BroadLink RM4 Pro S Universal RF/IR Remote Control Hub – Smart Home Control Made Simple

Universal IR & RF Remote Control

The BroadLink RM4 Pro S transforms your home into a smarter space by combining both IR (infrared) and RF (radio frequency) remote technologies in one compact hub. With this device, you can control TVs, air conditioners, ceiling fans, motorized shades, lighting, and many RF or IR-enabled devices—all from one app.

Smart Compatibility with Alexa, Google Home, and IFTTT

Enjoy full voice control by linking your RM4 Pro S with Alexa or Google Assistant. Whether you’re turning on the TV, adjusting the fan, or setting the mood lighting, all it takes is a simple voice command. For even more flexibility, integrate it with IFTTT to trigger automation scenarios that match your lifestyle.

Built-in Temperature and Humidity Monitoring

The RM4 Pro S package includes a USB sensor cable that enables real-time monitoring of room temperature and humidity. This feature allows you to set up smart automations—like turning on the AC when the room gets too warm or sending a notification if the humidity is too low.

One App to Control Everything

Using the BroadLink app (iOS and Android), you can manage all connected devices from anywhere in the world. The app allows you to set timers, create scenes, and even learn custom remote commands for maximum control.

DIY Customization and Learning Mode

Have a lesser-known brand device? No problem. With the RM4 Pro S’s learning mode, you can teach it IR or RF commands manually, ensuring compatibility with virtually any remote-controlled device.

USB-Powered with Easy Setup

The included USB cable makes setup a breeze—just plug it into a USB power source, connect to your Wi-Fi network, and begin adding devices. No need for complex wiring or expensive hubs.
