Download & Compile CSV from Shelly

I need help downloading multiple CSV files from the Shelly online dashboard. I require historical data spanning several months. The files will contain energy consumption, temperature, and humidity data. The goal is to compile all of these individual CSV files into a single comprehensive CSV file. We need to do this for multiple sensors and date ranges so we need an interface to select the sensor and date range to be downloaded and compiled into a singel csv.

Ideal Skills and Experience:
- Proficiency with the Shelly dashboard
- Experience with data compilation
- Ability to handle historical data
- CSV file manipulation expertis
