AttributeError: 'Reg_u64b' object has no attribute 'count'

[braini75]

There seems to be an issue with the class Reg_u64b.

as christoph pointed out in #7 commenting out the whole class seem to help:

I had similar problem when using venus os 3.13 and I solved it by commenting out these lines at Kostal_SmartEnergyMeter.py

#class Reg_u64b(Reg_num):
# def __init__(self, base, *args, scale=1, **kwargs):
# super(Reg_u64b, self).__init__(self, base, *args, **kwargs)
# self.coding = ('>Q', '>4H')
# self.scale = float(self.scale)

I'm not a Python developer, but obviously with the update at Venus OS there is an attribute "count" expected, which is missing at this overriding part of Reg_u64b, so I always got

   File "/opt/victronenergy/dbus-modbus-client/Kostal_SmartEnergyMeter.py", line 46, in device_init
     Reg_u32b(0x001A, '/Ac/Frequency',         1000,  '%.1f Hz'),
   File "/opt/victronenergy/dbus-modbus-client/Kostal_SmartEnergyMeter.py", line 46, in device_init
     Reg_u32b(0x001A, '/Ac/Frequency',         1000,  '%.1f Hz'),
   File "/opt/victronenergy/dbus-modbus-client/Kostal_SmartEnergyMeter.py", line 13, in __init__
     def __init__(self, base, *args, scale=1, **kwargs):
   File "/opt/victronenergy/dbus-modbus-client/register.py", line 59, in __init__
     super().__init__(base, self.count, name, text, write, **kwargs)

A correct implementation of that class should look like:

class Reg_u64b(Reg_num):
    def __init__(self, base, *args, **kwargs):
        super(Reg_u64b, self).__init__(base, 4, *args, **kwargs)
        self.coding = ('>Q', '>4H')
        self.count = 4
        self.scale = float(self.scale)

But I can not see any difference in function. It seems to work well without the re-definition of Reg_u64b.

Should be fixed with #11

I had the same issue and indeed it was fixed by removing the Class Definition (PR #11 )
However I still cannot see my KSEM under "Discovered Devices".

Mylog shows:

Starting background scan
Scanning 192.168.1.0/24
[tcp:192.168.1.7:502:1] Found Energy meter: None KOSTAL_KSEM

Could the "None" mean that i have the known issue regarding deviceId ?
