One remote for 80,000+ devices

The BroadLink RM4 Pro consolidates infrared and 433 MHz radio-frequency control into a single black unit measuring 4.1 by 3.5 by 1.4 inches. It targets households that want to manage televisions, air-conditioners, curtains, fans and similar appliances from one place without juggling multiple handsets.

WiFi 2.4 GHz connectivity and app control

The device connects to a 2.4 GHz WiFi 2 network and draws power from a DC 5 V source, so placement only requires a nearby USB socket. Through the Broadlink app users can operate every paired IR or RF appliance from anywhere with an internet connection, and an optional external temperature-humidity sensor adds room-environment monitoring.

Replaces a drawer full of remotes

Owners of the earlier RM Pro gain three-times stronger 433 MHz emission and the new sensor support, making the upgrade worthwhile when range or environmental data were limiting factors. Households that rely solely on Bluetooth or 5 GHz WiFi devices will not benefit, because the RM4 Pro communicates exclusively over IR, 433 MHz RF and 2.4 GHz WiFi.
