measuring gas/water (Landis & Gyr B25/ZMF120AC)

[PietjeNL]

Meters are installed, now looking into how to get there data out.

[Freemann]

Could you post some pictures and info about the meters (brand, type, available PX's etc.)?

I'm still waiting for Stedin's response on my questions.

[PietjeNL]

E-meter:
Landis & Gyr: ZCF120ABd
G-meter:
Flonidan Uniflow G4SRV

[Freemann]

Does it have a enable and accessible P1 or HAN port?

[PietjeNL]

P1 is accessible and enabled.

[Pieterpaul]

Can you explain how you can access the P1 port of this device?

It says "Supply Voltage: 5V" ,is this cable going to work?

Hi guys,

I'm new here, but I'm also interested in what comes out of the Stedin Smart Meter.
Stedin installed the Landis + Gyr ZCF120ABd meter last week, and it comes with an P1 port, although the installer couldn't tell what the port was for, nor is there any information in a manual of some sort.
This is is pic of the meter:


And here you have the P1 port, on the right:


I wiped out the serial numbers, if you don't mind

As you can see, it is almost identical to the Landis & Gyr ZMF120AC, but with addition of "DSMR 2.2+" text on it (hey, should this not be DSMR 4.0 ?) and the p1 port, a normal accessible RJ11 connector, on it.

Thanks to the info from Joost, I connected the stuff using home made connector: ftdi ttl-232r-5v USB on one side, RJ11 (using a "normal telephone plug", which means pin 1 and 6 are not connected) on the other.
Rewired red (=5 volt) to RJ11 pin 2 (to keep request line high), black (ground) to RJ11 pin 3 and yellow (rxd) to RJ11 pin 5 (data).
Reprogrammed the chip to invert RXD line ( because DSMR specs states: SPACE “0” as > 4V , MARK “1” as < 1 V)
Plugged the thing in a router with openWRT on it, and this is the output I get, when setting the /dev/ttyUSB0 to 9600 baud, 7 data bit, even parity, 1 stop bit.

This is an example of the 'telegram' I get, every 10 seconds:

Code: Select all

/XMX5XMXABCD1000..deleted serial..

0-0:96.1.1(4B3832..deleted serial..)
1-0:1.8.1(000149.539*kWh)
1-0:1.8.2(000153.153*kWh)
1-0:2.8.1(000000.000*kWh)
1-0:2.8.2(000000.000*kWh)
0-0:96.14.0(0001)
1-0:1.7.0(00000.84*kW)
1-0:2.7.0(00000.00*kW)
0-0:17.0.0(999*A)
0-0:96.3.10(1)
0-0:96.13.1()
0-0:96.13.0()
!

I tried with a "cheap" USB - to -Serial cable first, soldered an invertor chip on the RXD line, this will cost around 3 or 4 euro's, but the resulting signal was very, very terrible and distorted, when looking to the result on my scope. Therefore, I choose to use the FTDI one instead, although those will cost me around 16 euro's. Those cables can be reprogrammed to invert and do offer a much better quality.

In response to Freemann;
I guess the 3.3V version will work too (1 euro cheaper), but since specifications clearly states "SPACE “0” as > 4V , MARK “1” as < 1 V", a legimate "0" should be 4V or higher, not 3.3V or higher...

Dont know if u have a gas meter aswell, but it seems the meters are not connected yet by Stedin.
Had the same, will solve itself in a few days, then u also have the gas readings.

[merty]

Ah yes, forget to tell; My house is not connected to the gas network. Instead, we have district heating. So, it is quite normal you will not see any gas metering results...
Would love to if they connect the water or heating meter though...

[PietjeNL]

Btw lol regarding the removal of the seriel number, but its still there in plain sight, u forgot the barcode

[Freemann]

I requested a new meter and order a 5v FTDI cable.

I'm very curious when if/when i hear something from Stedin.

Hello,

I've recently purchased a cable from Udo for reading out my smart meter. Unfortunately I haven't succeeded in achieving reading out any useful information from my meter. Hopefully someone can help me.

I have the Landis+Gyr ZCF120ABD meter:


According to the specifications (in German), the communication interface is standarized IEC 62056-21.
My meter doesn't have any physical P1 port for a RJ11 connector, only an infrared P1 port on the front (top-right).

I connected everything up using Udo's cable on my Windows 7 laptop and used HTerm to try to get something from the meter. Here are the results:

Code: Select all

==> /?!<\r><\n>
<== /LGZ5ZCF100AC.M40<\r><\n>
==> 6000<\r><\n>
<== <2>(ER23)<3><20>

Unfortunately the identification message doesn't follow the format described in the 'Reading the IR port of an IEC 62056-21 Smart Meter' topic.
Also it seems that the meter is giving an error. Does this mean my meter is locked?

[Udo]

==> 6000<\r><\n>

Hi,

is it a typo? 6000<\r><\n> ? You have to send <6>000<\r><\n>
Did you try http://www.meter-test-equipment.com/dow ... 07pack.exe ?
