<p>Guten Morgen Klaus,</p>
<p>vielen Dank für Deinen Vorschlag. So wie ich es sehe wartet auch
der SMLReader auf eine SML-Startsequenz.</p>

Hichi, Raspi usw, alles ok, Mega Aufwand, aber damit hast ( hofffentlich) die Daten erst mal zur Verfügung - kannst dann damit per MQTT was auch immer anstellen
TX brauchen übrigens aktuell die wenigsten Zähler

Betreff: [vz-users] Auslesen eines ISKRA MT175
Hallo Miteinander,
ich bekomme beim Versuch meinen Zähler auszulesen keine vernünftigen Daten heraus und hoffe auf eure Hilfe.
Zähler: ISKRA MT175-D1A51-V22-K0t (mit PIN frei geschaltet), Lesekopf:
Hichi USB an Raspberry Pi Model B Plus Rev 1.2 mit Raspbian Bullseye (up-to-date).
Echo-Test mit weißem Papier klappt ohne Probleme.
Die Sendediode des MT175 sendet auch alle 1-3 Sekunden etwas (geprüft mit Handy-Kamera).
Installation des vzlogger hat auch geklappt.
Ich habe mir folgendes config-file zusammen gebaut (Parameter gemäß wiki Seite für den MT175):
{
"retry" : 3,
"verbosity" : 15,
"log" : "/var/log/vzlogger.log",
"local" : {
"enabled" : true,
"port" : 8081,
"index" : false,
"timeout" : 30,
"buffer" : 600
},
"meters" : [{
"protocol" : "sml",
"enabled" : true,
"device" : "/dev/ttyUSB0",
"parity" : "8N1",
"baudrate" : 9600,
"aggtime" : -1,
"aggfixedinterval" : false,
}]
}
Im Logfile sieht das dann so aus:
[May 16 18:50:04][main] vzlogger v0.8.1 based on
tags/v0.8.1-0-g0671359029 from Sun, 23 Apr 2023 15:16:41 +0200 started.

[May 16 18:50:04][mtr0] Number of readers: 32 [May 16 18:50:04][mtr0] Config.local: 1
Dann passiert nichts mehr.
Also versuche ich erst mal direkt auf der Schnittstelle zu lesen und zu schauen was da ankommt.
Dazu verwende ich ein kleines Python-Programm:
#!/usr/bin/python
import serial
BAUDRATE = 9600
print("opening port")
co = 0
out = ''
# Serial Port 9600 Baud, 8N1
port = serial.Serial(port='/dev/ttyUSB0', baudrate=BAUDRATE, bytesize=serial.EIGHTBITS, parity=serial.PARITY_NONE, stopbits=serial.STOPBITS_ONE, timeout=1) # Serial Port 9600 7E1 #port = serial.Serial(port='/dev/ttyUSB0', baudrate=BAUDRATE, bytesize=serial.SEVENBITS, parity=serial.PARITY_EVEN, stopbits=serial.STOPBITS_ONE, timeout=1)
while True:
input = port.read()
out = out + " " + input.hex()
co += 1
if (co > 25):
print(out)
co = 0
out = ''
Es gibt keinen wesentlichen Unterschied bei der Ausgabe, egal ob ich mit
7E1 oder 8N1 lese.

Okay, jetzt ist klar, wieso der vzlogger kein SML findet, der SML-Header
1b1b1b1b01010101 kommt nicht vor. Allerdings so etwas Ähnliches (1b 12
12 12 00 00 00 00). Dann habe ich einige Umpositionierungen des Lesekopfs ausprobiert. Ich dachte, vielleicht sitzt der irgendwie schief drauf, leider ohne Erfolg es kommen immer ähnliche Daten wie oben.
Fällt euch dazu etwas ein? Ich vermute irgendetwas an der seriellen Kommunikation ist falsch eingestellt. Aber was?
Vielen Dank, tuxlog
