To the customer above: most iPhones (if not all) do not have IR capabilities built in. That’s why it asks you to buy one. If you already have one that plugs into the headphone jack or lightning port ($1-3 on Wish), it should work. I don’t have mine setup yet. But you need some sort of physical IR plug-in to use your phone as a remote. So far I’ve gotten it to turn my tv on and off, and tv volume. Discovered a quick tap of the app icon works as a power button. That’s about it. It has 2 QR codes on the back of the box, one takes you to the app they claim you *need*, one brings you to an English guide (I *think and hope!”. There’s also a QR sticker on the front with an alphanumeric code next to it (printed), and a hand written sticker with the same code as above. Frustrating!
