Say Goodbye to Remote Clutter: The Ultimate BroadLink RM4 pro Smart Hub Review
Published on June 12, 2026 | By Smart Home Tech Hub
Look around your living room. How many remote controls are currently cluttering your coffee table? One for the TV, one for the cable box, one for the air conditioner, and maybe another one for your motorized window blinds. It’s chaotic, confusing, and frankly, a bit outdated.
Enter the BroadLink RM4 pro Universal IR/RF Remote Control—a sleek, pocket-sized gadget designed to replace every single legacy remote in your house and drag your older appliances into the modern smart home era. Let’s dive deep into why this tiny device is an absolute game-changer.
The sleek, minimalist BroadLink RM4 pro replaces up to 255 remotes.
What Exactly is the BroadLink RM4 pro?
The BroadLink RM4 pro is an all-in-one smart automation hub that bridges the gap between old-school standalone electronics and internet-connected smartphones. It features both Infrared (IR) and Radio Frequency (RF) transmitters.
This dual connectivity means it can control traditional line-of-sight devices (like your TV or DVD player) alongside multi-directional radio devices (like RF-controlled automated curtains, ceiling fans, or overhead lighting switches).
💡 IR vs. RF: Quick Definition
IR (Infrared): Needs a direct line of sight to work. Think of standard TV remotes.
RF (Radio Frequency): Can pass through walls and blankets. Used for garage doors, motorized blinds, and specific light switches. The RM4 pro handles both flawlessly!

Standout Features We Love
- Massive Cloud Database: Out of the box, it supports over 50,000+ pre-programmed IR devices including major brands of TVs, air conditioners, set-top boxes, and audio systems.
- Manual Learning Mode: If you have an obscure or vintage piece of gear, don't worry. The RM4 pro features a "code learning" option to program manual buttons easily.
- Voice Control Integration: Fully compatible with Amazon Alexa and Google Home. You can walk into your bedroom and simply say, "Alexa, turn the air conditioner to 72 degrees."
- Smart Routines & Scenes: Program automated workflows via the companion app or IFTTT. For instance, trigger a "Movie Night" scene that turns on the TV, dims the smart lights, and drops the RF-controlled window shades all at once.
