Glad to hear you sorted it out! For future reference, it may take up to an hour for new data keys to show up in Saillogger. This is only applicable for the initial configuration, once done data flows in regular one minute intervals.

@admin Thank you for the work!!!

This was resolved in a different thread. Upgrading to the latest Victron firmware and installing Saillogger plugin 4.2.1 or later will work.

Hmm, spotty access point should not cause this. It is almost always due to GPS. Please keep monitoring and let us know if you observe anything else that is unusual.

@jonnys , we have been investigating this and it turns out this is an issue in the latest version of VenusOS v3.62, please see the following post for details and potential workarounds:

IMPORTANT NOTE: This issue has been resolved in Saillogger Signal K plugin version 4.2.1. In collaboration with Victron, we identified the root cause and fix...

Thank you for sharing this Alastair.

It looks correct, we plan for more improvements for this logbook, so stay tuned.

Ok, please try two things:

Check the interface name on Signal K for the CAN interface, if it is can0 or vecan0, please try vecan1. Make sure to restart it after you make a change. See if you can connect it to first port (even temporarily) and if it makes any difference.

Independently, the first port is galvanically isolated, the second one is not. For NMEA connection, Victron's strong recommendation is to use the first port.

Is Victron GX connected to NMEA 2000? You need a special cable for that (you could also make your own, see this article)

If you verified the connection, make sure your GPS source is turned on (it might be the chartplotter).

When everything is working you should be able to go to Signal K Data Browser and search for navigation.position and it should show your current position.

If you haven't already, do check this tutorial, it explains though:

One more thought, please make sure the times on Cerbo GX and your Chartplotter are in sync and set to the same timezone (including daylight savings). If there is a time mismatch between the two, it could lead to problems like this.

Hi @SV-UNSInn there was a bug with RPMs, we just fixed it. It should work now.

We also added a new type of "Duration", which will convert seconds to hours. You can use it for engine hours.

Happy Saillogging!

Unfortunately this is an annoying Signal K bug. AIS data may override the boat name in some edge cases. It happens more frequently if you happen to have a DataHub but we have seen it happening without a DataHub too.

Signal K team has been working on a fix, here is a link to the tracker: https://github.com/SignalK/signalk-server/pull/1833

In the meantime, restarting Signal K should solve it.

Yes, perfect!

Hi,
thanks for your immediate response ... highly appreciated. When reading your advice, it popped up that I already had once the same problem and it was and still is hökens-anchor-alarm https://www.npmjs.com/package/hoekens-anchor-alarm after deleting the anchor-alarm everything is back to normal. Thank you.

Perfect. Thanks!

Here is an example of how additional data is captured per trip, from our logbook:

This will show up for you the next time you complete a trip, based on custom monitoring data you have added.

Thank you so much.
I'll try that.
