RM4 Mini Smart Remote IR Hub Only 2.4G WiFi, TV/AC Alexa/Google | Infrared Universal Remote Replacement,38KHz IR Blaster Smart Home Hub for Automation, Voice Control and Smart Timer

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 Assistant Pros: - 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 stable Cons: - 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.

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.

Great little IR blaster and it shows up easily in Home Assistant. I wish it had a few more instructions, but it's easy enough to figure out

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.

I will edit this review if Broadlink provides fixes. First, only one Brand in their database for air conditioners is absurd. If you have a Frigidaire, you may be okay, but I wouldn't count on it. You have the remite "Learn" option if you actually have the remote. I had a cheap IR blaster before that cintrolled this same air conditioner without having a remote. I could turn it on and off, change modes, fan speeds, temperatures, etc. It is also a heater, and I could set this. This Broadlink RM4 mini can only turn the unit on/off from Google Home. No other operations. Even from Broadlink's own app, the buttons only learn the state of the unit when the button is programmed. For instance, if the AC is at 65 when you program the Temp+ button, it will treat this as a preset fixed to 66. Regardless of where the AC is set, pressing Temp+ will set it to 66. The same goes for Temp-. To set fan speeds, you have to make sure that function (typically a toggle) is set below what you want the button to be learned to. If your remote goes from Auto --> low --> medium --> high, the back to auto, you need to start with it on Auto to have it learn "Speed 1." Again, theae are no limitations of the air conditioner because I have had full control of the same unit with a cheap IR at half the price of this one.

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.

It says works with Alexa but it does not. I’ve set up many devices with Alexa and this one doesn’t work with Alexa.

I bought to control an Haier A/C unit, through the Google home app. Set up is simple. Download BroadLink app. Connect device to your home 2.4Ghz Wi-Fi. From there, you can look up devices, scan QR codes, and if you do not see your model, other customers posted operational remotes for various models, tag were not already in the BroadLink library. From there, you select the model, device remote show, select learn button, select the button you wish to program on your phone, it prompts you to learn it, point IR remote at device with tangible remote, and hit learn, then the button. It will show success and ask you to press the phone button to verify. If done proper, the buttoned learned, will work. Move in to the next button, then to the next device. I have a wife projector, not compatible with Google home. BroadLink bridged it, so my phone can ask Google to turn item on, asking BroadLink. It basically activated device to perform a shortcut, saved by BroadLink. It is a small round device, easily concealable, with a endless library of appliances. Siri performs shortcut directly from iOS, seamless integration. Love it. **Photo of device next to a standard key fob. Very discrete.

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.

07Mar2026 First, 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.

Con questo ir si comanda praticamente tutto. Basta che si copia il segnele che si vuole inviare ed il gioco è fatto. Si puo configurare con alexa per avere servizi con comandi vocali. Qualità costruttiva buona.
