Embedded Systems R&D lab, design house, and consulting studio. We take connected products from concept to working prototype — hardware, firmware, and cloud, all under one roof.
Refflion Systems is an Embedded Systems and IoT/IIoT R&D lab, design house, and consulting studio based in Hyderabad, India. Founded by engineers with M.Tech expertise in Embedded Systems and VLSI from JNTUH, we bring together deep hardware knowledge and practical software craft to deliver connected systems that work in the real world.
Over the years, we've designed and shipped dozens of IoT and IIoT proof-of-concepts, prototypes, and production-ready systems for clients across industries. From industrial process automation to community-serving smart devices, our work spans the full product stack: schematics, PCB, firmware, connectivity, cloud, and UI.
We also develop our own products — most notably the AlAleem Systems line of Smart Prayer Times LED Displays, and the upcoming Smart Azan Plug — compact, WiFi-connected devices built on the ESP32 platform for communities worldwide.
Our in-house lab is equipped for embedded hardware design and rapid iteration — from schematic capture and PCB layout to full firmware development and integration testing.
We handle the entire connected product lifecycle: hardware design, MCU firmware, wireless connectivity (WiFi, BLE, LoRa), cloud integration, dashboards, and OTA updates.
From IIoT sensor networks for manufacturing plants to consumer smart home devices, our portfolio spans the full spectrum of connected product applications.
Rooted in one of India's most active technology hubs, with access to world-class manufacturing partners, and experience serving clients globally.
From early-stage ideation to production-ready connected hardware, we cover the full range of Embedded Systems and IoT engineering.
Full-stack connected product development. We design hardware, lay out PCBs, write firmware, set up cloud pipelines, and deliver a complete connected device ready for production.
C/C++ bare-metal and RTOS firmware for ARM Cortex-M, ESP32, ESP8266, AVR, and more. Clean, production-hardened code with OTA update capability built in.
Idea to working prototype in weeks. We validate your concept fast — so you can make informed decisions before committing to production tooling and volume.
Smart sensor networks, machine monitoring, predictive maintenance, SCADA integration. We connect your industrial equipment to the data and insights you need.
Technical advisory for product strategy, architecture review, BOM costing, wireless protocol selection, power optimization, and certification guidance.
Purpose-built connected hardware for community, institutional, and enterprise applications — smart displays, automated audio systems, environmental sensors, gateways.
Beyond client projects, we develop our own line of smart connected devices — purpose-built for communities underserved by mainstream tech.
WiFi-connected LED matrix display for masjids, offices, and organizations. Shows accurate, auto-updated prayer times by location. Supports multiple fiqh calculation methods, Hijri date, jamaat times, and custom messages.
A WiFi wall-plug that plays the Azan automatically at accurate local prayer times — no app required after first-time setup. Built on ESP32-C3 with MAX98357A I2S DAC, powered by an isolated HLK-PM01 SMPS directly from mains.
Our internal reference IoT platform provides a battle-tested foundation for rapid connected product development — covering device provisioning, OTA firmware updates, MQTT telemetry, and cloud dashboard integration.
From microcontroller selection to cloud backend, our team is proficient across the entire connected product engineering toolchain.
We combine the speed of a startup with the discipline of an engineering consultancy — opinionated about quality, pragmatic about timelines.
Deep local roots in India's tech manufacturing ecosystem, combined with experience designing products that meet international certifications and market requirements.
Schematic to cloud dashboard — we own the whole stack. No handoffs between hardware and software teams, just a single team accountable for a working system.
Our rapid prototyping methodology gets you a working device in weeks, not months. We validate concepts early so costly late-stage pivots stay rare.
Years of real-world IoT and IIoT deployments across industrial, consumer, and community applications means we've already solved the problems you're about to encounter.
Have an IoT or IIoT project in mind? Looking for embedded systems consulting, a proof-of-concept, or a production-ready connected device? We'd love to hear from you.
