APsystems-EZ1 hangs when trying to implement zero feed-in

[pitticom]

Hello
I'm trying to achieve zero feed-in with the APsystems-EZ1.
https://github.com/AndreBott83/HA_Zero_PV_Grid_Feed_in
It works well at first, but the inverter freezes after a few minutes. Unfortunately it is no longer accessible via the network.
I then have to connect via Bluetooth and activate and deactivate direct mode a few times until the APsystems-EZ1 gets an IP address again.
The query interval has been extended to 30 seconds, but there is no change.
Can anyone understand that?

After how many minutes does it freeze?
In my case, I have a Shelly Pro 3EM. This measures in both directions. No inverter freeze (newest firmware).
