I'm trying to get telemetry from my Solax hybrid inverter which has a "Pocket WIFI" device installed without the information going across the internet (its my data, its sent unencrypted and stored in a country whose values I do not share, and also giving them the right to meddle with my device at my risk in the portal usage terms).
I have been able to connect to the Solax AP and, by pretending to be the Solax App connected to "local" I can get a dump of raw data as a CSV which I think I will be able to decode. That said, I really don't want to have to set up a dedicated AP client just so I can get this information.
I see that the device is also connected to my LAN, and port 80 is open, but this does not behave like a web server, and throwing the request I made to 22.214.171.124 (ie when connected to the Pocket WIFI AP) did not work.
It also looks like it is sending telemetry unencrypted but not in an immediately recogniseable format to a specific IP address (126.96.36.199, port 2901) that it looks like I can change in the configuration, but I can't find details of the protocol.
Does anyone know how I can access this data without connecting specifically to the Pocket WIFI AP, and without the data going to the cloud?
