Universal IR Remote Dongle: The Last Remote You’ll Ever Need

Tired of juggling multiple remotes that always seem to disappear right when you need them? The Universal IR Remote Dongle solves this everyday frustration with a powerful, affordable, and truly open-source solution.This palm-sized ESP32 device functions as both an IR learner and blaster. It learns codes from virtually any existing remote — TV, AC, soundbar, fan, projector, lights — and replays them instantly. No cloud, no subscriptions, no proprietary apps. Just open a browser on your phone or laptop, connect to http://ir-dongle.local/, and control everything from one clean interface.

Why it stands out

• Completely local: Works 100% offline. Your data never leaves your network.

• Easy learning mode: Point any remote at the dongle, press buttons, and they’re saved with custom labels.

• Broad protocol support: Handles NEC, Sony, Samsung, RC5/6, LG, Panasonic, JVC, raw pulses, and Pronto codes.

• Smart home native: Integrates automatically with Home Assistant via ESPHome or MQTT. Create scenes and automations effortlessly.

• Future-ready: Optional 433 MHz RF support for ceiling fans and garage doors. BLE fallback and Meshtastic LoRa compatibility for off-grid scenarios (cabins, RVs, boats).

Built for both makers and everyday users, the dongle offers multiple firmware choices and a responsive web UI with macro support and JSON backup. The sleek 3D-printable case keeps it unobtrusive yet stylish. Affordable at every scale.

A single DIY unit costs just $7.17 using common parts. In volume, the full-featured ESP32-C3 version drops to ~$2.26. Even cheaper USB-only variants can retail for $5–7, undercutting commercial alternatives while offering far more openness and flexibility.The project is fully open hardware (KiCad) and open source. Whether you flash ESPHome for instant Home Assistant integration or customize the Arduino firmware, everything is documented and community-friendly.This isn’t just another IR blaster — it’s a practical step toward reducing e-waste, simplifying smart homes, and giving users real control over their devices.
