Today we're unveiling the Sihi Digital Ecosystem — a unified platform that connects industrial automation, agricultural technology, sports science, music education, health & wellness, and digital commerce through a single electronics core.

The Vision

Sihi Electronics Engineering was founded on a radical premise: that the same Modbus RTU electronics core powering a greenhouse automation system can also drive a martial arts sensor array, a vocal training microphone interface, or a farm management dashboard. One core. Every industry.

What's in the Ecosystem

• 15+ SaaS Products — from AgriBusinessPro to Martial Arts Pro, each sharing one authentication layer, one billing system, and one database backbone.
• Sihi Plant Suite — the industrial & agribusiness control core: Modbus RTU, PLC dashboards, 11 sector lines, 5-level knowledge drill, signed licence.
• Sports Technology — SoccerPro, Fantasy Soccer Pro, FitnessPro, BoardGamesPro, TeamBuildingPro, Martial Arts Pro, Traditional Sports Pro.
• Music & Wellness — MusicVocalTrainingPro for AI-powered vocal coaching, HealthBeautyWellness for holistic wellness.
• Commerce Gateway — ShopPro for subscriptions, courses, premium features, and professional services.

The Architecture

Every product in the ecosystem attaches to a shared production backbone: Cloudflare for edge delivery, Supabase for PostgreSQL + auth + realtime, Railway for API services, and GitHub Actions for CI/CD. When you sign up for one product, you get access to the entire ecosystem — authenticated, billed, and provisioned through a single account.

What's Next

In the coming weeks, we'll be rolling out the first production deployments of AgriBusinessPro, MusicVocalTrainingPro, and SmartFarming — with all other products following in rapid succession. The Community tier is free forever. No credit card required.

At the heart of every Sihi product is a Modbus RTU register map — the same protocol that has powered industrial automation for decades. Here's how we turn register addresses into modern SaaS products.

The Modbus Core

Our electronics core exposes 400+ Modbus registers across 13 sector lines: Greenhouse, Energy, Dryer, Food Processing, Building Materials, Biowaste, Cosmetics, Pharmaceuticals, Agricultural Systems, Power Systems, Martial Arts, Traditional Sports, and Music. Each register is typed (bool, uint16, int16, float32, string) and mapped to a human-readable alias.

The Sihi Platform Layer

A FastAPI service bridges Modbus registers to a PostgreSQL database via Supabase. Every register read/write goes through our RES-API (Register Export Service API) which handles authentication, entitlement checking (5 subscription tiers), and audit logging. The same API powers both industrial PLC dashboards and consumer mobile apps.

From Registers to Dashboards

The Flutter app reads register definitions from a config module (e.g., greenhouse.dart, martial_arts.dart) and generates KPI cards, charts, and automation rules dynamically. This means adding a new industry sector is as simple as writing a new config module — no changes to the platform layer.

Signed Entitlements

Each subscription tier unlocks a specific set of modules and node limits. The entitlement system is cryptographically signed — the licence key contains the subscriber's tier, allowed modules, and expiry date, all signed with our private key. This means offline verification is possible for field-deployed systems.

The Deployment Pipeline

Every code push to main triggers GitHub Actions: flutter analyze → flutter test → flutter build web → Cloudflare Pages deploy. API changes go through Railway's Docker pipeline. The entire stack — from commit to production — takes under 8 minutes.

Martial arts training has always been subjective — coaches judging form by eye, fighters guessing at their power output. With Sihi's sensor-driven approach, we're bringing hard data to the world's oldest combat disciplines.

The Sensor Array

Our martial arts hardware stack includes: piezoelectric force sensors (measuring strike force in Newtons at 1000Hz sampling rate), 9-axis IMU arrays (accelerometer + gyroscope + magnetometer for form tracking), heart rate monitors (optical PPG), and reaction-time photodiode pairs. All connected to the Sihi electronics core via Modbus RTU.

Real-Time Strike Analytics

When a fighter hits a pad or bag, the system captures: peak force (N), contact duration (ms), force curve shape (for technique analysis), velocity at impact, and strike accuracy relative to target center. The dashboard shows these metrics in real-time — coaches can see a fighter's power drop-off within a single round, indicating fatigue onset before it's visible to the eye.

Reaction Drills

The reaction-time system uses RGB LED targets paired with photodiode sensors. The fighter must strike the illuminated target as fast as possible. We measure: reaction time (ms from LED-on to sensor-trigger), accuracy (distance from target center), and consistency (standard deviation across 20+ reps). This data feeds into the AI analytics engine for personalised training recommendations.

Safety Systems

The ring/cage safety I/O includes: mat connectivity sensors (ensuring proper mat coverage), medic-on-site confirmation button, round timer, emergency stop, corner pad status, and overhead camera. These are hardwired safety interlocks — if any sensor reports a fault, the system can alert the referee and halt the session.

From Pad Work to Professional Rings

The same sensor technology scales from a home training setup (single pad + phone app) to a professional ring (16+ sensor nodes, overhead cameras, real-time broadcast overlay). The Modbus architecture means adding more sensors is as simple as wiring them to the next register address — no software changes needed.
