After the firmware upgrade to version 2.72 of the Venues GX it no longer has a stable connection to the RS485-USB serial cable. The Serial cable is connected to the battery and the external smart meter. As a result the ESS stops and starts. No changes have been made to the cable or serial devices. The only change was firmware. If you log into the cat /data/log/dbus-fzsonick-48tl.ttyUSB0/current you can see the unit open the port connect and get data, then disconnect and start the process again.
