If you need to re-pair your device use the QR code. its in the small booklet inside the box. Do not waste your time on the tutorials listed on their app or website. here's step by step 1) delete the leaf from the app 2) pray to your gods that you have not thrown the box or the booklet away. 3) when found thank the gods and scan the qr code which will give u option to open it on the app 4) follow the in app instructions and u should be connected in no time! no thanks to the devs 👎
