Hi Johannas,
It looks like in your first post that your metadata dataframe might have an issue. Can you try the same code but remove the inplace= True from the set_index? Additionally, can you add a 'Type' column to the metadata? You can also output the metadata frame before the push to ensure it is as expected.
This example seemed to work for me:
from seeq import spy
import pandas as pd
import csv
csv_file = pd.read_csv('data_.csv', parse_dates=['Date-Time'], index_col='Date-Time')
metadata = pd.DataFrame({
'Name': ['Temperature', 'RH'],
'Value Unit Of Measure': 'EUR/MW',
'Type':'Signal'
}).set_index('Name', drop=False)
spy.push(data = csv_file, metadata = metadata, workbook='synjen_test004')
