Who it fits
Good fit for
This hub suits users with mixed legacy devices needing IR and RF control. It is ideal for those who want to automate fans, blinds, or AC units using the included sensor data. The setup works well for households already using Alexa or Google Home for basic voice commands. You will benefit from the app-based routines if you want to trigger actions based on room conditions. It fits neatly into setups requiring a central universal remote without complex wiring.
Who should skip it
You should look elsewhere if your home network relies on 5GHz Wi-Fi or mesh systems, as this device only supports 2.4GHz connections. It is not suitable if you need rolling code support for security gates or garage doors, as it only handles fixed codes. Users expecting native humidity and temperature routines in Alexa or Google Home will be disappointed, as these platforms do not currently support those specific automations for this device. You must also provide your own 5V 1A USB power adapter.
Verdict: The BroadLink RM4 Pro S is a practical universal remote for users with 2.4GHz Wi-Fi and fixed-code RF devices. It offers solid basic automation through its app, though voice platform support for sensor data is limited.
BroadLink RM4 Pro Key Specs
Connectivity: IR, RF 433MHz
This device handles both infrared signals and 433MHz radio frequency commands. You can use it to control traditional televisions and air conditioners via IR, while also operating ceiling fans and electric blinds through RF. This dual capability allows you to replace multiple dedicated remotes with one central hub, simplifying your smart home setup for mixed legacy and RF devices.
Network Interface: 2.4GHz Wi-Fi
The unit connects exclusively to 2.4GHz Wi-Fi networks. You must ensure your home router broadcasts on this band, as the device does not support 5GHz or mesh networks. This limitation means you need a compatible network environment for reliable operation. Check your router settings to confirm the correct band is active before attempting installation or pairing.
Smart Home Compatibility: Alexa, Google Home, IFTTT, Siri
You can integrate this hub with major voice assistants and automation platforms. This allows for hands-free control using voice commands for tasks like turning on a TV or adjusting volume. It also supports complex routines through IFTTT and Siri shortcuts, giving you flexibility to link this remote with other smart devices for coordinated home actions.
Power Source: 5V 1A USB adapter
The device requires a standard 5-volt, 1-amp USB power source to operate. The package does not include this adapter, so you must provide your own. This is a common power specification for small electronics, meaning you can likely use a spare phone charger or a USB port on your computer to keep the hub powered continuously.
Design and Build Quality
The BroadLink RM4 Pro S is a compact universal remote hub. According to the listing, the unit measures 3.35 inches in width, 3.35 inches in length, and 1.22 inches in height. This small footprint allows you to place it on a shelf or mount it discreetly in a living room. The device is finished in black, which helps it blend into most home decor schemes without drawing attention. You do not need a large surface area for it to function effectively.
Power comes from a 5V 1A USB adapter, which is not included in the package. You will need to provide your own compatible power source to keep the hub running. The listing notes that the device requires a secured 2.4GHz Wi-Fi network. It does not support 5GHz bands or mesh networks. This means you must connect it to a standard home Wi-Fi router that broadcasts on the 2.4GHz frequency. Ensure your network settings allow this before installation.
The design includes a slot for a USB sensor cable. This cable allows the hub to detect real-time temperature and humidity in the room. You can use these readings to automate other devices, such as turning on a humidifier when air is dry. The physical layout is simple, with no visible buttons or displays mentioned in the specs. Control is handled entirely through the BroadLink App or voice commands via Alexa, Google Home, or Siri. This minimalist approach reduces clutter on your entertainment center.
Setup And Everyday Use Guide
You begin setup by connecting the BroadLink RM4 Pro to a power source. The listing specifies that it requires a 5V 1A USB adapter, which is not included in the package. You plug the unit into a wall outlet or USB port to provide the necessary power for operation. Next, you connect the device to your home network. The RM4 Pro requires a secured 2.4GHz Wi-Fi connection. It does not support 5GHz networks or mesh network configurations, so you must ensure your router broadcasts a compatible signal. Once connected, you use the BroadLink App to configure the device. You can link your account to Alexa, Google Home, or IFTTT to enable voice control. This integration allows you to issue hands-free commands for devices like televisions or volume adjustments. For daily use, the unit acts as a central hub for your infrared and RF devices. You can create timers, scenes, and routines within the app. The included USB sensor cable detects real-time temperature and humidity, allowing you to automate actions such as turning on a humidifier when levels drop. Note that while the app supports these routines, Alexa and Google Home currently do not support humidity or temperature routines directly. The device also supports Siri shortcuts via IFTTT. You control your entertainment gear and appliances through a single interface, consolidating multiple remotes into one easy-to-use system. This setup ensures you manage your home environment efficiently without needing separate controllers for each device.
Before You Buy This Hub
You need a separate 5V 1A USB adapter, as the package does not include one. Ensure your home network provides a stable 2.4GHz Wi-Fi connection, since this device does not support 5GHz or mesh networks. Check that your smart home ecosystem includes Alexa, Google Home, or IFTTT for voice control and automation. Note that while the BroadLink app supports humidity routines, Alexa and Google Home currently do not support temperature or humidity automations directly. The included sensor cable allows real-time detection of room conditions, but you must configure these routines within the BroadLink app itself. This hub fits well alongside smart thermostats by controlling non-thermostat devices like fans, blinds, and ceiling lights. It acts as a central bridge for legacy IR and RF devices. You should verify that your RF devices use fixed codes, as rolling codes are not supported. This setup helps you consolidate multiple remotes into one app, streamlining your daily interactions with home entertainment and climate control accessories.
Check before you buy
- Confirm you have a 5V 1A USB adapter for power.
- Ensure your Wi-Fi network is 2.4GHz and not 5GHz.
- Check that your RF devices use fixed codes, not rolling codes.
- Verify your voice assistant supports BroadLink skills for setup.
