Smartmeter2

---

@bertreb

thats correct.

@dennist , i’m also using the smartmeter2 plugin and did some time ago a test on a new version of the plugin (with node v4 an v8 support). I was waiting for updates of the current plugin, but that seems not to happen. Today i checked my test version and it still works. So i published the Smartmeter3 plugin.
I also made de RegEx string per data item configurable. You can use it if a smartmeter version and the data differs from what i tested.
The plugin will probably be visible tomorrow in the plugin section of Pimatic. It would be nice if you could test it.

Is there a way to get this ir reader working with your script?
https://wiki.volkszaehler.org/hardware/controllers/ir-schreib-lesekopf-usb-ausgang

Hi, the plugin receives data from any serialport source and converts ascii (human) text to data fields. Smartmeters generate human readable ascii datagrams/records.
Looks like the IR reader you are describing generates binairy data. So depending on what you want to extract from the binaire data, Regex (with my Plugin) could be an option or another type of filter/plugin is needed.
Do you know what the data protocol is?

SML as I understand

I did a short check on SML and Volkszaehler and it seems that my plugin is not able to read the data. Probably you need a plugin with capabilities based on the smartmeter-obis library. I assume you did look already at the pimatic-volkzaehler plugin?

@bertreb that would be nice. I will check this in the evening. Thanks for your support.

Impressive log with several warnings but looks like the plugin was successfully installed?

@bertreb I can confirm that everything is working. Thanks a lot.

@bertreb said in Smartmeter2:

I did a short check on SML and Volkszaehler and it seems that my plugin is not able to read the data. Probably you need a plugin with capabilities based on the smartmeter-obis library. I assume you did look already at the pimatic-volkzaehler plugin?

I am not using the plugin. I have installed VZLogger and read the output via LogWatcher into Pimatic. But I am still watching for a more simple way.

@OrTiN, i’m planning an update of my smartmeter3 plugin and will change to the smartmeter-obis library. This library has a lot of functionality for reading smartmeters. It’s should be compatible with node v4 and v8 (v4 still to be tested)
I have already a working DSMR device. Its easy to add also a SML device. I’m not familiair with the OBIS codes used in SML smartmeters. Do you have the OBIS codes you’re using in your setup?

Upps sorry have overseen this… Would be really nice if you can do this.

I can find this in my vzlogger.log:

This fits to the first table of Iskraemeco MT175 here.

Hi, thanks for the info. I will publish a first version for testing today. The plugin will be called smartmeter-obis.

Will test it

First test shows this:

Thanks, seems like an essential option to work I will fixed it asap

I corrected the protocol name and published a new version 0.0.9 for testing

Unfortunatelly still something wrong. Now this is shown:

Any idea? Today I can only test. Maybe I will find some time in the evening to check the code. I am not a developer, but maybe I can somehow help.

I my vzlogger config I must config the parity with 8n1. Maybe this is the problem here.

In the past I played a little bit around with following shell script. It gives me data, but not the right one.

#!/bin/bash
# read and evaluate SML output received from EMH eHZ
 
# set serial device
INPUT_DEV="/dev/usb-ir-lesekopf0"
 
#set $INPUT_DEV to 9600 8N1
stty -F $INPUT_DEV 1:0:8bd:0:3:1c:7f:15:4:5:1:0:11:13:1a:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0
 
SML_START_SEQUENCE="1B1B1B1B0101010176"
METER_OUTPUT__START_SEQUENCE=""
 
while [ "$METER_OUTPUT__START_SEQUENCE" != "$SML_START_SEQUENCE" ]
do
        METER_OUTPUT=`cat $INPUT_DEV 2>/dev/null | xxd -p -u -l 460`
        METER_OUTPUT__START_SEQUENCE=$(echo "${METER_OUTPUT:0:18}")
        if [ $METER_OUTPUT__START_SEQUENCE != $SML_START_SEQUENCE ];
        then
                echo "missed start and trying again..."
                #exit 1 
        fi
done
 
let METER_180=0x${METER_OUTPUT:390:10}
VALUE=$(echo "scale=2; $METER_180 / 10000" |bc)
echo "Meter 1.8.0 (from plant):    " $VALUE "kWh"
 
let METER_180=0x${METER_OUTPUT:347:10}
VALUE=$(echo "scale=2; $METER_180 / 10000" |bc)
echo "Meter 2.8.0 (to plant):      " $VALUE "kWh"
 
let METER_180=0x${METER_OUTPUT:518:8}
VALUE=$(echo "scale=2; $METER_180 / 10" |bc)
echo "Total effective power (+/-): " $VALUE "W"

I really have no idea waht is 0x${METER_OUTPUT:390:10}, 0x${METER_OUTPUT:347:10} or 0x${METER_OUTPUT:518:8} and how I can get to the right value for current usage or total usage. But maybe it helps you to fix the last details.
