Works Great! Read to setup w/router with same SSID for both 2.4/5 ghz bands. PLUS other Alexa tips!
BroadLink RM4 mini Universal Remote First of all I had trouble setting it up when my Router is set to “Smart Connect” which allows devices to automatically connect to either the 2.4 Ghz or 5 Ghz Wi-Fi bands. To work around this I temporarily disabled “Smart Connect” feature on the router so I could to complete the initial setup of the BroadLink RM4. Once the RM4 was successfully connected to my network after its initial setup - I was able to re-enable “Smart Connect” feature on my Router and then after a router reboot all of my devices were able to automatically connect as before… even the BroadLink RM4. I’ve only experienced this configuration setup issue with 3 smart home “2.4 Ghz Only” devices: 2 BroadLink devices and the other one was Sanoff RF Hub. All my many other devices (Wemo, Wink, August, Amazon – to name a few) that only use the 2.4 Ghz Band worked great with “Smart Connect” enabled on my router so I believe the issue is with the setup software of the two manufacture’s that don’t work - in this case the BroadLink App. I bought this device to issue IR commands with my Amazon Echo voice – Specifically my TCL Roku TV which I can normally control from my Echo via the network commands - except when the TV is set to Energy Saving mode with Fast Start disabled and the TV has been powered off for more than 12 minutes. Then I must first use the IR Remote to power it on. Which is where the BroadLink RM4 comes in. At first I added the remote for my “ROKU TV – IR”– as a TV Remote which is available for my Amazon Echo. The remotes they had on file were flaky on the power button so I created my own and used the Learn Feature to assign to the power button. Next, I added the command to my Amazon Alexa App’s “TV” Routine that I previously created. I just added the device “ROKU TV – IR” to Power On at the top of the TV Routine since it takes a couple seconds longer to power on the TV when fast start is disabled. I left the original power command that is sent via network control in the routine which is further down in the routine after all of the lighting controls. This Alexa “TV” routine worked perfectly when I say, “Computer TV” – it first sends the power button IR Code to the TV then processes the rest of the routine normally. NEXT, I added the eROD Motorized Drapery Rod’s remote to the BroadLink RM4’s App. This time I selected User Defined Remote. I added the three buttons: OPEN, CLOSE, & STOP and it easily learned their IR commands. I was able to control the curtains perfectly with the remote. THEN I added a Scene in the BroadLink App. I chose the General Scene type so that I could control the IR eROD Remote I had just created. I named it “Curtains OPEN” and set it to activate the Open Button on the eROD remote I made. I then created Scenes for both the Close and Stop commands as well. Next I created an Alexa Routine, “Open Curtains” and then added Smart Home activity which controls the Scene “Curtains Open” I created with in the BroadLink App and is published in the Alexa scenes. I also created Alexa Routines, “Close Curtains” & “Stop Curtains” which control there corresponding scenes. I also added the Smart Home activity which controls the Scene “Curtains Close” scene to the Alexa “TV” Routine I talked about earlier. Everything worked as expected. Later on I removed the ROKU TV “TV type remote” and recreated it as a User Defined Remote instead. Then I added & learned the POWER button. Next I added a Scene in the BroadLink app that activates that button. Once that was complete I then added the Smart Home activity which controls the “ROKU TV POWER - IR” scene to the Alexa “TV” Routine I talked about earlier. This method works better for me since when I originally created the “ROKU TV” remote I selected the “TV Remote” type and only assigned IR commands to the power button and that left a remote inside the BroadLink App with only the power button working… the rest of the buttons did not work because I didn’t assign them IR commands. Besides the BroadLink App discovered my TCL ROKU TV via the network and is available if the TV is powered on and so I wanted to get rid of the original “TV Remote” type I created with mostly non-working remote and create one using the “User Defined” type with only one button instead. All in all - I am extremely happy with the BroadLink RM4 IR control capabilities. It’s much better than using Harmony Hub to control devices like the Curtains or other devices that would automatically end activities running when you start another. I have already ordered a second BroadLink RM4 Mini with sensor cable to migrate some devices away from my Harmony Hub that interfere with its primary activities. I think Harmony Hub is stupid to end the active “Watch Movie” activity (Which turns off the Projector and surround sound when the automated sunset closing of the curtains is kicked off. A major issue with Harmony Hub. FYI: Sensor cable – with built in temp & humidity sensors. So far only the current temp is available with Amazon Echo – which is seen as a temperature sensor to the Amazon Echo. Alexa does not currently support the humidity function. However, hourly temp & humidity data readings are available inside the BroadLink App. I named my temperature sensor, “Living Room” inside the BroadLink App. So now I can say, “Computer, What is the Living Room Temperature?” Alexa responds, “The Living Room Temperature is 75.1 degrees!” I also created a Group in the Alexa App named, “Inside” and added the Living Room temperature sensor to that group. So I can also ask, “Computer, What is the Inside Temperature?” I know this review was rather long, but I wanted to add some “how to” information and issue work arounds I did that other users have reported as issues while setting up their BroadLink RM4 Mini to help fill in the gaps for the somewhat lacking instructions on how to setup and configure the device and BroadLink app. Happy Automating and thanks for reading!

Works great controlling IR devices with Alexa.
Works great for IR. I used it with Alexa tu turn on my AC and TV. Could do much more with the RF options, but I haven't used RF yet.

Work very well, takes some work though. has its quirks.
The device is a bit goofy to setup and program. But aside from that, it works well for my Kenmore portable AC unit, a LG in the wall AC unit, and a Dyson Tower fan. Wanted a way to turn on my non smart AC unit remotely, when i leave work so that the place is cool when i arrive home after my long commute. My in the wall unit is 220v and I can't find any simple smart wifi plugs for that. Also, both AC units, will stat off if you cut the power on or off to it, so plug would not work anyways. So, needed a IR blaster device. I also wanted a smart device that i can monitor the indoor temp. The app.....that needs work. For one annoying thing, you can change the temperature readout in the main app settings to F, but that only affects the main "Home" screen. The sub devices, the things you add to control, like my AC units, when open them up to control them, it only shows C. Temp settings for things like AC/Heat is in C as well. The "button" labels in the app, are just oddly named. Like "Wind + / Wind -" for fan speeds etc. I guess it is a China to English thing, the whole app has that kind of feel...but it is not anywhere near as bad as some other apps i have seen. Google Home integration does vary based on the device you program in. You have to play around with what words you say to Google to trigger the correct action. Some things may work, others not. Like i can not seem to figure out how to adjust the Dyson fan speed, Google says it can't do that, or it doesn't under stand, but the same wording works fine for the AC units. "Turn fan speed down" etc. The device is quite tiny and light. Comes with a wall mounting adapter. Its build quality, feels cheapy, but not super cheap like it will break in your hand. Has one LED on the front that lights up when a IR command is given. It is not bright. Overall, decent device, that, if you can manage its quirks, and kinda janky, non-intuitive app and programing steps, it will get the job done to "smartify" IR devices and allow you to control them to some extent via smartphone and remotely.

Good IR blaster for Home Assistant
I wanted to be able to control an IR device with my automation system and z-wave remotes. Once I set this up in the Broadlink app I was able to link it to Home Assistant and used HA to learn the IR codes from the original remote. The device is smaller than I expected, but that's a good thing and makes it less obvious in my living room. The range seems to be about 10-15 feet so keep that in mind when picking a location. I did have some problems connecting it to my wifi due to the length of the password, but I set up a separate 2.4 ghz wireless network for it (something I needed to do anyway) and it connected right away. I'm not using the Broadlink app so I can't comment on how well that works.

Scrivo questa recensione dopo alcuni giorni di utilizzo e di smanettamento con l'app. Io l'ho acquistato con il cavo che ha il sensore di temperatura e umidità perché dovevo programmare delle routine in automatico con il mio vecchio condizionatore che utilizzassero come variabile la temperatura o l'umidità. Pro: - l'RM4 mini è davvero mini, potete metterlo ovunque e non si vedrà. - l'App è davvero completa, potete configurare praticamente ogni elettrodomestico, basta che abbia un telecomando a infrarossi - Integrazione con alexa: naturalmente accende e spegne gli elettrodomestici che installate sull'app, ma ogni scena che create, è comandabile dicendo: "Alexa esegui [nome scena]", davvero molto comodo. Ad es. Scena "Umidifica": 1. Accendi condizionatore 2. Dopo 3 secondi imposta deumidificazione - Le scene create sono utilizzabili con le routine che volete creare, non dovete riscrive la scena per ogni routine. Ad es. Routine "Troppa Umidità": Quando l'umidità raggiunge il 70% allora esegui scena "Umidifica". - Questa cosa nemmeno è menzionata, ma se nella Home dell'App cliccate sul vostro RM4 mini, e nella successiva pagina dove vengono visualizzate Temperatura e Umidità, se cliccate sulle opzioni ("...") -> Property -> Nome bande, e date un nome alla temperatura e all'umidità, ad es. "Temperatura Camera da letto" e "Umidità camera da letto", potete visualizzare questi dati sull'app di Alexa e addirittura se dite "Alexa qual è la "Temperatura camera da letto" vi dice qual è, questa cosa non funziona con l'umidità, ma è comunque una funzione interessante e non documentata. Contro: - Cavo HTS2 (con sensore di umidità e temperatura + alimentazione) un po' troppo corto - Manca la spina USB, perché se non l'avete in casa, dove acquistarla - Nelle Routine che programmate non funzionano le notifiche sul telefono, ma tutto questo può essere ovviato creando delle notifiche ad hoc, ma non dalla sezione Routine, per farlo eseguite questi passi: Nella Home dell'App cliccate sul vostro RM4 mini, nella successiva pagina, dove vengono visualizzate Temperatura e Umidità, cliccate sulle opzioni ("...") -> Property -> Impostazioni di notifica -> Aggiungi notifica. Ora potete aggiungere tutte le notifiche che volete e scatteranno correttamente - La registrazione del prodotto tramite QR code non funziona e quindi il prodotto non può essere registrato. Non che cambi qualcosa, ma per completezza io preferisco sempre registrare tutto quanto Spero che questa recensione sia stata utile a qualcuno

Fungerar felfritt och kan styra ACn både temperatur samt fläkt, ON/OFF, samt även schema med automat styrning. Krånlig installation med app, men fungerade till slut. Mäter temperatur och luftfuktighet i rummet vilket är toppen så man vet om man behöver slå/av på ACn.

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.
