BroadLink RM4mini Smart IR Hub with Sensor Cable – WiFi Remote, Alexa/Google/IFTTT

Meet the BroadLink RM4mini Smart IR Hub with Sensor Cable, a compact Wi‑Fi remote hub designed to simplify how you control entertainment and life appliances. In a busy living room or bedroom, a single hub can replace multiple remotes by learning and storing commands for devices like televisions, set‑top boxes, streaming players, projectors, sound bars, fans, and more. The hub communicates over your Wi‑Fi network, and a companion BroadLink app for iOS or Android lets you reach those controls from anywhere.

Broad compatibility and a growing library

BroadLink supports an extensive IR library—over 50,000 commands across 38 kHz—covering a wide range of devices. The cloud library is continually updated, so newer remotes stay usable without manual updates. If you encounter a device that isn’t matched in the library, you can teach the RM4mini an IR button so that it becomes part of your personal catalog.

• Access a broad, expanding collection of remotes
• Teach new commands for devices not yet in the library

TV, streaming devices, and smart home control

Turn your couch into a command center. Power on your TV, switch inputs, adjust volume, and control playback with voice or the BroadLink app. The RM4mini also acts as a smart AC controller, letting you power on/off, set temperature, adjust fan speed, and switch modes. When you’re away from home, your phone remains a smart remote, ready to send commands as needed.

• Voice control with Alexa or Google Assistant, plus IFTTT actions
• Optional Siri support on iPhone for quick routines

Scenes, automation, and environmental awareness

Designed for real‑world use, the RM4mini can run timers and scenes so you don’t have to fiddle with remotes. It can also display external temperature and humidity in the BroadLink app, letting you trigger climate actions automatically—like turning on the air conditioner when the room warms up or cooling down on hot days.

Note that the RM4mini is an IR hub and does not control RF devices. For Wi‑Fi, ensure your router broadcasts on 2.4 GHz and that your network password uses a reasonable length and characters. The device does not support 5G networks or mesh networking, and it requires a stable 2.4 GHz connection for best results.

Setup, safety, and support

Setup with the BroadLink app is straightforward: connect to a 2.4 GHz network, add the RM4mini, and start teaching or selecting commands from the cloud library. If you run into connectivity issues, friendly support from the seller helps you get back on track quickly.
