The app works with the tigerexped Remote Control Panel (devices sold separately) via a Bluetooth connection, allowing control of devices in the RV, camper or boat via a mobile device such as a tablet or smartphone. With this app, labels can be adapted, button or on/off functions can be programmed, and button icons and backgrounds can be configured individually. Other functions: voltage monitoring, low voltage warning, and much more. A physical control panel and a control box (remote control panel) are required for this app.
