    • The first device (D1) for monitoring products (P), is configured to repeatedly carry out a sensing step using the sensor; and, for each of the sensing steps, to store in its storage unit (M 1)
      - sensing data (sd) indicative of a result of the respective sensing;
      - time data (td) indicative of an associated sensing time (t); and
      - status data (st) indicative of a transmission status.
      The first device (D1) is furthermore configured to, repeatedly, prepare and subsequently conduct a transmission via a first communication network in which a first data set (DS1) is transmitted which comprises transmission ID data (TID) identifying the respective transmission; first ID data (ID) identifying the first device (D1); sensing data (sd) the respective associated time data (td).
      The first device (D1) is furthermore configured to link the transmission ID data (TID) to the respective transmitted sensing data (sd), and to receive acknowledgement data sets (ACK) which comprise transmission ID data (TID) identifying one of the transmissions conducted by the first device (D1). And it is configured
      - to set the transmission status of sensing data (sd) to "ready" upon storing the respective sensing data (sd); and
      - to set the transmission status of sensing data to "acknowledged" upon receiving an acknowledgement data set (ACK) which comprises transmission ID data (TID) linked to the respective sensing data (sd).
