Hello,
I am not very much familiar with interfaces and communication protocols and I am trying to get data from several meters to read it remotely (in a sort of experiment). The meters have an M-Bus interface to a Data-Logger. The Data-Logger has the following interfaces/protocols:
To the meter:
M-Bus
Communication protocols:
Ethernet
RS-232/485
From the above information none of the communication protocols would really help (at least that is what I understand) as I have no option to have a PC onsite - this is why I mentioned accessing the data remotely. The meters are located in the basement. We could get Wi-Fi there though. The vendor of the Data-Logger told me that in any case it could be done via MQTT using a broker. But I do not understand how the data would be sent from the Data-Logger to the Cloud via MQTT using Wi-Fi, as I said I have no option to connect the Data-Logger to a computer in the basement or the building. I would appreciate any guidance please. Perhaps he meant using Raspberry-pi???
