IR-Schreib-Lesekopf

jossie67 · Post by **jossie67** » Friday 02 January 2015 12:34

I have Landis+Gyr ZME120ACd and a IR-Schreib-Lesekopf from Udo
The IR-Schreib-Lesekopf is connected to the raspberry on /dev/ttyUSB0
I added the IR-Schreib-Lesekopf as an "SO Meter USB" on serial port /dev/ttyUSB0.
In the setup, I can change to Baudrate only to 9600 or 115200, my Landis+Gyr uses 300 Baud.
Where can I change this setting in to 300 Baud.

I have the same kind of problem with my Landis+Gyr ZCF120ABd. I won't get any reading from IR-Schreib-Lesekopf on my RPI.

Code: Select all

pi@RaspberryPi ls -l /dev/serial/{by-path,by-id}/*
lrwxrwxrwx 1 root root 13 Jan  1  1970 /dev/serial/by-id/usb-RFXCOM_RFXtrx433_A1YI4T4I-if00-port0 -> ../../ttyUSB1
lrwxrwxrwx 1 root root 13 Jan  1  1970 /dev/serial/by-id/usb-Silicon_Labs_USB-IR-Kopf_0092D858-if00-port0 -> ../../ttyUSB0
lrwxrwxrwx 1 root root 13 Jan  1  1970 /dev/serial/by-path/platform-bcm2708_usb-usb-0:1.2:1.0-port0 -> ../../ttyUSB1
lrwxrwxrwx 1 root root 13 Jan  1  1970 /dev/serial/by-path/platform-bcm2708_usb-usb-0:1.3:1.0-port0 -> ../../ttyUSB0

[b]pi@RaspberryPi ~ $ cu -l /dev/ttyUSB0 -s=9600 --parity=none[/b]
Connected.

Nothing pops up on my RPI. I have tested the IR-Schreib-Lesekopf with my windows laptop. It shows up and reads the data.

The output looks quite similar to that of a smartmeter, but similar != same.
I think Domoticz can't parse it, because it doesn't know this kind of telegram.

Maybe it can be implemented

Bit offtopic but can anyone say if I can buy ready assembled IR-Schreib-Lesekopf from somewhere?

How can i send the request to be implemented?

You can place a feature request here: http://www.domoticz.com/forum/tracker.php?p=2 and discuss about it here: http://www.domoticz.com/forum/viewforum.php?f=5 (be sure to read the rules of that subforum).

I think for one reason is that the P1 serial port is opened with 9600 baud, Even parity, 7 bits
Maybe your serial protocol is different ?

what you can try:
install 'ser2net' and configure this that port 2000 is opening the right serial device, with the right parameters (in raw mode)
now when you connect from another machine to this port 2000, you should see the serial output

in domoticz, you can also setup a P1 meter with LAN interface

Maybe this will work

Probably later this year you will get a P1 Smart meter (i think everyone in holland will get one)

Gizmocuz,

I don't think I will get a new smart-meter this year, my house was build in 2008.
I have it working now also with stadverwarming, see also

I have called Stedin en our area isn't scheduled yet. They have planned it somewhere from 2017 until 2020. Just because it is working fine for them now.

In our area ENEXIS is the provider.
When I called them to tell that my meter didn't switch from high to low tariff,
it was immediate replaced by a smart meter.
In my case it was the truth (but who cares?).

Hope this helps

I have tried to get my Lesekopf working. I am getting one step closer but am stil far far away. I am sending

Code: Select all

pi@raspberrypi ~ $ echo -e "\x2f\x3f\x21\x0d\x0a" > /dev/ttyUSB0
pi@raspberrypi ~ $ cat /dev/ttyUSB0
(ER23)

Does anybody knows more?

Thanks! I will give it a try. I give up and wait for support within Domoticz

. Too much noob for this.

How do I see on what USB port the IR-Lesekopf is connected?
When I use 'dmesg | grep ttyUSB' I see nothing, so it is a bit difficult to amend the python script which reads the Kamstrup.

Thanks!
