Pylontech CAN-Bus loses connection to Venus

The Pylontech US2000B CAN-Bus interface shows up under Settings - Service as CAN-Bus-BMS (500Kbit/s) and shows up as device as well.

From time to time (couple hours or 2 weeks) the connection is dropped without any visible reason. After disabling and enabling the CAN-Bus in Settings - Service the Pylontech shows up again .... until next drop.

I'am running Venus Rpi V2.32, a Multiplus II 48/3000 VE.Bus and MPPT VE.Direct in an ESS configuration.

Is there a way to monitor the connection and generate an alert or even better an automatic reconnect.

Thanks Chris
