Astrameter needs restart after Marstek Venus E reboot

Hi,

I am using AstraMeter in a Docker container on a Synology NAS together with a Marstek Venus E (5.12 kWh).

My setup:

• Synology DS224+
• AstraMeter running in Docker
• Marstek Venus E connected via WiFi
• AstraMeter emulating a Shelly Pro 3EM
• Marstek successfully detects the Shelly emulator and works normally

AstraMeter logs show:

Battery detected on Shelly UDP port 1010: 192.168.178.79

Everything works correctly after AstraMeter is started.

Problem

Whenever I reboot the Marstek Venus E, the battery no longer reconnects to the AstraMeter Shelly emulator automatically.

In the Marstek app, the CT meter (Shelly Pro 3EM) appears offline and no data is received.

The only way to restore communication is:

1. Restart AstraMeter container
2. Wait a few seconds
3. Marstek immediately detects the Shelly emulator again

After the AstraMeter restart everything works normally until the next Marstek reboot.

Question

Is this expected behavior?

Does AstraMeter currently require a restart after the Marstek reconnects, or should the Shelly emulator automatically handle reconnections from a rebooted Marstek device?

Has anyone experienced the same issue or found a workaround?

Thanks!
