I am running 6 EG4 batteries in my server rack. One battery (48v) is connected to CERBO CX. Everything worked fine till I migrated from 1.0.20240102beta to latest release "v1.3.20240705".
Version v1.3.20240705 results in: No battery connection at /dev/ttyUSB0
Upgrading to version v1.3.20240615beta results in my battery found. All values seems to be correct.
I wanted to try the Master Branch since I am having multiple batteries.
Version v1.4.20240824dev results in: No battery connection at /dev/ttyUSB0
How to reproduce
Install v1.4.20240824dev via the installer and reboot CERBO CX.
Expected behavior
The battery should immediately be recognized since it was working before.
