System and Method for Buffering Sensor Data

A controller comprising:

• a communications interface to communicate with a set of sensors;
• a memory including a buffer to store buffered data;
• wherein the controller is configured to:
• receive, from a server, a first data request;
• in response to the first data request, send to the server the buffered data in the buffer, the buffered data including first sensor data from the sensors in the set;
• obtain, from at least one given sensor in the set, second sensor data detected at the least one given sensor in the set;
• update the buffered data in the buffer to include the second sensor data for the at least one given sensor;
• receive, from the server, a second data request;
• and
• in response to the second data request, send to the server the buffered data in the buffer, the buffered data including the second sensor data for the at least one given sensor in the set and the first sensor data for a remainder of the sensors in the set.
