Movable barrier anomaly detection and data backfilling

A barrier operator monitoring system, comprising:

• a cloud processing platform;
• and
• a barrier operator system comprising:
• a movable barrier;
• one or more sensors configured to measure data regarding the barrier operator system;
• and
• a barrier operator configured to:
• move the movable barrier;
• detect a loss of a data connection between the barrier operator and the cloud processing platform;
• collect the measured data from the one or more sensors during the loss of the data connection;
• perform wavelet transformation on the measured data;
• store one or more coefficients of the wavelet transformation;
• and
• transmit, upon restoration of the data connection, the one or more coefficients;
• wherein the cloud processing platform is configured to:
• receive the one or more coefficients;
• reconstruct a representation of the measured data based on the one or more coefficients;
• compare the representation of the measured data to model data;
• detect an anomaly in the barrier operator system based on the comparison;
• and
• transmit a notification from the cloud processing platform to a user device, the notification identifying the detected anomaly.
