Raspberry SMS-USB-Stick nicht erreichbar - wie das mitkriegen ?

[DL8EI Ralph]

Hallo, ich betreibe einen Raspberry Pi3, auf dem FHEM läuft.
Zwecks Meldungen ist ein USB-Stick mit SIM angesteckt. Der schickt mir SMS, das läuft gut.

Problem:
manchmal ist der USB-Stick vom RasPi nicht erreichbar - warum auch immer - , das steht dann nach einem Sendeversuch auch so im Log. Das ist fatalerweise zu spät.
Zieht man ihn kurz raus und steckt ihn nach 5 sek. wieder an, dann ist er wieder erreichbar.

Meine Frage:
was ist wie zu tun, damit FHEM das vorher mitkriegt, den USB-Stick abwirft und dann wieder einloggt ?

Hallo DL8EI Ralph,

poste doch mal ein list deines Devices, dass den log-Eintrag macht - dann haben wir was Konkretes.
Es gibt viele Möglichkeiten auf ausbleibende Reading-Updates oder Änderungen von Readings zu reagieren und sich informieren zu lassen.

Ich lasse mich bspw. über den Status von I/O-Devices wie folgt informieren:

defmod myHmUARTLGW_notify notify myHmUARTLGW.*:.*disconnected.*|myHmUARTLGW.*:.*ok.* \
{fhem "set Pushover.Nachricht msg 'HOMEMATIC UART-Modul' '$NAME is $EVTPART1 !!';; \
set PushNotifier.Nachricht message HOMEMATIC UART-Modul _$NAME is $EVTPART1 !!;;";; \
Log 3, "HOMEMATIC UART-Modul: $NAME is $EVTPART1 !!";;}
Die Push-Dienste müssen natürlich auch definiert sein, sonst geht es nicht.

Viele Grüße Gisbert

Hallo Gisbert, Danke dafür, aber das trifft es leider nicht, weil der USB-Stick FHEM nicht bekannt ist, sondern nur dem Linux des Raspberry.

Der SMS-Sendebefehl sieht so aus:

{system ("gammu sendsms TEXT 017....... -text 'WasserMelder Ueberschwemmung' ")}Ich kenne mich mit Linux kaum aus, schreibe meist nur ab.
Laienhaft stelle ich mir vor, dass es auf dem RasPi eine Art Service gibt, der das Einschlafen des Sticks im Linux bemerkt, das meldet und ihn mit einem system-Befehl wieder aufweckt.

So blöd das jetzt ist, aber da musst du im ersten Step schauen was/ob aus Sicht des Betriebssystem für ein Problem besteht.
Dann kann man überlegen wie damit umzugehen ist.

Das heisst im Fehlerfall mal schauen ob sich mit dem Kommando "dmesg" was an den USB Ports sehen lässt bzw. auch im syslog.

Das wäre meine erste Idee (auch nur Basiswissen vorhanden).

[Wernieman]

Und der USB-Stick wird bestimmt als "serielles tty" Device erkannt ... ist das im Fehlerfalle da?

War wir Deinen USB-Stick und die Config nicht kennen .... Wie ist überhaupt "gammu" configuriert?

Obiger Ansatz ist gut. Plan ist, das regelmäßig von FHEM aus zu prüfen und zu reagieren.
Aber dafür mangelt es mir an Linux-Wissen. Deswegen erbitte ich etwas "vorgekautes".

Und der USB-Stick wird bestimmt als "serielles tty" Device erkannt ... ist das im Fehlerfalle da?

Es ist ein tty-Device. Muss auf den nächsten Fehlerfall warten um das nachschauen zu können.

War wir Deinen USB-Stick und die Config nicht kennen .... Wie ist überhaupt "gammu" configuriert?

Muss ich schauen, aber i.d.R. funktioniert es ja

Aber eventuell können WIR aus der Config rauslesen, was Dir helfen könnte .....

....Kommando "dmesg" was an den USB Ports sehen lässt

brachte diese Liste zutage

Leider nur ein Teil der Liste, das Forum hier wollte nicht alles.....
Davon verstehe ich nicht alles, aber meine Spannung soll nicht ausreichen bzw. schwanken.
Eine Messung ergab 5,17V und 3,24V an den Stiften des RasPi. Das scheint mir normal.
Ist Euch anderes bekannt? Was wäre zu tun?
Ich verwende das Original-Netzteil, das ich mit dem RasPi zusammen kaufte.

[RalfRog]

Da gibt es definitiv kompetentere FHEM'ler als mich, aaaber:

Ohne in die Ausgabe weiter einzusteigen denke ich, dass "Under-voltage detected!" zu Problemen führt/führen kann.
Inbesondere auf den USB Ports (hatte ich auch).
Ich meine mich zu erinneren irgenwo mal gelesen, dass der Rasperry in Fällen von Undervoltage intern Komponenten  abschaltet.

Das wäre aus meiner Sicht als erstes zu lösen.
Ich habe daher ein Meanwell-Netzweil mit regelbarem Ausgang um auf 5,2 Volt zu kommen und möglichst kurze Zuleitungen mit "dickem" Durchmesser. (weisss nicht mehr genau ob es AWG24 oder sogar 22 war)
Das ist bei USB-Datenkabeln oft nicht gegeben.


Edit:
das sieht definitiv nicht gut aus:

Ich kann Deine Vermutung mehr als Bestätigen.

Im dmesg Auszug ist folgendes auffällig:

Er hat ein Voltage Problem und anschließend runter/hochgefahren. Dieses muß zuerst gelöst werden, bevor wir weiter debuggen können.
Hinweis: Ethernet ist beim Pi3 über "USB" angeschlossen, deshalb kommt auch dort eine Meldung.

Kleine Frage: Was hast Du alles zusätzlich über USB angebunden?
Und .... USB-Handy-Sticks können viel Strom ziehen. Evenmtuell zu viel für den "Kleinen", d.h. könntest Du zusätzlich mit einem aktiven USB-Hub testen?

Das dürfte ein Problem sein schon im Boot-Prozess kommt:

BtW: Was ist das überhaupt für ein System? Aktuell??

[DL8EI Ralph]

Mache gerade einen Versuch.
Habe auf einer 40polige Steckleistenbuchse mal die Grounds durchverdrahtet und
die 5V-Pins mit 4700uF und die 3V-Pins mit je 470uF gepuffert.
Die Spannungszappeleien sind nun weg. Die connects / disconnects auch.
Ich schaue mal, ob das so bleibt und werde berichten.

BtW: Was ist das überhaupt für ein System? Aktuell??

Das ist eine gute Frage. Ich weiß nicht, wie man das abfragt und was denn aktuell wäre ?
Auf blauen Dunst ein update machen scheue ich. Never touch ....

Ich habe die Mühle aus einem Erbfall übernommen und versuche mich durchzuwursteln.

[RalfRog]

Trotz der Kondensatoren kannst du mit Hilfe von
  vcgencmd get_throttled
auf der Konsole checken ob ein Unterspannungsproblem bestand/besteht
throttled=0x0      aktuell kein Problem und in der Vergangenheit auch nicht, sollte die Ausgangslage sein
throttled=0x50000  aktuell kein Problem aber in der Vergangeheit under voltage und throtteled
(https://forums.raspberrypi.com//viewtopic.php?f=63&t=240215#p1466221)

bzw. hier im Forum https://forum.fhem.de/index.php?topic=112722.0

So hast du die Möglichkeit z.B. im Verlauf der nächsten Tage zu schauen ob etwas mit der Spannung war.


einfach mal was zur Stromversorgung http://www.elektronik-kompendium.de/sites/raspberry-pi/1912111.htm

[herrmannj]

plus 1 für meanwell 5V (eingestellt auf 5.2V) und USV (zb PI USV+ mit Akku)

Ansonsten ist es nur eine Frage der Zeit und die SD Karte geht ins Nirvana. Falls die Spannung anders gepuffert ist, kann man auf die USV natürlich verzichten.
