Works as advertised, I set this up to provide control of an older tv and stereo in Home Assistant using MQTT so i would not need to rely on the cloud.

Did not work on any of my 3 A/C units. Was no ise to me.

This LinknLink Wifi based universal remote is a solid little device used to enable automation or wifi-remote capabilities for IR in a single room. The device plugs in to any standard USB port for power, and with the app (via store or side-load) enables the owner to emulate most device IR remotes via an app on the phone. With added firmware (in beta, from the developer website) one can set this device up to use MQTT and connect to Home Assistant, or any MQTT based system, to enable output automation.For HA: I will note that the process for enabling HA/MQTT this is not exactly straight forward. One first needs to go to the manufacturers site to download the firmware used to enable MQTT functionality. It's not shipped with this functionality out of box. You want to do this as step 1, as anything learned prior to that is lost during the flashing process. There is also a limitation that the device will only handle locally emulating about 8 remotes. The software says "one of each type: TV, DVD, VCR, Fan/AC, etc", but in reality, you can manually program and rename any of the devices, so it's not quite that limited.The programing model database they have available is slightly problematic. The app lists several manufacturers and often has 2 or 3 generic versions for remotes of the given manufacturer and device type. But getting to them and testing them is not intuitive until you've done it once or twice. Testing them one at a time can lead to picking the wrong one, or none actually working, at which point it drops into the standard "learning mode" for the category. Sometimes you want to do that though, as jumping directly to self-learn doesn't always enable all the keys a remote for the device of that type should have. (eg. For a TV remote, it may not expose play/pause, even for a smart TV. Where if you choose a smart TV and "test" a version of it, it them presents them for learning.) This is an app limitation, which I hope they correct in the future by allowing users to choose the device style/button layout for the remote being learned.The training mode is rather simple. The app places the puck in training mode, and presents a remote with greyed buttons. You then press the button in the app, and when prompted press the button on the remote while aimed at the puck. It will then give you a button in the app to press to test playback to verify the code works with the given device. Once learned, the button on the virtual remote is enabled, and a sub-device button is created in the MQTT configuration output. Unfortunately there does not appear to be a way to initiate training mode from HA at this point. Something I hope they also consider.For the HA backend: Each remote shows up as a scene switch, with multiple sub-device buttons. Pressing said button initiates an MQTT request to the device to initiate the pulse. HA sees this as an output only device, and there is no way to watch for input IR that I can see. For this to work properly, the device must remain plugged in, connected via wifi to the MQTT server, and be close enough that the IR burst is visible to the device(s) in question (about 4m). The device does NOT need to have full internet access, so a localized IOT LAN is fine. The app used to program the IR device prefers to have internet access when setting up the device, but after a timeout delay it does allow program mode without it. The manufacturer has various versions of firmware to download for their devices, and copies of the apps in APK format for android to enable side-load if desired. This is great, since it means you can archive these items for local use, making the item not rendered useless in the event the manufacturers servers go away.

I've tried several of these IR blasters but unfortunately most of the "cheaper" ones dont actually work in Home Assistant. This one has a specific firmware and uses MQTT and is very fast because of that. It has limited device support so check their site. I got it for a Fujitsu HVAC that works great, and since purchasing they've already upated the firmware and now it supports a "dumb" LED wetbar shelf that uses standard IR lighting I expect are pretty generic. So that just let's me control it as part of an automation now in my mancave. LOVE IT! for the price, I wouldn't get anything else anymore...

WPA2 WiFi passwords can be up to 63 characters in length, but the app for some reason has a 36-character limit on the password field (developer typo, maybe?). Because of this, it's impossible to set up the device if you have a secure WiFi setup. If they ever fix the bug, I'd love to try out the product. Until then, I can't recommend it.

Waardeloze service; eerste levering krijg ik een volledig ander artikel toegestuurd. Na veel moeite om het pakketje terug te sturen, kreeg ik de het na de tweede keer bestellen EXACT het zelfde verkeerde artikel…. Als dit niet normaal opgelost kan worden zal ik iedereen afraden om gebruik te maken van amazon…

Está bien para el precio

exelente para usar el asistente y dejar a un lado los controles remotos

Our Minisplits have an in room remote with minimal programability. The wifi component you can purchase is expensive and still has minimal programability. Connected to this little IR unit and now can control on Iphone when away or using Alexa. Easy to setup and allows us to manage/control while elsewhere.. Great product!

Works well after a confusing initial setup

Finally got a control gadget that actually works with my air Conditioner being an older unit other similar remote automation units just didn't sync.This works allowing smart control of temp,fan and swing of airflow. Phone app works from anywhere as does Alexa and Google Ai voice contril

This business claims that it works with home assistant... Nope!I mean maybe, but it took me quite a lot of investigating to determine that the amount of coding and techno magic I'd need to accomplish is insane.
