RM4 Mini IR Universal Remote Control (2.4 GHz Wi-Fi Only), Smart Home Automation Wi-Fi Infrared Blaster for TV, AC, STB Audio, Works with Alexa, Google Home, IFTTT

I have an LG split in my garage/shop, and wanted to be able to pre-heat the space as it's been very cold lately. This unit was incredibly easy to set up, and at least the main functions of the split can be controlled remotely now so I can warm up the shop ahead of using it. Mostly, I needed just on/off. This unit is tiny, and includes a wall-mount plate, so can be tucked-in most anywhere. It does not include a power adapter, but does include a USB-A to micro-USB cable, and can be plugged-in to any adapter you might have lying around. I used an old Amazon Fire charger. Update: I still like this unit, but did find one annoying oddity. If I turn the split on via the app, and then turn it off via the real remote, eventually the split will be turned back on uncommanded. I'm not sure when this happens, but basically the rule is, don't mix use of remotes if you want the state of the split to be known.

Works great with my IR-based space heater. The app is so-so, but works fine for my use case. Placement, especially one that's out of sight, isn't ideal but it works. Ultimately, this was quite easy to get setup and linked to the device. It's also quite small, making it easier to hide. In a dream world this worked natively with Homekit but one can dream.

Impressive little blaster. Pretty much paints the room in IR. I have it connected to the Google Assistant. It would be nice if the repeat rate of holding a button down was a bit faster. Volume adjustment can be a little bit slow. It can be a little bit difficult to learn unsupported devices. I don't understand how there isn't more demand for products like this.

Very easy to set up, and you can control multiple devices at the same time.

Me lo compré para usarlo con Alexa, me daba mucha pereza pararme o buscar el control del A/C, asi que si te da pereza también y tiene alexa o prenderlo con el celular, no te lo pienses.

I've been using an RM mini 3 for years, and purchased an RM mini 4 for another room. Aside from all the awful things the new app does (including collect all kinds of information about you and your network and transmit it to a cloud server) the latest firmware versions have BLOCK THE USE OF THIRD PARTY APPS. I purchased a second one - first one I got - directly from Broadlink's Amazon store was USED. Came in a clear plastic baggie with no packaging or instructions and obviously used. So I returned it and got a second one. My intention was to use this RM mini 4 with AnyMote but it will not work. I did some digging on the Interwebz and it looks like Broadlink is starting to block third party apps from being able to use these devices on newer firmware to force users to use only the Broadlink app.....which is terrible and spies on you. The older RM mini 3 works just fine with anymote so if that's your intent, get an RM mini3 while you can because the new mini 4 on the latest firmware only appears to work with the terrible Chinese-made app loaded with spyware that sends data to a cloud server. What possible reason an app for an IR blaster to constantly send data to a cloud server is beyond me. Returning this garbage! Update: I game the RM4 Pro a shot after finding some info on the interwebz for using these things with Home Assistant and setting it up for local control without Chinese cloud servers. It works but it’s pretty a pretty hacky process and I definitely wouldn’t recommend it to a novice. Even then getting it to learn new codes requires a Linux server and some comfort using command-line tools. It CAN be made to work as a locally controlled device but it’s a lot of work so unless you enjoy that sort of thing I still wouldn’t recommend it even though it ultimately is working for me.

I bought this for a Black & Decker 220 V window unit. I’ve already tried a Sensibo. Neither will toggle all the functions on my AC/heating unit. It’s basically and on off switch for me. Between the Sensibo and this I’ve spent probably $125. My best advice is contact the manufacturer with your model ac number and confirm that it’s fully supported. If they say no, then you’re probably gonna end up with only two commands and that is off and on. Don’t set yourself that would disappointment if you’re looking for these our blasters be sure to chat with the manufacturer unless your model is listed exactly in the description.

This thing is great. If you have a bunch of little remotes for things like lights, candles, fans; use this to control them all from you phone. Or better yet link thw vendor to Alexa and boom voice control. The only downside would be it needs to have line of sight to those items, well or in that same room may work, but hey we all figured that since is just basically a universal remote. I thought it was easy to setup but others not so tech savvy may have to read a bit

We bought a sensibo and one of these to compare. The out-of-box experience with the Sensibo was MUCH better. But after a month of use, these BroadLink devices are far more useful in a so-called "smart home" environment. We were able to leverage HomeBridge, to make our multi-head mini-split heat pumps (three pumps, 6 heads) work as a single unit (or as zoned units) to heat and cool our home. "Siri cool upstairs" or "Siri warm upstairs" and all the units just work. It does take some time to feed the remote settings into the RM4 mini, and it requires a bunch of JSON configuration parameters (so not for the less-technical), but it works and it works well. Also, when you compare the price of other units, I'll take the $35 and the ability to use a local-only connection thank you.

Model: Broadlink RM4 Mini Bought this to replace the function of a remote control. This review is based on the product being used just as a remote control via the App on the phone. (for smart home functions please look at other reviews) For those wondering this is a little USB powered device which works as following: Phone>App>WiFi>Broadlink>Air conditioner. When on sale for $29.99 this is fantastic value. The box it came in was smaller than expected, the entire product was smaller than I thought but I guess it only needs space for just a WiFi antenna and a IR transmitter. Product includes a decently long flat USB cable which is good quality. NO USB power adapter is included, I just use a 5V 1amp Apple USB phone charger and it works fine. It was quite simple to setup following the instructions. Had to go through a process of holding down the reset button on the product for a specific length of time with a toothpick to put the Broadlink RM4 Mini into the correct mode. All of this was quite simple as you go back and forth between the App instructions and included printed instructions. Once up and running it was a easy process to add the Samsung Air Conditioner to the remote App. There were 3 most common options and you can test each before proceeding. AC fully functioned with the 1st option. I set it up across the room initially, but had issues sometimes when you stand between the Broadlink and the AC unit blocking the IR signal. After I moved the Broadlink to below the AC unit on a cabinet and now it works all the time. Also remember to remove the clear plastic which is on the unit as it can also cause issues with the IR signal. App is simple and easy to use. Open the App then tap on the Airconditioner. All the functions are there, more functions are hidden in the "more" section but the most commonly used settings are on the first page and easy to access. It works flawlessly and there is absolutely no delay between tapping the touch screen on your phone and the Airconditioner responding. Works just as well as the original Samsung remote, and even better since you don’t have to point the phone at the AC. It is connected with WiFi so it even works from the next room. Very satisfied with the product. It is small, simple in design and just works. I have read some other reviews saying the process of adding it to a Smart Assistant is a bit more complicated, but I have no experience in that part of the setup. As a simple device which turns your Phone into a AC Remote this product is great. USB powered so consumes very little energy, and probably cheaper in cost than a replacement remote for a Airconditioner. Also never have to worry about changing flat remote batteries thanks to USB power. Extra info: The "Mini" model is IR (Infra-red) only. The "Pro" model is IR and RF (Radio Frequency). RM3 is the older model, and RM4 is the newer model. I think all models have a alternate version which includes a “Temperature & Humidity sensor”. This alternate version may be preferred by some for automatic "Smart Home" function. Our Airconditioner used IR remote so we only needed the "Mini" model. You can tell if your remote is IR by the LED on the top of the remote. If you block the LED with your finger and try turning the AC on the remote should not work.

REALLY GOOD OPTIONS TO AUTOMATE YOUR IR RECIVING DEVICES GREAT COMPATIBILITY ONLY A FEW PRODUCTS ARE MISSING

Crap. Cant connect. Cant reset. Inconsistent. Stay far away. Please take it back

It works very well, it wasn't easy to install
