Review: 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.
Review: 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 desertcart 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.
