BroadLink RM4 Pro IR/RF Smart Home Hub – Voice, App & IFTTT Control

Centralize your IR and RF devices with the BroadLink RM4 Pro

The BroadLink RM4 Pro is a compact smart home hub that brings infrared and radio frequency devices into a single, connected ecosystem. By translating both IR and RF signals, it can coordinate gear like TVs, projectors, curtain motors, light switches, and air conditioners from one place. The result is a cleaner control surface, less remote clutter, and the possibility to automate everyday routines without changing your existing devices.

With access to an ever-growing online library and a straightforward learning feature, the RM4 Pro can adapt to new models over time. You can manage everything from the BroadLink app, or extend control with voice assistants and automation services—creating a smoother user experience without demanding you replace your current gear.

Key capabilities

• High compatibility: RF devices at 433MHz (range 430–440MHz) such as curtain/shade motors, projectors, and light switches are supported (note: fixed code, not rolling code).
• Infrared coverage: Supports 50,000+ IR (38kHz) devices, including TV, air conditioner, set-top box, streaming player, amplifier, and sound bar. Online IR library updates keep models current; manual learning is available.

Voice, app, and automation

• Voice control: Works with Alexa and Google Assistant to manage on/off, volume, channels, input switching, and more. Siri on iPhone is supported for quick tasks.
• IFTTT and scenes: Create timers and customized scenes to automate how your IR/RF devices respond to triggers and routines.

Practical setup tips

• IR signals don’t pass through obstacles; place the hub where it has a clear line of sight to your devices.
• 2.4GHz Wi‑Fi only; 5GHz networks and mesh networks are not supported.
• Requires a 5V 1A USB power source (not included) or an equivalent power adapter.

Real-world use cases

Imagine waking up to blinds opening and lights dimming as the room climate adjusts itself. When movie night starts, a single voice command or app tap can power on the TV, switch inputs, and set your preferred scene. If you’re away, you can monitor and control your devices remotely through the app, maintaining comfort and convenience from anywhere.

While BroadLink offers broad compatibility and flexible automation options, some niche or rolling-code devices may not be supported. It’s a good idea to check model compatibility online before purchase to ensure your setup aligns with your needs.
