Manual
When you open app first time, allow to find new Bluetooth, hit SCAN button, there gonna be your device Mark it as chosen and hit button Back(arrow) then hit the Lamp button and at this Menu hit button (. . .) next to word Disconected, if you will click on this word nothing gonna happen, so click Three dots button and hit Connect, then you can use light change options. It took me 4 hours deleting installing back and force, I’ll give it 3 stars only because it works, but this app really bad
