Read full description

The ERREBIRemotesPro app provides a simple, intuitive and convenient way to copy rolling code and fixed code garage door remote controls. It also offers such additional features as the generation of rolling code remotes without needing the original, the reading of codes already present on a ERREBI remote and the storage of copied codes in a database. Description of the features Remote control copying: Via a step-by-step guide that includes text and images, users can copy various original rolling code or fixed code remote controls. For rolling code remotes, the app provides such important information as the serial number, customization options and a counter for the original remote, which can be changed if required. Automatic, manual and clone copying options are available for rolling codes, as well as a scanner option for certain models. Remote control reading At any time, users can read the information stored on each button of a ERREBI remote control and save it in a database for subsequent use if necessary. Remote control generation By using this app, rolling code remote controls can be generated without needing the original remote. This process can be completed by selecting the manufacturer and configuring the desired settings or by loading up a remote control previously saved in the database. Fixed codes can only be loaded from a database if they have been stored previously, but without selecting the manufacturer or model. Rolling code remote controls that can be generated: Requirements: - The device must be compatible with BLE (Bluetooth Low Energy) - The ERREBI M-BT remote control is needed to function with the app. To activate Bluetooth, hold buttons 2 and 3 on the M-BT remote control until the green LED flashes. - Bluetooth must be activated on the device for the app to work.
