Cannot add second Shelly 3EM

[Humpelman]

Hi!
First Shelly 3EM is working fine with the script as an Energy Meter. Thanks for that!
Second Shelly 3EM should add an 3phase PV inverter to the system. Works fine while inserting following command to PowerShell: python3 /data/dbus-shelly-3em-smartmeter_KACO/dbus-shelly-3em-smartmeter.py &
After closing the Powershell window the values are again missing in VRM dashboard.
What I´m doing wrong?
Note: In addition the following script is implemented to add the balcony PV inverter. Its also working fine: dbus-shelly-1pm-and-pm1-Plus-pvinverter-multi-instance
BR, Humpelman

Searched for hours for a solution, wrote to the forum, found the solution within 5 minutes... classic.

nohup python3 /data/dbus-shelly-3em-smartmeter_KACO/dbus-shelly-3em-smartmeter.py &

nohup ensures that the skipt does not hang on powershell and continues to run after it is closed.

Everything works now. Many thanks to Fabian and the community!
