I have a general question respectively vagueness about "the way" to send my data to my webserver. It is essential that i am independently from the local networks. So my idea is to send the data via a sim to the webserver (In my project i want to send my data to my own webserver).
So what could be the best way? My idea right now is to connect a raspberry pi via a LANcable to my modbus-device and the raspy sends the data via sim (4g) to my websever.
My research revealed that there are tools for the raspy where you can add the 4g extension. Can someone verifiy?
Are there maybe other/better hardware solutions where you can run node-red and send the data via 4g or maybe narrowband IOT? (my modbus-device has only a ethernet-port)
