After provisioning the motor, how can I verify that the SMS is correctly communicating with the OtoSenseSMS cloud?
You can check that the device is sending data to the cloud by watching the plots of the different sensing modalities collected.
After the end of the provisioning, you can go to the OtoSense SMS web application: search and select the right motor, choose the tab History Plot, then the sub-tab Parameters. Select any parameter and the date and time corresponding to the moment of the installation: you should see the waveform or FFT of the data collected.
