Broadlink RM4 pro Smart IR/RF Remote Control Hub with Sensor Cable(2.4GHz Wi-Fi Only)-WiFi IR/RF Blaster for Home Automation, TV, Curtain, Shades Remote, Works with Alexa, Google Assistant, IFTTT

It's a good remote. It has decent range and a good app.The app allows you to learn and send ir commands and also gives you a list of some known devices to work with.The temperature a d humidity readings are accurate enough for me.

it works!the "machine" is excellent in learning a signal and sending out a command signal.however, "setting up" is the difficult part!

Update: I added my TV. My model was on the list and it loaded right up and is working great!Neat product, could use some improvement.I initially purchased this so I could run my IR controlled A/C that is in the Front Room from my Bedroom with my phone. It worked ...but, I had to program the remote on the phone myself cause my AC model wasn't in the database. No big deal, really.The setup tutorial was easy enough and straightforward as long as I didn't try getting ahead of myself. It takes a little time so I'd suggest not diving into it if you're in a hurry.I got the IR blaster With RF for future projects. I'd like to run some plant irrigation drippers, fans and lights for an indoor vegetable and flower garden. I hope it works.Some minor issues that I wish could get looked into is the temperature reads as Celsius and I can't find a way to change it over to Fahrenheit. Also, the Temp+ and Temp- buttons only work as temperature presets and don't change the temp incrementally. That's a little annoying but I can live with it.Overall, a handy piece of kit.

I recently added Home Assistant and I wanted to look to retire my Harmony Hubs so I needed something to fill that gap. It seemed like this Broadlink Remote was the most commonly recommended so I gave it a shot. Setting it up and adding it to Home Assistant was straight forward. Adding commands isnt the most intuitive process but easy enough to learn and repeat. The range is pretty solid and I was able to locate it in a good spot to hit majority of my devices. The only thing I would have like to had was an IR emitter output. It seems like that would be a no brainer to make it easier to hit devices located in a different spot or that aren't possible to get a clean line of sight. Instead I just used a repeater kit that I already had but I dont love using an IR receiver solution, and its extra wires that shouldn't be necessary. Otherwise everything works well and Ive successfully boxed up all of my Harmony Hubs and Elites.

I don't usually write negative reviews, in fact, this is my first. But when faced with such a truly awful product as this, I feel it my duty to warn my fellow humans what frustrations await them when you purchase a Broadlink RM4 Pro.To be fair, I don't know if this device will control IR or RF products or even sync with Alexa, Google Assistant, or IFTTT, as promised. I actually CAN’T know that because I couldn't get past the installation. For a device marketed as a bridge for the smart home market, this device is anything but smart.In fact, its designers had so little disregard for their customers that they thought it acceptable to exclusively REQUIRE 2.4ghz WiFi in a device sold in 2020. That in itself would not be so bad, there are plenty of older, dumber, simpler devices that use this frequency but Broadlink appears to have gone out of their way to ensure 5ghz dual band systems absolutely, positively, cannot be compatible with their product.As evidenced on their support site, which actually recommends that first you disable the 5ghz band for as long as you use their product. Disregarding how unacceptable it is to recommend one stop using a superior technology that was finalized over 11 years ago, the site further recommends that if you cannot disable the band, then you should try to walk far away and see if it’ll connect to the 2.4 band then, or install a temporary router or hotspot with the same SSID/PW. If those methods fail, you should simply get another router. Easy peasy.I actually tried the first two recommendations because I really didn’t want to have to through the trouble of returning… also because I’m an idiot. So after walking down the street with phone, Broadlink, and USB battery bank in hand on 101* day with no results, I setup the mobile hotspot on “phone B”. The issue then arose that, because again it is the year two thousand and twenty, my hotspot was inundated with connection requests from 80+ devices throughout the house wondering where their precious network went. So after shutting off power to the house (yes, really) and manually killing multiple tablets, a couple of UPSs, and a smattering of cell phones, I was finally within the hotspot’s capacity to connect.Only nothing happened. The same stupid app giving the same stupid message. “Could not connect”. 5 days and uncountable hours later, I’m done. I’m sending it back and posting this review. If you have a router made in the last 5 years or have more than 10 devices connected to your network, run away. This device will not work. It is a device marketed to smart home hobbyists, but built for people who have 1 PC hardwired to Facebook for the “news”.I know this review was initially to serve as a warning, but at this point I just don’t care anymore. This was my therapy. If nobody reads this, fine. At least I have bled the poisonous Broadlink experience from my system. Thanks for the refund, Amazon.

Love the function of it. It operates my range hood fan and various home theater equipment with Alexa. I really only use it to turn things on and off so I can't speak to how well it learns and performs a variety of functions. Great solution for my needs for the price and I'm happy with that - when it works! I'm NOT satisfied with range distance. I have had to move it around to find the sweet spot and even still sometimes it's not responsive. I wish I woulda gotten the mini which sounds like has better range.

Very good, not only IR but also RF.
