obis code 167 not found

[rapkin61]

code line 200:

sml167 = parseSML(data_hex, "167", '070100100700ff', 28, 8)

does not seem to find any data, probably because '070100100700ff' cannot be found in the data stream. Got a new meter today: eHZ-KW8E2A5L0EQ2P

[soenkegissel]

I have the same problem with this meter. Got it 4 weeks ago from Westnetz (Germany). Had another meter since 2011, worked perfectly with optical sensor and OBIS. Now the eHZ-KW8E2A5L0EQ2P only sends a anonymous OBIS block. After entering the pin, the menu entry "InF" is not to find. (https://www.manualslib.de/manual/216737/Emh-Metering-Ehz-K-Bia-D-1-00.html?page=24#manual)

I am in contact with Westnetz, hope they send a new meter with complete OBIS block.

The whole smart meter exchange program in Germany is initiated for letting customers know about their consumption. Not even slightly possible with eHZ-KW8E2A5L0EQ2P. Just sad...

@rapkin61, for sure, you can only parse data, that is send by the meter. Is eHZ-KW8E2A5L0EQ2P sending "167" data? maybe you should check the whole stream, what kind of data/values are being send by the meter. by the way, I do no longer use this python script on a raspberry, instead I use an esp8266 device with a customized Tasmota software, which uses less power: https://tasmota.github.io/docs/Smart-Meter-Interface/

[rapkin61]

I'm not sure if the meter sends "167" data. When I look into that energy.logger.txt file, where the the hex data is written to - I can't find the obis code "070100100700ff" at all. Maybe I could dig further into this, if I had a chance to read that documents on volkszaehler.org, but the site is offline once again. Do you have an idea how I could check the whole stream?

esp8266 ... surely a good idea. I always wanted to get into this topic, but the time is somehow always missing ...

[dirkclemens]

@rapkin61, I assume you have verified, that your meter is sending ascii data and not binary, didn't you? Can you please post a sample snapshot from the data that you read from your meter?

[rapkin61]

I suppose the data format is correct, the other values ("180", "280") are parsed very well and the output matches the values on the display of the meter.

this is a short snippet of the data stream:

For "180" this was correct (it indicates a value of 0) as the meter was new, but the value of "167" remains 0 up to now. That is not plausible.

[dirkclemens]

@rapkin61, you are right, the "1.6.7" value is not included in the data you receive. So it seems that your meter is not capable of sending it. Not every meter is sending every value, depending of internal capabilities or other aspects. My meter e.g. sends only 1.8.0, 2.8.0 and 1.6.7 values.

070100010800ff --> 1.8.0 070100020800ff --> 2.8.0 070100010801ff -->1.8.1 070100020801ff --> 2.8.1 070100010802ff --> 1.8.2 070100020802ff --> 2.8.2

070100100700ff --> 1.6.7 not available

Das könnte auch daran liegen, dass für einige Werte der PIN beim Stromzähler eingegeben werden muss, vorher rückt der die Daten nicht raus. War bei mir auch so, ich habe einen ISKRA MT681 von Westnetz. Nach PIN-Eingabe sind 167, 367, 576 und 767 verfügbar, für Gesamtleistung und L1, L2 und L3.

[rapkin61]

... und woher bekommt man diese PIN?

[mdk2412]

Vom jeweiligen Messstellenbetreiber, z.B. der örtliche Versorger. Ich hab meine schlicht per Telefon angefordert und direkt mitgeteilt bekommen.
