The SMS can be installed on both old and new motors, horizontal or vertical.

Learning Process

Once the installation of the SMS on the motor and the configuration of the device (Wi-Fi Network Motor) are completed, the device starts sending data to OtoSense AI (OtoSense cloud server), which requires a process of learning about the motor’s operation to be able to predict its faults. This process’ duration varies, depending on the motor’s operating conditions, but it usually takes approximately four weeks.
