The smartRV™ controls MODULE are multi-function wireless remote control modules. They can be configured to control more than eight different functions in your RV. Control lights (bulb or LED), jacks, awnings, slides, relays, valves, very long RGB LED light arrays and more. The smartRV mobile app can control multiple smartRVcontrol wireless units at the same time. Download the free smartphone smartRV app, available on iOS App Store and Android Google Play. Each smartRV™ controls unit has over 70 feet of wireless range and cell / WiFi service is not needed for wireless operation. The smartRVcontrols smart RV wireless units also have our smartLOCK™ environmental safety system. This groundbreaking feature will automatically lock all device operation while your RV / Camper is in motion! If you are installing the unit in extreme weather conditions such as outside where weather can be an issue, we recommend an OEM encapsulated module for a 100% waterproof design.
