No modbus unit ID - carlo gavazzi gridmeter

Carlo gavazzi ET340 is connected but there is no modbus ID.
I see meter firmware version 3.
Every 5 minutes meter connects and disconnects.

I already tried a new color control.

I already reconnected the 3 cables that come from the USB.

Anyone any tips?

Your meter shouldn't disconnect.

As you already have tried a new CCGX, the problem could be the meter itself, the cable from the dongle to the meter, or the USB to serial adapter.

I would try to connect the meter to the Usb converter without extension cable and see if that works, if not, change the Usb to serial converter to a new one, if that doesn't help, make an RMA request for the meter.
