I have been testing with MQTT-Explorer and Cerbo.
When i started it, it workt great. I saw a lot of information.
Now subbenly it only shows serial number.
I have stopped and started the MQTT server on cerbo, restarted cerbo and updated cerbo, started MQTT-Explorer on differend pc but nothing helpt.
I saw others having the same problem getting adviced to start some kind of hardbeat. But i use MQTT-Explorer (only testing and looking at this moment ) witch takes care of this hardbeat.
I like to read this data later (via ESP8266) to use it in my own program.
But i can not find out why it is no longer showing all the data.
After several days of testing i am at a total loss.
I use: MQTT-Explorer-0.4.0-beta.6.
Advaved tab in MQTT-Explorer had there entries: “#” and “$SYS#” (the defauld, that has workt).
Can anyone help?

Have you sent it a keep alive?
If you open VRM you may find it starts to work, which means no keep alive has been sent as per the docs.

Hi,
I’m not connecting to the vrm with mqtt ecplorer. I connect to the cerbo.
Anyway, vrm via browser is always open here.
Or did i understand you wrong here?

Also, even if mqtt does not send keep alives, shouldn’t it display all the values until timeout?
And remember, it workt for a day or so.

If you open vrm it will send a keep alive while the browser is open.
If local mqtt explorer starts to work, you have forgotten to send a keep alive.

UPDATE:
I turns out i was confusing the browser connection to my cerbo and a connection to the victron vrm site.
When i open the vrm site in a browser the mqtt starts to work.
This leaves me with two questions:

  • why must i have a connection to vrm when i connect to the cerbo mqtt?
  • i like to be able to read all data even when internet is down. If i need a constand vrm window open does this mean that when my internet is down, i can no longer read the data from the cerbo?
