Review: Great device, slightly tricky setup process - This device essentially replicates any IR remote that you have lying around. By doing this, you can make any IR controlled appliance "smart". As an added bonus, this device can also give you accurate temperature and humidity readouts. You have to use the Broadlink app to connect this device to your wifi network. The broadlink app is a little finicky and doesn't seem to work on some devices. I tried initially on an iphone and it didn't work. When I tried it on an android phone, it instantly recognized the device and I was able to set it up. You can use the Broadlink app to learn IR codes from your existing remote and then blast them out on command through the app. The IR LED seems to be very strong and it always triggers my A/C. The device has not gone offline or dropped Wifi connection in a couple of weeks. It reconnected back to wifi seamlessly after a power outage once. Broadlink has several similar devices and this one seems to be the best value for money. It is also very small and can be discretely hidden behind a cabinet or other furniture. The real trick is to pair this device with a home assistant setup. That way, you can automate a lot of dumb devices around the house.
Review: Nice device - Takes a little bit to setup but works really good once setup. Really works perfect except they had BAD Instructions. I will give you here. (1. Have to download the Broadlink app first. 2. Create Brodlink account. 3. once created and device is configured in the app you can then link the app to Google Home or Alexa. 4. In the app go to voice under settings and select link google home or alexa.) Now all i have to do is say "Hey Google" "Turn on the TV" and boom. Love it!

### ⭐⭐⭐⭐ Use Main Broadlink App
*by L***A on December 28, 2025*

Little manual said use Broadlink Magic Home App or The Broadlink App. I tried the Magic Home as it should work like magic - lost several hours on it and no link up with RM5. Tried the "Broadlink" App and had it up and running in about 30 min. Forget the magic - all smoke and mirrors. Gets nicked one star for the bum Magic App.
