Base station and advertising packets of sensors detecting content level

A system, comprising:

• a communication interface configured to establish a network connection with a server and a plurality of remote devices;
• and
• a processor coupled with the communication interface, wherein the processor causes the system to:
• receive a broadcasted advertising packet from each of the plurality of remote devices that each monitor content volume of a container, wherein the received advertising packet comprises:
• a unique identifier of each remote device of the plurality of remote devices;
• a time value or an iteration number;
• and
• measurement data related to volume of content in the container associated with each remote device, wherein each remote device of the plurality of remote devices repeatedly broadcasts the advertising packet to the system;
• determine if the received advertising packet is a duplicate of a previously received data packet by comparing the unique identifier of the remote device and the time value or the iteration number of the broadcasted advertising packet with the unique identifier of the remote device and a previous time value or a previous iteration number of the previously received advertising packet;
• determine if the received advertising packet is not a duplicate of the previously received data packet in response to a determination that the unique identifier of the remote device and the time value or the iteration number of the received advertising packet does not match the unique identifier of the remote device and the previous time value or the previous iteration number of the previously received advertising packet,
• extract the measurement data from the advertising packet;
• and
• send at least a portion of the extracted measurement data via the network connection to the server.
