no logging

[smarteshome2020]

Hallo, ich versuche es mal in Deutsch :-)
Ich bin gerade dabei mit einen Volkszähler auf Basis eines PI zu bauen. Mir gelingt es einfach nicht die Daten die ich vom IR bekommen per vzlogger an die middleware zu übergeben. Könntet mir bitte jemand helfen? :-(

Output cat /dev/ttyUSB0

index = true, allerdings immer noch keine Daten :-(

this is not a support forum, but a place to report issues with the software itself (bugs, feature requests).
there's the -users mailing list: https://wiki.volkszaehler.org/contact
and i heard that there's a forum somewhere on the internet.

Output cat /dev/ttyUSB0

1-0:1.8.0*255(009598.4687*kWh)

        "protocol": "sml",
       "device": "/dev/ttyUSB0",

sml is a binary protocol, the data from your meter is clearly not sml, probably rather d0.
you did not mention what model of meter you are trying to read.
can you say what made you assume it's sml?
we might have to improve some documentation.
the parser could also print some warnings if it finds the data it receives is garbage.

the parser could also print some warnings if it finds the data it receives is garbage.

that is essentiallly a libsml issue (and somewhat blocked by volkszaehler/libsml#17 )
we read from the meter using sml_transport_read(): https://github.com/volkszaehler/libsml/blob/master/sml/src/sml_transport.c#L59
which silently skips over any unrecognized data.
(it only prints a warning for valid but unrecognized sml sequences.)

we need to either improve the sml_transport code and the libsml API,
or replace sml_transport with local code.

=> a short investigation shows: the sml_transport_read() api is completely broken.
there's no way for it to keep state between invocations (it's not passed an sml_buffer struct that would be used for that.)
and it can't return anything to the caller because it only returns the number of bytes read.
(we already enhanced this by allowing to return 0 to indicate read errors.)
sml_transport needs to be deprecated and replaced.

Thanks, i don*t know why im using SML, i change to S0 and it looks better. I will test it.

Thanks a lot

i'll just leave this link here,
it has example configurations for lots of meters, including the correct protocol:
https://wiki.volkszaehler.org/hardware/channels/meters/power/edl-ehz

[J-A-U]

we might have to improve some documentation.

Doesn't strike me like @smarteshome2020 used our wiki. E.g. "port": 8080,
