Hi, I am new to Gurux. The reason I'm here is because I'd prefer to read data directly from smart meters (eHZ EDL-21) instead of taking the various indirect routes available.
I've taken a look at the protocol software. Congratulation on the choice of language and platform BTW. My question:
* you mention serial connections. Not many eHZ EDL-21 smart meters have these, do they? if so, connector type/cable type?
* I'd prefer to use the IEC 62056-21 optical readout head, but can't find one for under 50 Euro. That is what the entire eHZ costs in many cases. Any tips on a "poor-man's" optical readout here?
* last dumb question: any tip on soft emulators for smart meters to do software testing?
from the other thread, it appears that there is no easy "poor man's" optical head solution but there are some DYI options. The emulation would be valuable since developers could create software for a lowest-common-denominator device first, and then move on to specific devices from there on out... This would be my preferred approach.
Hi,
I have a Landis+Gyr 3phase meter with an optical readout port and DLMS is mentioned near this port. I sent SNRM data but the meter is just not responding. I tried 2400 Baud and 9600 but no response. I built the optical module and tested it with another device. It is able to send and receive data properly. This device is actually connected to the serial port of a micro-controller. Any suggestions please? Thank you.
Hi Kurumi,
Thank you for the reply. I am sorry I seem to have posted my question in an already existing thread. I thought I created a new thread. I will do so now. As suggested I will first try with RS232 and GXDLMSDirector and once I get some reply, I will switch to optical. Thank you once again.
Hi Kurumi,
Thank you very much for the suggestion. As suggested I will use GXDLMSDirector first via RS232 (cable) and then I will connect my optical drive/receive circuit to the serial port (need to make changes to driver accept +/- Volts on Tx ) and test the optical readout.
Hi Kurumi,
I connected a PC to the meter RS232 (through USB to serial converter). When I press the key on the meter I get "std_data" message on the LCD of the meter. Now when I connect using GXDLMSDirector, there is no reply from the meter. I am using only three wires Tx,Rx and GND for RS232. The meter has an RJ11 (6 pin) connector. Any suggestions? Thank you.
Hi kurumi,
The meter has Landis_Gyr Dialog CU-B4 module and I am connecting my PC to the serial port of this module. The connection is simple Rx,Tx and GND (No hand shake). Even the meter display shows STD_DATA. Thank you.
Optical Head
Hi,
You can use Optical Head also.
There has been some talk from Optical heads here:
http://www.gurux.fi/node/503
At least I do not know that there are any Smart Meter emulators.
We could do it if there are more people who are interested from it.

Thanks... emulation...

Good stuff!

Emulator
Hi,
You are right that optical heades are expencive.
As I told in my earlier email we could do the emulator if there are more peoples who are interested from it. We have to think about this...

Hi Nayani,
Please, create new topic if you have question.
L+G is using baud rate 300 as start baud rate and the it's changed to 9600. Use GXDLMSDirector to read your meter.

Hi Nayani,
Use baudrate 300 when using optical port. GXDLMSDirector will take care of everything.

Hi Nayani,
If you are using serial port try with 9600 and 4800 8None1.
What is your L+G model?

Meter is Landis+Gyr There is
Hi kurumi,
Meter is Landis+Gyr There is no specific mention of model number on the meter. I am not sure if "ZMD402CT.44" is the model number.

Hi Nayani,
Are using external serial port module? You can replace this module example TCP/IP module.
