The StellarMate Mobile App requires a QR Code (on the back of StellarMate Controller) in order to operate the StellarMate Controller. NO registration is required to use the StellarMate Controller if you intend to use it directly via Web or via Ekos client on Mac/PC/Linux. This step is only required if you want to use the StellarMate Mobile App. You can continue to use StellarMate as is, including accessing the Web Manager and VNC:
