Broadlink RM4 Mini Smart Remote IR Hub Only 2.4G WiFi, TV/AC Alexa/Google

These devices work well. I was surprised how easy it was to connect this to a TV and get it to work. Sadly it does not work with the XFinity remotes.I use this to control a TV. I have a it connected with a SmartThings hub, Amazon Echo and Third Reality Zigbee Button. When the button is pressed, this device turns on a TV, and opens a Roku app. It allows my dad, who has had several strokes, to be able to turn on and off a TV without having to deal with the complexity of modern remotes.I also have another one connected to a Dyson fan/heater. Mine was purchased before they made smart models, so this allows me to voice control the fan from bed, which is nice.Basically it can be set up with pretty much any device that uses an IR signal.

I bought this to try to control a window A/C unit. It was super super simple to set up, and I had it working in less than 5 minutes. It can control everything on my A/C. I have it in the floor tucked beside a dresser and it has no issues communicating with the A/C across the room. Surprisingly it works better than the actual A/C remote. It integrated with Alexa very easily and continues to work flawlessly. The only down side (which is a given) is that if someone turns the A/C off manually, then the on/off status in the app won’t be correct. Other than that no issues and I’ll be buying a couple more for other devices around the house.

I wanted to be able to control an IR device with my automation system and z-wave remotes. Once I set this up in the Broadlink app I was able to link it to Home Assistant and used HA to learn the IR codes from the original remote. The device is smaller than I expected, but that's a good thing and makes it less obvious in my living room. The range seems to be about 10-15 feet so keep that in mind when picking a location. I did have some problems connecting it to my wifi due to the length of the password, but I set up a separate 2.4 ghz wireless network for it (something I needed to do anyway) and it connected right away. I'm not using the Broadlink app so I can't comment on how well that works.

1st -- the Power cord didn't work. I had to use my own.2nd-- when I scan the QR code on the bottom...the app says this device can not be added with the QR code....so I had to do it manually.3rd -- it would NOT sync with my phone. Spent almost 2 hours...and it would get about 90% there...and just....stop.If you want to exercise your skills at Patience, sure...buy it. If you'd rather keep your hair and relationship with your spouse...who asks you why you're swearing so much, and you snap at him/her...stay away from this thing. It would be easier to buy an IR Blaster and solder it together and connect it up to Linux and download the IR codes manually.I do NOT recommend.

Works as advertised. I set mine up with Home Assistant to control some devices in my son's room. The only hiccup I had was connecting it to wifi. I had to change my router security from WPA3 to WPA2 for it to connect. After connecting, I was able to set it back to WPA3 and it still connects fine after losing power. To connect to Home Assistant, it still requires the device to be added to the Broadlink app and then you have to toggle off the "lock mode". After completing that, you no longer need the app.

Would be a great product if it wasn't designed for 10+ year old Wi-Fi technology. I might get around to actually making it work by setting up a Wi-Fi channel just for it. I know why, you can get a 2.4 GHz radio for a raspberry pi for $4. So they decided to keep the Wi-Fi radio in this very cheap.

I use this with Home Assistant and did not touch the Broadlink app at all, so this review is only about the device itself.TL;DR: Compact device with excellent performance that is perfect for integrating my "dumb" Hi-Fi and TV equipment into Home AssistantPros:- Small and easy to place- Good performance. Immediately sends commands when instructed and can send lots of commands quickly and reliably- It's IR so needs line of sight but has excellent emitters and aiming isn't really a consideration (at least not for my setup)- Holds the WiFi connection reliably and is stableCons:- The power cord is micro-USB. I am sure it is an old design, but everything else I own is USB-C now, and these are an unfortunate throwback- 2.4 GHz only. I suspect that, like its power connector, this is indicative an old design. It works and works well, but if you don't have 2.4 GHz networking, it's a non-starter- It's so lightweight that it's easy to tip over or for the weight of the power cord to pull it down. You may want to mount it rather than using it on a tabletop.

I’m really impressed with the BroadLink RM4 Mini. Setup was straightforward, and it was able to learn and control my IR devices without much effort.It's a great solution for bringing older TVs, air conditioners, and other infrared-controlled devices into a smart home setup. Once configured, it's convenient to control everything from your phone or through voice assistants.The compact size makes it easy to tuck away out of sight, and the IR range has been more than enough for my setup. It has been reliable and responsive in everyday use.Overall, this is an excellent little smart hub that does exactly what it's designed to do. If you're looking to add smart control to infrared devices, this is a great choice.

producto hecho con muy malos materiales que se rompen en apenas unos meses y peor asistencia tecnica, no responden a los mails ni dan señales de vida

The quality the built everything is cool. Looks amazing. But a very powerful internet connection of 2.4GHz is needed. It will not work on Phone’s Hotspot. If one is planning to do so, please do not buy this product.

ホームアシスタントで使ってます。ローカルで成立するのが素晴らしい。最初だけ登録でオンラインつなぎましたが。

07Mar2026First, I want to say that I see some negative reviews that all seem to be from 1-5 years ago.I read through them, after I bought this amazing little device (RM4 Mini) and not one of those things seem to be problematic right now.I'm setting up a Home Assistant (HAOS) "bare metal" (which means, I've installed HAOS on a 3-year old Dell laptop that I have. It has 16GB RAM, an i5-1335U.The very first thing RM4-Mini does upon setup is to update it's firmware. WiFi connection is solid. Not once has it disconnected. Sure, the only downside with this hardware (which is older, yes) is that it doesn't have the ability to connect to 5GHz. Only 2.4GHz. But zero disconnects.As an engineer, I originally wanted something to use as a Universal Remote to replace out old, non-working Logitech Harmony remotes.As I didn't have any information on how to set these up, I engaged Google's Gemini Pro and ChatGPT 5.2 to help me set it up. One thing of note to anyone who wants to use AI to help, I highly recommend to "VERSION LOCK - FAIL CLOSED", listing the current versions of whatever you are using, i.e. HAOS OS: 17.1, Core: 2026.2.3, etc.The reason is, because if you do not version lock the AIs, they will refer to their trained data, which is from 2025 or 2024 and this will NOT work as things change too much.I have found this RM4-Mini to be so much better than I had anticipated. When Scanning the environment, it found all of our TP-Link power outlets (directly, not through the cloud, which is incredible!). It found our Onkyo receiver and made available functions that I didn't even know existed. It found all of our Google Home Assistant displays and even, when permitted, hardware details from our smart phones (let's me see the battery condition).As for some saying that many devices, when operated via the Android app, that may be true, at least at that time, but Broadlink does update their device discovery database.And here's the thing. if you do have a device that is just not listed, you have other options. For one, you can test other devices from that brand and sometimes, even a generic brand might work.But if not, this RM4-Mini has a "Learn" function, which I've had to use in HAOS, since when used within the server, it does not have the ability to gather, automatically, the devices from the web.So you can easily "learn" each button from whatever remote you have.I do recommend this device, but for those who are not afraid to research documentation (or ask the AIs what to do, after locked into the versions of whatever you use).Also, I noticed in the description that it says this uses 2xAAA batteries. That is not true at all. It plugs into a USB cable, which can be from a wall wart. Very easy.Hope this helps.
