Microsoft Mailsperre (gelöst)

2026-01-25T08:48:00+01:00

Betrifft alle Nutzer mit e-Mail-Adressen bei einem Microsoft-Maildienst (outlook.com, live.com, hotmail.com etc.): Microsoft haben das gesamte IP-Netz, in dem der OVMS-Server liegt, gestern abend um 21:00 Uhr CET auf deren interne Mail-Sperrliste gesetzt.

Der Server ist bei Microsoft offiziell als dedizierter Server registriert, Microsoft halten sich also hier nicht an ihre eigenen Regeln.

Die Entsperrung ist beantragt, wie lange dies dauert steht in den Sternen.

Update 16:51 Uhr CET: die Sperrung wurde seitens Microsoft aufgehoben, Mails an Microsoft-Domains werden wieder zugestellt.

    add information commads xsq climate|counter|mtdata|reset|start|total
- Nissan Leaf:
    ZE1 inital release
    Fix: Poll state not set to off when charging stopped by OVMS
    Enh: SOH_instrument now float not int to support ZE1 instrument values 
    Enh: Copy v.b.p.temp.max to v.b.temp so that max battery temp displays in app
- Smart EQ 453:
    DDT4all simple support, a full List of commands at www.smart-EMOTION.de
- VW e-Up (OBD): decode & display battery cell level health status & battery module
    health history, provide v.b.capacity (net capacity in kWh)
  New metrics:
    xvu.b.c.soh               -- Array: SOH [%] of each HV battery cell
    xvu.b.hist.soh.mod.   -- Array: SOH [%] history of each battery module (NN=01…14/17)
  New web page:
    /xvu/battsoh          -- Battery pack & cell SOH info
- Smart EQ 453:
    add timebased Pre-heat/cool Control 
      - can set at Website -> Smart ED/EQ 4.Gen -> Climate/Heater 
      - at App Features #4: on = 1 off = 2, #5 time like 05:15 = 515, #6 5/10/15 Minutes = 0/1/2
    add GPS powersaving mode at parking
    add 12V alert raised, the car starts the 12V charging process for 15 Minutes
    add Network type switch, option to lock LTE only. Needed, when the Provider has no Datastream at GSM
- CAN: add error flag decoding (included in can status output)
  New commands:
    can  explain [errorflags]    -- Decode error flags into human readable text 
- DBC Files
  Add unit support
  Add extended signals/multiplexing support
  Add support for enum values.
- OVMS Server v3: Ability to define less frequent MQTT communication to save data charges and power
  Events:
    Excludes clock.* events from being published at the start of every minute.
  New configs:
    [server.v3] events.legacy_topic  -- Whether to publish every event on the legacy /event topic as well as
                                        the MQTT-style topic. Defaults to true to preserve existing behaviour.
                                        Recommended to set to false if you don't use the legacy topic.
    [server.v3] updatetime.keepalive -- Max number of seconds to allow the MQTT connection to be idle before
                                        sending PINGREQ. Should be set slightly shorter than the network's
                                        NAT timeout and the timeout of your MQTT server. If these are unknown
                                        you can use trial and error. Symptoms of keepalive being too high are
                                        a lack of metric updates after a certain point, or "Disconnected from
                                        OVMS Server V3" appearing in the log. In previous releases this used
                                        the Mongoose default of 60. New default value 1740 aligns with
                                        observed Hologram timeout of 1800.
- Metrics

Apple/iOS App-Benachrichtigungen: Störung behoben

2025-05-20T10:38:00+01:00

Störung bei Apple/iOS App-Benachrichtigungen

2025-05-19T13:14:00+01:00

Aktuell funktionieren leider die Push-Benachrichtigungen des V2-Servers für Apple/iOS-Geräte nicht.

Das gilt für alle V2-Server-Installationen. Wir arbeiten an der Problembehebung.

Ausweichoptionen sind Push-Nachrichten via Mail (im Fahrzeug-Editor aktivierbar), oder Push-Nachrichten über Pushover (Modul: Config → Pushover).

Bitte entschuldigt die Unannehmlichkeiten, wir informieren euch, sobald das Problem behoben ist.

IPv6-Support

2024-12-27T16:31:00+01:00

https://dexters-web.de/ hat jetzt auch eine IPv6-Adresse.

Ein IPv6-fähiger Client verwendet diese idR. automatisch und vorrangig. Ob das der Fall ist kann über folgende Testseite geprüft werden:

https://dexters-web.de/test-ipv6

Hinweis: die OVMS-API-Adresse "ovms.dexters-web.de" bleibt wie bisher rein IPv4, da das Modul noch kein IPv6 unterstützt (ist auch noch nicht absehbar).

Warum IPv6?

Allgemein, weil es das IPv4-Protokoll langfristig ablösen wird.

Konkret jetzt, weil IPv4-Adressen bereits Mangelware sind, und immer mehr Provider zu einem Verfahren greifen, bei dem alle Provider-Kunden sich einen beschränkten Satz an IPv4-Adressen teilen (CGNAT).

In diesem Fall sind leider auch alle Kunden eines Providers durch IP-Sperrungen zum Schutz gegen Angriffe betroffen; Websites sind dann zeitweise aus dem gesamten Providernetz heraus nicht erreichbar.

IPv6 löst das Problem dieser "Sippenhaft", da damit wieder genügend viele Adressen verfügbar sind, so dass jeder PC wieder seine eigene Adresse erhält.

Geplante Serverwartung

2024-11-26T19:09:00+01:00

In der Nacht vom 5. auf den 6. Dezember wird der Server im Zeitfenster zwischen 23 Uhr und 1 Uhr (CET) wegen Wartungsarbeiten im Rechenzentrum unseres Providers für vorr. maximal 30 Minuten offline sein.

Leider lässt sich der Zeitpunkt nicht genauer eingrenzen, bitte plant ggf. entsprechend.

MQTT-Server

2024-05-07T13:55:00+01:00

Ab sofort stelle ich hier zusätzlich zum V2/MP-Server einen V3/MQTT-Hub bereit.

Der MQTT-Server ("Server V3" im Modul) ist derzeit als Ergänzung zum V2-Server gedacht. Er dient vorerst rein als Datendrehscheibe für MQTT-Clients. Für die Archivierung von Daten, für Push-Nachrichten, die Web-Shell etc. wird weiterhin eine aktive V2-Verbindung benötigt (diese kann aber parallel zur V3-Verbindung laufen).

Hinweis: V3/MQTT ist im Modul derzeit noch als "experimentelles Feature" eingestuft, d.h. die Funktionalität und der Datenaufbau können sich ggf. noch ändern. Das definierte Topic-Schema soweit ist auf der Entwickler-Mailingliste nachlesbar, und ein einfacher Perl-Client ist im OVMS Github-Repository herunterladbar.

Der Zugriff auf den MQTT-Server erfolgt mit dem Login des Nutzerkontos. Alle Fahrzeuge eines Nutzers können nach dem OVMS-Standard-Topicschema unter dem Nutzerlogin gemeinsam verwaltet und abgefragt werden.

Serveradresse: ovms.dexters-web.de
Ports: MQTT-Standard, d.h. 1883 unverschlüsselt / 8883 verschlüsselt (TLS)
Username & Passwort: des Haupt-Nutzerkontos hier
Topic-Präfix: OVMS-Standard, d.h. ovms/<username>/<vehicleid>/

Der Zugriff ist nur auf die eigenen Topics nach diesem Schema erlaubt.

Wichtig: bei einer Änderung des Konto-Passworts sollten alle MQTT-Clients solange pausiert werden, bis diese das neue Passwort haben. Andernfalls droht eine temporäre IP-Sperrung für Clients, die noch mit dem alten Passwort zugreifen.

Vorlage für den Aufruf des OVMS-Beispiel-Clients:

ovms_v3shell.pl --server ovms.dexters-web.de --port 8883 --tls --username '…' --password '…' --id '…'

Vorlage für Aufruf des Mosquitto-Clients mit JSON-Ausgabe:

mosquitto_sub -h ovms.dexters-web.de -p 8883 -u '…' -P '…' -t '#' -F %j

Vorlage für Ausführung eines OVMS-Kommandos (stat) mit dem Mosquitto-Client:

mosquitto_rr -h ovms.dexters-web.de -p 8883 -u '…' -P '…' \
  -t 'ovms/username/vehicleid/client/rr/command/1 \
  -e 'ovms/username/vehicleid/client/rr/response/1' \
  -m 'stat'

Serverumzug

2024-03-03T15:37:00+01:00

dexters-web.de ist soeben auf einen neuen Server umgezogen.

Das betrifft natürlich auch den OVMS-Server. Wer bislang bereits den Namen ovms.dexters-web.de statt der IP-Adresse verwendet hat, muss nichts ändern.

Wer noch mit der IP-Adresse zugreifen muss oder möchte, der muss diese auf die neue IP einstellen: 85.195.96.186

Mit der Serverumstellung habe ich auch die Android-Benachrichtigungen serverseitig auf die neue GoogleAPI (Firebase Cloud Messaging) umgestellt. Dazu passend gibt es eine neue App-Release, die ebenfalls die neue API verwendet. Die alte App wird Nachrichten nur noch bis Ende Juni erhalten, dann schaltet Google das alte API ab.

Dazu ein Hinweis: falls ihr nach dem App-Update keine Nachrichten erhaltet, startet das Gerät einmal komplett neu.

Falls irgendwelche Probleme mit dem Server auftreten bitte ich um Mitteilung.

Firmware-Release 3.3.003

2023-01-16T13:29:00+01:00

Firmware 3.3.003 ist nun in "main" verfügbar. Release 3.3.002 (03/2022) hatte ich vergessen hier zu beschreiben, daher jetzt hier mit dabei.

- Location: flatbed movement alarm only with reliable positioning
  New configs:
    [vehicle] gps.sq.good               -- SQ level for location state "reliable", default 60
