BroadLink RM4 pro IR and RF Universal Remote - All in One Hub

In this review of the BroadLink RM4 pro, the bottom line is simple: this is a practical, budget-friendly hub for anyone who wants to centralize infrared and RF devices under one app and voice control ecosystem. It is best for users who have multiple TVs, set-top boxes, air conditioners or RF-controlled curtains and want an affordable way to add smart control and routines. The RM4 pro earns its place by supporting both IR and 433MHz RF devices, offering cloud device libraries plus manual learning, and by adding Alexa and Google Home integration for basic voice control.

Key Features

• IR and RF compatibility: Supports more than 50,000 IR devices and 433MHz RF devices so most TVs, STBs, air conditioners, fans and curtain motors can be controlled from one hub.
• Cloud library with learning: A cloud-updated device database reduces setup time, and manual code learning is available when cloud data is missing.
• BroadLink app control: A dedicated BroadLink app for iOS and Android is used for configuration, scene creation and device management from home or remotely when set up.
• Voice and automation support: Integrates with Alexa, Google Home and IFTTT so common commands and routines can be automated across devices.
• Expandable sensing: Supports an external USB temperature and humidity sensor (sold separately) to surface environmental data in the app.
• FastCon zero configuration: New FastCon devices can be auto-discovered after the first device is added, simplifying expansion of a BroadLink setup.

Who It's For

The RM4 pro is aimed at homeowners and renters who want to add smart control to legacy equipment such as TVs, air conditioners and RF curtain motors without replacing those devices. It suits users who value voice control and scene automation and who are comfortable pairing a single 2.4 GHz Wi-Fi hub to their network and working with a smartphone app.

It is less suitable for users who need Bluetooth support or those who require advanced, guaranteed reliability for complex professional installations. If you rely solely on 5 GHz Wi-Fi, or you want an out-of-the-box perfect app experience with no occasional connectivity troubleshooting, consider other hubs or ecosystems.
