Hello Mikko,

I'm stuck with a very simple question, please help. Let's suppose I have a datetime saved in attribute 2.

last_config_date = objects.GXDLMSData('0.0.96.2.1.255')
value = reader.read( last_config_date, 2 )

Value is bytearray(b'\x07\xe9\x03\x05\x03\x10\n\x1d\x00\x80\x00\x00')
value.hex() is '07e9030503100a1d00800000'

What shoud I do do convert it to datetime view like '3.5.2025 16:10:29' as displayed in Director value field?

Best regards, Andrew

Hi,

You can convert byte array to date-time with GXClient.ChangeType method.
Something like this:

print(GXDLMSClient.changeType(value, DataType.DATETIME))
