Hi Thomas, it is indeed what is mentioned in the FAQ. It takes an hour to finalize a trip, so if you turn on your Raspberry Pi for just a few minutes, it will autocomplete. Alternatively, keep the Raspberry Pi on a bit longer after you complete your trip.

Hi @TargaDriver and @Voodoo, thank you both for the suggestion.

We understand the desire for more granular tracking in certain situations. That said, a key part of Saillogger’s design is full automation, sampling frequency is part of the core logic and is dynamically adjusted based on context.

That said, we recently deployed updates to improve how frequency adapts, including better handling of maneuvers beyond just speed changes. Let us know how it helps you. We’ll also log a ticket to explore additional enhancements, such as incorporating vectored charts to help Saillogger recognize when maneuvering occurs near islands, ports, channels, and other complex areas.

Hi Brian, thanks for the note.

There’s no direct way to link a missing track, but we may be able to help. Have you added any monitoring logs since the last missing segment that’s covered by the GPX file? If not, please send us the file and we’ll see if we can import it for you.

If you’ve already logged anything since that missing segment, unfortunately this won’t be possible, as Saillogger’s state will have changed and will require deep surgery to import that track.

Hi Brian, replied over e-mail but I suspect Venus 3.63 upgrade will not help as Signal K configuration is persisted across upgrades. There is no harm to try though.

Hi @SV_Atlas, a factory reset should be the last resort. First, try a clean install of Signal K—step‑by‑step instructions are in this post: https://community.saillogger.com/topic/111/new-install-wont-start/2?_=1753236272577

Let us know if that doesn’t resolve the issue or if you need help with any of the steps

Hi John, I thought we had addressed this as part of this thread. Isn't it working as expected?

In general, if you are moving fast, the granularity is automatically adjusted and can be as high as every minute.

Hi @wrwakefield ,toggling Signal K on or off doesn't delete the Signal K configuration. We haven't explicitly tested the factory reset but pretty sure it would wipe out Signal K configuration as well.

We regularly delete the Signal K config to test out things from scratch, it has never caused an issue but of course operating on the CLI requires diligence. Just make sure "Signal K" toggle is off before you delete that directory. I don't think it is a showstopper if you don't but it is safer to do so.

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.

@wrwakefield, sorry to hear the problems you encountered. v3.62 and Saillogger Plugin 4.2.1 should work alongside other plugins, we also use v3.62 ourselves and run many additional plugins beyond Saillogger. It’s possible that Signal K became corrupted in the process; have you tried restarting the Cerbo GX completely? If you did and it didn’t work, completely removing it and re-configuring may be the best thing to do.

This will require root access to Cerbo GX though. Instructions are here but please read the warnings carefully.

Please follow these steps after obtaining root access:

• Stop Signal K process (Toggle off Signal K in Venus OS menu) - This is important
• SSH into Venus OS
• Delete the Signal K directory by issuing the command rm -rf /data/conf/signalk
• Exit ssh by exit or closing the terminal
• Start Signal K process

This will give you a fresh, brand new Signal K instance. That also means all your previous configuration will be lost. You will need to download the Signal K plugin again and configure it. Make sure you wait long enough for installing the plugin and do not interrupt it. It can take longer than 30 minutes.

Let us know if this helps.

Hi @svcatalyst — Saillogger doesn’t perform any NMEA or PGN decoding; all of that happens in Signal K, and SailLogger uses the information once it’s already decoded. So the real question is whether Signal K supports this PGN. Because you don’t see it in Data Browser, it appears it doesn’t support it, and unfortunately that’s beyond our control.

Hi @ilederey we tried hard to clean it but looks like it got pretty garbled with a lot of back and forth zigzags, unfortunately we couldn't recover it.

Hi @svcatalyst,

We’re not very familiar with the Yacht Devices Run Indicator. Do you know if its data can be brought into Signal K? It doesn’t have to go through NMEA; any method that gets the data into Signal K would be sufficient. However, getting it into Signal K—whether via NMEA messages or a dedicated Signal K plugin—is a prerequisite for monitoring it on Saillogger.

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

No, you cannot do it easily without going to CLI

Can you upgrade to 3.62 and try again?

@Andrea this should just work without problems with plugin 4.2.1, did you encounter any issues?

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.

You can definitely delete them, click on the log name and you see a "delete log" option at the bottom of the information panel on the left.

Question is, why these come up though? Is there an erratic GPS on the boat?

@jonnys This issue has been resolved in Saillogger Signal K plugin version 4.2.1. In collaboration with Victron, we fixed it by rebuilding the dependency in a different way. Please install Signal K Saillogger plugin version 4.2.1 and let us see if you see any issues.

Thanks, @Gerler. It turns out the problem is specific to the latest Venus OS (v3.62). Appreciate you uncovering the workaround! We’re coordinating with Victron on a permanent fix. In the meantime, we’ve posted the details here:

FIXED: Saillogger plugin fails to install on Venus OS v3.62

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...
