BroadLink 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.

Highly recommended when paired with my Alexa. Setup was easy and straight forward.

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

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.

Very easy to set up and worked perfectly with my Ac.I could automate the task as per schedule
