Verdict: Choose the RM4 Pro IR and RF Smart Hub if you already have sensors or prefer a standard setup without bundled accessories. Pick the RM4 Pro Hub with Sensor Cable if you want immediate temperature and humidity data and rely on Siri for voice commands. Both units handle IR and RF control effectively through the BroadLink app.
RM4 Pro IR vs Hub Sensor
Smart home compatibility
Product A supports Alexa, Google Home, and IFTTT. It does not mention Siri. Product B supports Alexa, Google Assistant, IFTTT, and Siri. Siri support allows iPhone users to control devices via voice commands without a separate hub. This gives Product B a slight edge for Apple users who rely on Siri for home automation. Both hubs integrate with IFTTT for custom routines. Google Assistant integration is present in both units. You should check which voice assistant you primarily use before choosing between these two BroadLink hubs.
Included sensors
Product A requires you to purchase the external Temperature and Humidity Sensor USB Cable separately. The product description explicitly states this accessory is not included. Product B comes with the HTS2 Sensor Accessory integrated into the package. This sensor cable provides room temperature and humidity data directly to the app. You can set triggers based on these readings, such as turning on an air conditioner when the temperature rises. If you need environmental monitoring, Product B includes the necessary hardware from the start. Product A requires an additional purchase to achieve the same functionality.
RF control limitations
Both hubs support RF 433MHz fixed code devices like curtain motors and light switches. Neither hub supports RF rolling code control, which is common in garage doors and pellet stoves. Product B explicitly warns that it does not support RF rolling code or learning. It advises checking if your device requires pairing. Product A mentions high compatibility with RF devices but does not detail the rolling code limitation as clearly in its key specs. Both units rely on cloud-updated libraries for IR devices. You must verify your RF devices are fixed code to ensure they work with either hub.
Wi-Fi configuration
Both Product A and Product B require a 2.4 GHz Wi-Fi network for configuration and operation. Neither hub supports 5 GHz Wi-Fi networks. This is a critical detail for users with dual-band routers. You must ensure your router broadcasts a 2.4 GHz signal that the hub can connect to. The power source for Product B is listed as a 5V 1A adapter. Product A does not specify the adapter requirements in its key specs, but both function over Wi-Fi. This shared limitation means installation steps are identical for both units regarding network setup.
Physical dimensions
Product A has specific dimensions listed: 3.35 inches in width, 1.22 inches in height, and 3.35 inches in length. It weighs 5.29 ounces. Product B lists the weight as 5.29 ounces but does not provide width, height, or length in the provided data. Both units are black. The compact size of Product A suggests it can fit in tight spaces. Without exact dimensions for Product B, you cannot compare physical footprint directly. However, the identical weight suggests similar internal hardware density. You may need to check the manual for Product B's exact size if space is a constraint.
Choose the right Broadlink hub for you
iPhone users needing voice control
Product B includes Siri compatibility, allowing you to control devices via iPhone voice commands. This feature is absent from Product A. If you rely on Apple’s ecosystem for hands-free operation, this integration simplifies your routine. You can adjust temperatures or change TV channels using natural speech without opening a separate app.
Users wanting built-in climate data
Product B comes with an integrated temperature and humidity sensor cable. This lets you set triggers based on room conditions, such as turning on the air conditioner when heat rises. Product A requires a separate purchase for this functionality. Having the sensor included makes setup easier and provides immediate environmental feedback in the app.
Budget-focused buyers with existing sensors
Product A does not include the sensor cable, which may suit you if you already own one or do not need climate data. It offers the same core IR and RF control capabilities as Product B. You get Alexa, Google Home, and IFTTT support without paying for accessories you do not plan to use right away.
