This broadlink rm4 pro s ir review covers the Broadlink RM4 Pro Hub with Sensor Cable. It is a smart home controller designed to unify your infrared and radio frequency devices. The two specs that define it are its dual IR and RF 433MHz connectivity, plus its integrated temperature and humidity sensor. You connect it via a 2.4 GHz Wi-Fi network and power it with a standard 5V 1A adapter. The included HTS2 sensor cable allows you to monitor room conditions directly through the BroadLink app. This setup lets you automate appliances based on real-time environmental data, bridging the gap between legacy remotes and modern smart home routines.
What stands out
- Supports RF 433MHz fixed code for devices like curtain motors and light switches
- Controls 50,000+ IR devices including TVs, air conditioners, and fans
- Includes HTS2 sensor cable for real-time temperature and humidity monitoring
- Compatible with Alexa, Google Assistant, IFTTT, and Siri for voice control
- Allows custom button programming and learning if cloud data is unavailable
Who it fits
Good fit for
This hub suits you if you have a mix of older RF devices and standard IR appliances. It is ideal for users who want to automate curtain motors, projectors, or light switches that use 433MHz fixed codes. You will also appreciate the built-in sensor if you want to trigger air conditioning or fans based on actual room temperature and humidity. The voice control options make it a solid choice for those already using Alexa, Google Assistant, or IFTTT routines to manage their home environment without needing multiple separate remotes.
Who should skip it
You should look at another option if your RF devices use rolling code technology. The RM4 Pro explicitly does not support RF rolling code or learning, which includes most gate remotes and pellet stoves. It also requires a 2.4 GHz Wi-Fi network and will not connect to 5 GHz bands. If you need to control devices that require pairing before first use, this hub is not compatible. Additionally, infrared signals can be blocked by obstacles, so it may not work well if your appliances are hidden behind furniture or in different rooms.
Verdict: The Broadlink RM4 Pro Hub with Sensor Cable is a practical spec-based solution for managing mixed IR and RF devices with environmental monitoring. It fits well in homes with 2.4 GHz Wi-Fi and non-rolling code RF appliances.
Key specs for Broadlink RM4 Pro
Connectivity: IR, RF 433MHz
This device sends infrared signals and 433MHz radio waves. You can control TVs, air conditioners, and fans via line-of-sight IR. It also handles RF devices like curtain motors and light switches. This dual approach lets you manage both modern smart devices and older legacy appliances. You do not need separate hubs for different signal types. This consolidation reduces clutter on your shelf and simplifies your setup process.
Network Interface: 2.4 GHz Wi-Fi
The hub connects to your home network using only 2.4 GHz Wi-Fi. It does not support 5 GHz bands. You must ensure your router broadcasts on 2.4 GHz for initial setup. This frequency range offers better wall penetration than 5 GHz. It provides reliable connectivity for most homes. Check your router settings to confirm compatibility before purchasing. This ensures stable communication between the app and your devices.
Smart Home Compatibility: Alexa, Google Assistant, IFTTT, Siri
You can control your devices using voice commands through major assistants. Alexa and Google Assistant allow hands-free operation. IFTTT integration enables complex automation routines across different platforms. Siri support is available for iPhone users. This broad compatibility means you can choose your preferred ecosystem. You are not locked into one brand. This flexibility allows you to build a personalized smart home experience.
Power Source: 5V 1A adapter
The unit requires a standard 5V 1A power adapter. It plugs into a wall outlet for continuous operation. This is a common power specification for many electronics. You likely already have a compatible cable or adapter. This ensures the device stays online at all times. Reliable power is essential for maintaining connections and executing scheduled routines. Check your existing adapters to see if you can reuse one.
Physical Design and Build Specs
According to the listing, the Broadlink RM4 Pro Hub Sensor Cable is finished in black. The unit weighs 5.29 ounces. This light weight allows you to place it on a shelf or desk without taking up much space. The compact form factor ensures it does not dominate your living area. You can position it near your TV or air conditioner to maintain a clear line of sight for infrared signals.
The design includes a dedicated HTS2 Sensor Accessory. This component integrates temperature and humidity sensing with a power cable. You connect the sensor cable between the RM4 Pro and the USB adapter like an ordinary cable. This layout keeps the sensor separate from the main hub. It lets you place the sensor in the room where you want accurate readings. The main hub can then sit in a different location for better Wi-Fi connectivity.
Power comes from a 5V 1A adapter. This standard power source makes it easy to plug into any nearby outlet. The device relies on 2.4 GHz Wi-Fi for network access. You must ensure your router supports this band. The physical controls are managed through the BroadLink app. There are no visible buttons on the device itself. This clean exterior reduces clutter while maintaining full remote control functionality.
Setup And Everyday Use Guide
You connect the RM4 Pro using a standard 5V 1A power adapter. The device requires a 2.4 GHz Wi-Fi network for configuration. You cannot use 5 GHz networks. You install the BroadLink app to begin setup. The app guides you through connecting the hub to your network. You also connect the HTS2 sensor cable between the RM4 Pro and the USB adapter. This cable acts as both a power source and a data link. The app displays the temperature and humidity from the sensor’s location. You can set triggers based on these readings. For example, you can program the system to turn on an air conditioner when the temperature rises.
Daily use relies on the app interface. You create timers, scenes, and routines to manage your home. You can schedule devices to turn on at specific times. The app allows you to share the remote control with family members via an invite and join function. You can also program your own buttons if cloud data is unavailable for certain devices.
Voice control is available through Alexa, Google Assistant, and IFTTT. Siri support is also listed for iPhone users. You can use voice commands to turn devices on or off, change TV channels, or adjust AC temperatures. IFTTT integration lets you add more complex automation settings. Remember that IR signals need a clear line of sight. Place the hub close to appliances like TVs or AC units to ensure reliable transmission.
Before You Buy This Hub
This device acts as a bridge for older appliances, not a dedicated thermostat. You already have smart thermostats for HVAC precision. This hub manages TVs, fans, and curtain motors. Check your RF devices carefully. It only supports fixed code at 433MHz. Rolling code systems like gates will not work. Place the unit close to your IR devices. Line of sight is required for reliable signal transmission. Obstacles block infrared signals effectively. You need a 2.4GHz Wi-Fi network. The 5GHz band is not supported. Keep the sensor cable near the room you monitor. The HTS2 sensor reads local temperature and humidity. Share access with family members through the app. Update routines regularly as your needs change. This hub complements your main climate controls. It does not replace them. It adds convenience for non-smart devices. Ensure your voice assistant skills are enabled. IFTTT connections require separate setup. This tool fits into a broader smart home ecosystem.
Check before you buy
- Confirm your RF devices use fixed code at 433MHz.
- Ensure your Wi-Fi network supports 2.4GHz connections.
- Verify line of sight exists for IR devices.
- Check compatibility with Alexa, Google, or Siri.
