wherein said data-gathering procedure (DGP) comprises a sequence of steps that are cyclically repeated by said accessory device at subsequent sampling periods (TS) to acquire subsequent data-gathering samples (DGS) of grid data (D) based on information specified in a data-gathering file (DGF) stored in said accessory device,

wherein said accessory device is further configured to operate as a client device to implement a data-publishing procedure (DPP), in which said accessory device transmits said grid data (D) to said publishing computerized unit,

wherein said data-publishing procedure (DPP) comprises a sequence of steps that are cyclically repeated by said accessory device at subsequent publishing periods (TP) to transmit a transmission file (TF) to said publishing computerized unit based on information specified in said data-gathering file (DGF) and in a data-publishing file (DPF) stored in said accessory device,

wherein said accessory device is further configured to operate as a client device to implement a data-upload procedure (DUP), in which said accessory device receives upload data (UD) from said interface computerized unit, and

wherein said data-upload procedure (DUP) comprises a sequence of steps that are cyclically repeated by said accessory device at subsequent updating periods (TU) to receive said upload data (UD) from said interface computerized unit.

2. The computerized platform, according to claim 1, wherein said data-gathering procedure (DGP) further comprises:

a step, in which said accessory device sends one or more data-gathering queries (DGQ) to said electronic devices;

a step, in which said accessory device receives data-gathering responses (DGR) from said electronic devices;

a step, in which said accessory device analyses said data-gathering responses (DGR) to check the presence of errors;

a step, in which said accessory device stores data-gathering samples (DGS) of grid data received from the electronic devices for which no errors are found in said data-gathering responses;

a step, in which said accessory device repeats the previous steps for electronic devices for which errors are found in said data-gathering responses; and

/or

a step, in which said accessory device stops the interrogation of the electronic devices for which errors are still found in said data-gathering responses after said previous steps are repeated for a given number of times.

3. The computerized platform, according to claim 2, further comprising a configuration computerized unit capable of communicating with said accessory device and said interface computerized unit through the Internet, said configuration of said accessory device.

4. The computerized platform, according to claim 2, further configured to implement a data logging procedure (DLP), in which said accessory device refines and reorganizes the stored data samples (DGS) of grid data.
