Hello,
after upgrading from 3.54 to 3.55 I’ve lost connection to the 2x ET112 smart meters connected through “1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter”.
I’ve debugged until I reached this point:

qt.dbus.integration: Could not disconnect “org.freedesktop.DBus” to onServiceOwnerChanged(QString,QString,QString) :
dbus-cgwacs selects correctly the adapter but it encounters some error.
the smart meters can be read correctly if the adapter is connected to a PC that runs the Carlo Gavazzi software tools.
I do not know what else to do, stuck for the moment.
Thank you,
George
