Getting meter data remotely

[ksemmler]

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???

There are instructions online to rig a raspberry pi for this sort of thing

THanks. It would be great to know if without raspberry pi there is also a way to access the data. I am actually looking for an alternative to raspberry pi

An Arduino maybe?

I see.
I thought we may need additionally to the dataloger a gateway, that would be easier but I am not sure...

If there is info on the web on how to do it with a Pi then I would look into it. Would make sense.

Any reason why you don't want to use one?

To be honest the complexity. There are also limitations in that building with regards to internet. We would need to install a line there and a repeater (in the basement). It is also not possible to have a PC there (onsite). The monitoring of the data should be therefore, remotely - I cannot be onsite for that.
I think it should be possible via MQTT (using a broker)-> DataLogger would connect to an MQTT broker that's on the internet and upload data...but I am not 100% sure about this.
