Unable to select key with esoreader

[stefanvgijsel]

Hi there,
I am working on a Python code in Pycharm. With this code, I run EnergyPlus for a certain IDF. Everything works, except I want to be able to select the correct zones from the eplusout.eso file. This is my code right now:

import esoreader
import pandas as pd

PATH_TO_ESO = r'/Users/stefan/Documents/Studie/TU:e/Master/Graduation/Python/Output files/EP files/eplusout.eso'
dd, data = esoreader.read(PATH_TO_ESO)

# The variables you're interested in
variables = ['Zone Air Temperature', 'Zone Mean Radiant Temperature', 'Site Outdoor Air Drybulb Temperature', 'Electricity']

output_data = {}
for variable in variables:
    found_variables = dd.find_variable(variable)
    if not found_variables:  # if the list is empty, skip this iteration
        print(f"{variable} not found.")
        continue
    frequency, key, var = found_variables[0]
    idx = dd.index[frequency, key, var]
    time_series = data[idx]
    output_data[variable] = time_series

# Convert the data to a DataFrame
eso_df = pd.DataFrame(output_data)


# Rename the columns
eso_df = eso_df.rename(columns={
    'Zone Air Temperature': 'Zone Air Temperature [C]',
    'Zone Mean Radiant Temperature': 'Zone Mean Radiant Temperature [C]',
    'Site Outdoor Air Drybulb Temperature': 'Site Outdoor Air Drybulb Temperature [C]',
    'Electricity': 'Electricity Heating [kWh]'
})

# Convert the unit of Electricity (Joules to kWh)
eso_df['Electricity Heating [kWh]'] = eso_df['Electricity Heating [kWh]'] / (3600 * 1000)


# Print the DataFrame
print(eso_df)

eso_df.to_csv('/Users/stefan/Documents/Studie/TU:e/Master/Graduation/Python/Test/eso_data.csv')

For the Zone Air Temperature and Zone Mean Radiant Temperature, 2 zones are outputted from energyplus. I am only interested in Zone 1. They are called the following in the eplusout.eso library:

• 499,1,APARTMENT:ZONE1,Zone Air Temperature [C] !Hourly,ON
• 289,1,APARTMENT:ZONE1,Zone Mean Radiant Temperature [C] !Hourly,ON

I guess, I should use the esoreader to select the right key, but I don't know how. Can anyone help me out?
