CCGX - keine MQTT Werte vom Wechselrichter *** CCGX no mqtt values since update

Hallo,

auf meiner Arbeit haben wir 4 ColorControl GX in den Fahrzeugen oder Anhängern installiert. Den Status der Wechselrichter, Batteriestand, Tankinhalt etc. lese ich über MQTT mittels einer Monitoring Software (PRTG) aus. Auf allen Geräten ist die automatische Firmwareupdate-Funktion aktiviert und die Firmware 2.8 ist installiert.

Seit dem 1.2.22 zwischen 3:35 und 3:55 Uhr bekomme ich von allen Geräten keine Werte mehr.

Der MQTT Explorer kann sich noch mit der CCGX verbinden, es kommen aber keine Werte der AC/DC-Technik.

Was hat sich seit dem Update verändert? Wie kann ich das wieder zum laufen bekommen? Vielen Dank für eure Hilfe.


Gruß aus Hamburg

Since 1.2.22 between 3:35 and 3:55 I don't get any values from all devices.

The MQTT Explorer can still connect to the CCGX, but no values come from the AC/DC technology.

What has changed since the update? How can I get this to work again? Many thanks for your help.

Ich würde zunächst versuchen die FW wieder auf die vorherige Version zurück zusetzen um zu schauen ob es wirklich daran liegt.
Das geht über das Update Menü, da kann man zurück auf die letzte Version gehen.

Falls das das Problem beheben sollte, würde ich empfehlen das automatische Update zu deaktivieren um so etwas in Zukunft zu vermeiden.
Neue Updates dann am besten immer erst auf einem System testen.

Im Changelog (zu finden auf https://professional.victronenergy.com/) steht zwar nicht direktes zu MQTT, aber das Update ist so umfangreich, da könnte sich evtl. auch noch ein Fehler eingeschlichen haben.

Ich habe ebenfalls das Problem, dass keine Werte mehr über MQTT gepublished werden.

Zurück zur Version 2.73 hat das Problem behoben. Daher gehe ich davon aus, dass tatsächlich ein Bug in der 2.80 besteht.

Keine Ahnung ob das etwas damit zu tun hat:
https://community.victronenergy.com/questions/118710/venus-os-v280-breaks-modbus-tcp-register-777-pv-cu.html
Kenne mich damit zu wenig aus.

Habe das Problem mal in die Entwickler weitergeleitet.

I had also problems to receive data from VRM using MQTT (own python-scripts) after upgrading to v2.80. I have been using client.publish("R/xxx/system/0/serial") as keep-alive for a long time but my problem was solved by changing keep-alive to client.publish("R/xxx/keepalive").

Hi @PeB , while checking if we could reproduce the issue, we found one thing that can explain what you saw:

In the old code ANYTHING would trigger a keepalive. Even a malformed request. In the new code... it has to be a well formed Serial read. Anybody relying on the looser handling will find that their code needs sharpening up.

I’ll add that to the change log. We’re still checking, but so far all MQTT works well; also from inverter data. So not sure what the issue of @Stefan_from_Hamburg is either.

I am facing the same issue with 2.8 and 2.84.

In the local mqtt i only see the serial, but no values of my meter?

(So far i only installed VenusOS on Raspberry and connected a EM24 via RS485, nothing else)

After downgrade to 2.73 still only the serial on local plaintext mqtt.

Is there a possibility to access the local mqtt (without internet) with credentials.

I already added a bridge to my home assistant, but only receive the serial number and no grid values

Same after fresh installation of 2.73, any idea?

Is it because i have no inverter connected, or do i need to connect with SSL?
