Depending on which VR control box you have, the power source of connectivity to the OPT7 CONNECT app is crucial. Each AURA PRO control box has different firmware software, which sends a signal to the control box using the OPT7 CONNECT APP. See below the different modes depending on VR and specific kits.
If you need help on locating which VR (firmware) you have, prior to naming / editing your control box in the app, the VRXXXX will show up. See LINK more info.
