no usage data if no PV-production

[MiLeeH]

Hi.
I found your python-script for the MTEC-API. Thanks for that work so far. All worked as i expected with the DEMO-account.
After placing my credentials into the config.yaml only menu #1-#3 worked ... menu #4 und #5 returned no values.

After doing some more investigation I realized that your script seems to return values only if there was a pv_production for that day / time. For days / hours without pv_production the MTEC_client.py returns no values (even no grid_load) and jumps back to the menu.

Note: My PV-strings are still switched off and I´m waiting for the smart meter to be changed from a oneway to twoway-meter.

Here are two examples from the script-output (generated today):

for menu (4)

Menu:
1: List system topology
2: List station data
3: List device data
4: Usage data (day)
5: Usage data (month)
x: Exit
Please select: 4
(#0) StationId '1xxxxxxxxxxxxxxxx0' : Mxxxxx Lxxxx 1xxxxx
Please select station #: 0
Select no. of days you want to export: 90

or for menu "5"

Menu:
1: List system topology
2: List station data
3: List device data
4: Usage data (day)
5: Usage data (month)
x: Exit
Please select: 5
(#0) StationId '1xxxxxxxxxxxxxxxx0' : Mxxxxx Lxxxx 1xxxxx
Please select station #: 0
Select no. of months you want to export: 3
date, load, pv_production, grid_load, grid_feed, battery_load, battery_feed
2023-09-12, 5.3, 3.4, 0.0, 0.0, 4.9, 3.0
2023-09-17, 10.2, 4.3, 6.0, 0.0, 3.4, 3.5

Summary:
There is no usage data in case of pv_production is switched off (?) or equals zero.
The script reads data only during my "test phases". Looking at my MTEC-App or Web-GUI I can see data for all days since sept 12th (grid_load, SOC)

Kind regards and thanks for your support in advance,
Michael
