2026 verdict
Step up to RF or stay with infrared? For TVs, air conditioners and other IR gear, the BroadLink RM4 Mini is the smarter buy of these two BroadLink blasters, cheaper and better reviewed.
It shares the same core with the BroadLink RM4 Pro: 2.4 GHz Wi-Fi, a universal remote with smart learning, Alexa, Google Home and Home Assistant support and a 1-year warranty, with no Apple Home, SmartThings or Matter on either. The one thing the BroadLink RM4 Pro adds is RF, so it can also learn radio remotes for blinds, fans, fireplaces and RF outlets, in a wider 84.4 mm body against 48 mm. Its owners warn that RF only works reliably with common fixed-code 433MHz devices. Buy the BroadLink RM4 Mini if everything you control uses infrared, and the BroadLink RM4 Pro if a device in your home runs on a radio remote.

What the differences mean
RF control
The BroadLink RM4 Pro learns radio remotes as well as infrared ones, which is what blinds, ceiling fans, gas fireplaces and RF outlets often use. The BroadLink RM4 Mini is infrared only. Pro owners stress checking a device's frequency first, since rolling-code remotes will not copy.
Size
The BroadLink RM4 Mini is a 48 mm cube that disappears on a shelf or a wall plate. The BroadLink RM4 Pro is a flatter 84.4 mm square, still small enough to hide behind a TV.
Everything else
Wi-Fi, smart learning, the BroadLink app, Alexa, Google Home and Home Assistant support and the warranty are the same on both. If nothing in the house uses RF, the two do the same job.
Which one to buy if
- every device you want to control uses an infrared remote
The BroadLink RM4 Mini does the same IR job for less money.
- you have RF blinds, fans or outlets
Only the BroadLink RM4 Pro can learn and send radio commands.
- you are replacing a Logitech Harmony
RM4 Pro owners chose it for handling IR and RF devices, each one switched independently.
- the blaster has to be as discreet as possible
The BroadLink RM4 Mini is the smaller of the two and comes with a wall-mount plate.

What owners say
Owners of both BroadLink blasters praise the same things: quick setup from the brand library, a learning mode that copies unsupported remotes, and Alexa or Google voice commands that fire almost instantly. Both groups also warn that the hub is 2.4 GHz Wi-Fi only, leans on BroadLink's cloud by default and makes voice channel changing fiddly. BroadLink RM4 Mini owners single out its wide IR reach, covering a whole room from almost any placement, and complain that no power adapter comes in the box. BroadLink RM4 Pro owners talk about running IR and RF in one box, cheaper than a Logitech Harmony, with fully local control in Home Assistant, and their main complaint is RF devices with rolling or proprietary codes that it cannot copy.
Upgrading from the BroadLink RM4 Mini?
Moving from the BroadLink RM4 Mini to the BroadLink RM4 Pro adds one capability: RF. You keep the same app, smart learning, Wi-Fi and Alexa, Google Home and Home Assistant support. It is worth it only if you have a radio remote to replace, and only if that device uses a common fixed-code 433MHz signal, which owners recommend checking before buying. If all your gear is infrared, the Mini already does everything the Pro would.
