The script fetches data from the MyEnergi cloud (particular the Zappi Wallbox) and calculates the total daily output in kWh and writes it to a generated .csv file for easy daily tracking.
- 2021-11-28 - Rename the config.py file to config.py.example for better updating
zappi.py - is the main script that should be executed at the end of the day to calculate the total kWh value.
It fetches the hourly status from the MyEnergi Cloud and calculates the total amount from each of the three phases of the Zappi Wallbox and divides the output in Joules by 3.600.000 which leads to the output value in kWh.
config.py - holds the necessary values/constants that are needed to run zappi.py
- user - Insert your MyEnergi Hub Serial number
- password - Insert the corresponding MyEnergi password
- zappi_sno - Insert the serial number of your Zappi Wallbox
- status & zappi_url - Don't change these values
- data_target_path - Change to the path where the .csv files should be stored (daily report value) - e.g. "/opt/_zappi/"
- Clone the repository and edit the config.py.example to suit your needs and save it as 'config.py'
- Open a terminal and
cdinto the directory - Install the python requirements with
pip3 install -r requirements.txt - Run the script with
python3 zappi.py
Execute the zappi.py script in a cron job to be run on a daily basis, e.g. close to midnight, to get the daily total automatically written to the .csv file
At the location defined in the config.py ("data_target_path") you'll find a .csv file in the format "YYYY-MM.csv".
The file will contain the information of the day in the format > Year, Month, Day, timestamp_of_first_charge, Total_kWh
