Hi,
I have tried to read out the Landys-Gyr E650, finding out it's a DLMS meter
I'm using the following hardware:
- Raspberry Pi 3B
- A RS485 cable connected to the meter, installed by the network operator.
- the RS485 cable connected through ch341-uart converter through usb on the raspberry Pi
Having cloned https://github.com/gurux/gurux.dlms.python and installed all the dependencies, I have tried to get it working through, but so far I get the following outputs:
```
~/Gurux.DLMS.Python/Gurux.DLMS.Client.Example.python $ python main.py -S /dev/ttyUSB0

ClientAddress: 0x10
ServerAddress: 0x1
Data send failed. Try to resend 1/3

What else could I try ?

I was able to get a meter-values reading with .map110 with the same cable from a windows10 pc.
The link for the logs and the reading can be found here: https://blocklabnl-my.sharepoint.com/:f:/g/personal/ilhan_blocklab_nl/E…
I uploaded this as maybe the communication log might help with resolving how this smart meter need communication

What are the Unknown objects and the Scalar issues ?
To clarify, I'm using the `Gurux.DLMS.Client.Example.python` folder for testing all of this. Looking forward to your support. Thank you.
Hi,
Hi,
Unknown objects are manufacturer defined custom interfaces.
Those interfaces are not defined on the standard. Meter manufacturers usually don't use them anymore because it breaks the compatibility.
We'll make simulated device from your log and check this scaler issue.

Great news, finally we are able to get a reading.

Have a hard time understanding the context in the messages, what the readings are.
Furthermore the read and write denied messages, what are these about, am I missing something.
Do you have any examples if I wanted to build an API around this ?

Hi,
Hi,
You need to change client address. I can't remember what L+G is using. It might be 17.
Try with this:
sudo python3 main.py -S /dev/ttyUSB0 -r sn -a Low -P 00000000 -c 17

No, an exsys adapter was bought for rs485 usb
Hi Mikko,
Hi Mikko,
Remember the cheap rs485 extension in which I started the topic with, at home I get it working. I'm really starting to think it's the smart meter that is the production has a bad rs485 connection that isn't working. I had again no luck with the Exsys rs485 usb on the location.
I still need your support on the following errors below, I know you gave me already in your latest post advice on how to deal with the errors but it's not helping:
So when I do the most simple command in Gurux.DLMS.Client.Example.python$ sudo python3 main.py -S /dev/ttyUSB0 -r sn I get the following output https://paste.ubuntu.com/p/6Bm5cs5kDZ/
I get the following errors: Access Error : Device reports Read-Write denied.
With the command you gave, it is not reading it at all: python3 main.py -S /dev/ttyUSB0 -r sn -a Low -P 00000000 -c 17 the output is here: https://paste.ubuntu.com/p/SyHRNDCkZb/
Is this because the client address is wrong or the password ?
Hi Ilhan,
Hi Ilhan,
Read-Write error is coming because those objects are not configured or implemented totally.
The reason might be either. password or client address can be wrong.
BR,
Mikko
Ok thank you,
Ok thank you,
If I'm looking to just get the latest generated energy (solar) from a meter every 5 minutes, how woudl I go about this with the python library?
Hi Ilhan,
Hi Ilhan,
You need to know the object type and the logical name of the object. Then create a scheduler that makes a connection to the meter and collects data. There is -g parameter in the client example that reads wanted object using logical name and attribute index. Check that.
BR,
Mikko

From 1 up the errors just keep getting worse. Any ideas?
Hi Ilhan,
Hi Ilhan,
Those are not errors. Meter is implementing non-standard interfaces and client don't know what to do with them. You can just ignore Unknown objects.
You are now reading attribute index #1 and it's local name. Change index to #2 if you want to read value.

Ok, I'll get back on get the right index value, right now another pressing issue. Currently at the office of the DSO that prepare the meters.

I cannot get the any value out, while calling the overal

I have asked the DSO about authenticaiton and they are saying that is should be no issue with the standard password of 00000000
This is the output of a whole Gurux Client:

Hi,
Hi,
sudo python3 main.py -S /dev/ttyUSB0 -r sn -c AKS_THIS_FROM_THE_MANUFACTURER -s 1 -a Low -P 00000000
If this is Indian meter, AKS_THIS_FROM_THE_MANUFACTURER is 32.
Note! Client example can handle only string passwords. If 00000000 is hex string you must hard code it.
BR,
Mikko
Hi again,
Hi again,
You mean hardcoding the following line in GXsettings.py:
elif it.tag == 'P':
# Password
self.client.password = it.value
to:
self.client.password = 00000000 ?
Furthermore does -c require additional steps other than filling in Authentication or Encrypted after the parameter?
I'm from the Netherlands, sure they are not Indian meters, but also the DSO and Manufacturer, don't know much about the authentication, so if you have any idea's how to get past this, please let me know. Thank you so far for helping me out.
Hi,
Hi,
Try with this:
self.client.password = GXByteBuffer.hexToBytes("00000000")
Try with this to use Low authentication:
-c 17
Note! 'c' and 'C' are doing different things. 'c' changes client address and that is what you need to do.
BR,
Mikko
That didn't work. Trying to
That didn't work. Trying to find the -c value from the manual:
For point-to-point connections, the device does not need to be specially addressed. However, with multi-drop, all devices connected to a bus system (RS485 or CS) must have their own address for individual access. This address is called the physical device address. In fact, even two physical device addresses are used, one for the IEC protocol (IEC device address) and the other for the DLMS protocol (HDLC device address). Unless otherwise specified on the order, the following parameter values are set as defaults for these physical device addresses:
- Physical IEC device address = serial number (printed on face plate of device), e.g. 73852799.
- Physical HDLC device address = last 4 digits of serial number plus 1000 (because with dlms the range of addresses is limited and some addresses are reserved), e.g. 3799 for a serial number 73852799 (2799 + 1000 = 3799).
The serial number of the meter I'm trying to read is 50399974, this is the NO written on the meter and not on the modem module attached to it.
Tried IEC:

Hi Ilhan,
Hi Ilhan,
There is a misunderstanding. If you want to use meter address then you can give it using -n parameter.
-n 50399974
If you can connect without authentication you don't need to change server address.
You need to give the correct password, authentication level and client address.
I propose that you try to connect with GXDLMSDirector first.
Select L+G as manufacturer and set the correct password.
I don't know is 00000000 hex or not. You just need to try to find the correct parameters.
BR,
Mikko
Hi Kurumi,
Hey Mikko,
Did some research with the Map110 software and back with some details:
With map110 you need different client levels that correspond the different client addresses. With [0] I cannot get any data out, with level [1] I can get the meter values out. Level 1 has client address 32
I have taken screenshots of the settings, downloaded the logs and the corresponding values.
Please see this link for the meter-values logs and attachments of the settings:
https://blocklabnl-my.sharepoint.com/:f:/g/personal/ilhan_blocklab_nl/E…
Client [1] requires a low level authentication that requires a password: See the attachments:
-Device Settings - Access Levels
- authentication level - Client 1 Data Collection - secret string
Coming back to Gurux.Client my command after some playing around I found the one that works:
sudo python3 main.py -S /dev/ttyUSB0:9600:8None1 -r sn -c 32 -s 1 -a Low -P 00000000
-------- Reading 3 8224 Ch. 1 Sum Li Active power+ (QI+QIV) Time integral 1 Rate 0 (0 is total)
Index: 1 Value: 1.1.1.8.0.255
Index: 3 Value: 0.1, Unit.ACTIVE_ENERGY
Index: 2 Value: 2356106.5
-------- Reading 3 8392 Ch. 1 Sum Li Active power- (QII+QIII) Time integral 1 Rate 0 (0 is total)
Index: 1 Value: 1.1.2.8.0.255
Index: 3 Value: 0.1, Unit.ACTIVE_ENERGY
Index: 2 Value: 18221626.2
I get the values I need, so this already a great achievement!
They however have a different decimal point then the Map110:
1-1:1.8.0,2356","1065,kWh,Active energy import +A (QI+QIV),Energy Total
1-1:2.8.0,18221","6262,kWh,Active energy export -A (QII+QIII),Energy Total
1st reads 2356kWh, 2nd 18221 kWh.
The comma after those are the decimals of kWh.Why is the format different ?
We can figure a way out with this though

Now coming to the real meter that is connected to solar panels, I can access it remotely with a PI.
With the same command : sudo python3 main.py -S /dev/ttyUSB0:9600:8None1 -r sn -c 32 -s 1 -a Low -P 00000000
I get the following output:
Data send failed. Try to resend 1/3
Data send failed. Try to resend 2/3

Any idea's why ?
Hi Ilhan,
Hi Ilhan,
We are showing the value that is read from the meter.
2356106.5 Wh
Map is shown it as kWh
2356kWh
Multiple the value by 1000 and you get kWh.
Check your baud rate. Are you using a serial port or optical port with PI?

All solved `python3 main.py
All solved `python3 main.py -S /dev/ttyUSB0:9600:8None1 -r sn -c 32 -s 1 -a Low -P 00000000 -g 1.1.2.8.0.255:2`
does the trick now, seems that the rs485 cable wasn't placed well. Thank you for your support.
Hi Ilhan,
Hi Ilhan,
Thanks for letting me know the reason. Cables are causing most of the problems. Happy coding.
BR,
Mikko
