Modify a python script to adopt an exist SQLite database -- 2

I have a Rapsberry Pi based unit, which have a connection an IoT system and collect a several data. Likely temperature, switching on/off. I have at RPI a free dev, it looks like running perfect with the sample SQLite database... but on my SQLite db it looks like little bit different. All data in one table, not different. I will use, only display the historical data. The filter of sensors temperature data (which is same name what you can find at 'Label' column ) is stored separately a json file. Job: - can be modify for me in the script the recorded device name, and recorded devices numbers / if it only possible to edit script, that's okey for me. The best if the script can be use the json which determine the stored sensors. - make to chart, the temperature data will be show all in one, - make an automatic saving option, to backup sensors data (the complet SQLite database), one time per month... for example a dropbox folder or Google Drive, and after that a script clear this database.
