SMA Inverters Data logging

[provr6]

Is it possible to store past data useage onto a usb stick or disc and delete old data from the inverter? If so how do you do it? Thanks

Simple generation data can be extracted from SMA TL inverters using the sma-bluetooth program, a compatible Class 1 Bluetooth Device and a Linux terminal console.
A simple command line script, ran via the cron command, could automatically append generation readings to a text file,
which could be manipulated into an alternative format using a variety of Linux commands.
This could be implemented on a Raspberry Pi, with USB port.
Dont know how to delete historic generation data on SMA Inverters.
