalable – From single homes to large multi-zone deployments
- Human-Centered – Technology serving emotion, not replacing it
HOLOWHAS Ultra proves that high-end audio control can be both precise and personal.
