The Solo Mini can copy garage door remote controls and then functions like the original remote. With AM and FM modulations, it can copy all fixed code remotes and most rolling code remotes in the frequency bands from 433.0 MHz to 868.0 MHz. Older low-frequency remotes, also known as quartz remotes, are not compatible. The Solo Mini communicates with smartphones via the Bluetooth LE 4 protocol. Therefore, no internet connection is required for the garage door.
