Hi!

I tried to connect 2 dlms meters using Gurux.DLMS.Python. I can read the first meter but got "Service not allowed. Operation not possible" error message on the second one. Is there anything I could do about it?
Thank you in advance.

Hi, is there example on how to read two meters simultaneously with arduino? I'm using rs485 to ttl module. This is their client.init.
Client.init(true, 1, 145, DLMS_AUTHENTICATION_LOW, "11111111", DLMS_INTERFACE_TYPE_HDLC);
Client.init(true, 1, 146, DLMS_AUTHENTICATION_LOW, "11111111", DLMS_INTERFACE_TYPE_HDLC);
I searched on forum but I didn't find example how to read them all at once. Thanks.

Hello! How does the shift time clock method work? When i try it to use like clock.shiftTime(reader.client, 10) it appears that i can't connect to clock object - reader.read(clock, 2), for example, returns None. Am i doing something wrong?
Thanks for help!

Hello! What methods in GXDLMSClock object are responsible for hard and soft time correction?
Thanks for help!

Hello! I can't understand how to write last day and second last day in date time format. Is it something like GXDateTime("FE/FF/FFFF 00:00:00") or not?
Thanks for help!

I attempted to read my meter using Python, but the outcome was a "disconnect request" like this:

Hello! I am trying to read object - end of biiling period. And this line of code reader.read(end_billing_period, 2) throws an exception: gurux_dlms.GXDLMSException.GXDLMSException: Access Error : Device reports a undefined object.
And it's very strange because GXDLMSDirector can read this object. It doesn't throw an error. What are the reasons of failing in code?
Thanks a lot for help!

hello,

I'm trying to connect Arduino to Secure Premier 300 using GuruxDLMS Arduino library. I was successful to compile and flash the program. But, I got received bytes : 0, data send failed, trying to resend 3 times and com_initializeConnection failed 252.

I have set parameters in Client.init() in void setup() following device configuration in Gurux DLMS Director (I was successful connect and read data to the meter using DLMS Director with this config). Is there anything I missed?

Thank you.

I have been trying to get previous month's data of my three phase smart meter and I do not understand 1.8.1*X obis code. Please help me how to get the X value.

Thank you.

Hi Mikko,

I can establish communication with single phase meter in all associations and PC, MR in 3 phase meter. But when trying in US i am getting the following error. I have checked passwords and they are correct as everything is working in guruxdirector perfectly.
