Hello, After installing VenusOS v3.64, my Node Red flows signal an error: “Not connected to dbus”. This message is only shown with change-setting-nodes, not with query-nodes. At first all seems ok, but after a short period of time (guess: 10-20 seconds) the error appears. Restarting the Cerbo did…

Hey all, this is fixed per Venus OS v3.70~27. Would be great if you can confirm that its fixed for you as well. Thank you for the help and reports!

With v3.70~27 I can confirm that my flows had zero problems. Within 1-2 seconds after deploying all bits started flowing, even after multiple deploys. Thanks for the fix and happy to help.

with 3.70-27 I still have issues with the Victron EVCS (ns) [image]

Venus OS v3.70~27 installed. So far, so good! :+1: Thanks! :smiley:

No it did not. What helped was a reboot from the EVCS. I’ll keep watching it.

Slightly offtopic: I reverted back to v3.63 because, running v3.70~27, I wasn’t able to modify /etc/watchdog.conf anymore. Without this modification, the Cerbo reboots every hour or so.

Do you have “Reboot device when no contact” enabled by any chance? As that will cause the GX to reboot if it loses the connection with VRM for more than an hour. [image]

No, I haven’t. Also, the file /var/log/watchdog_processlist.txt shows that watchdog reset thresholds were reached. The last modified timestamp of the file tells me when this happened. With the default paramters for the watchdog, it happens every two hours or so. Changing /etc/watchdog.conf (max-load…

Ah, the max-load parameters indicate how high the system load can be over a specific timeframe. For reference: a load higher than 1 means the system is (temporarily) overloaded. A long-running load of 5 or more usually indicates that something on your system is using an excessive amount of resourc…
