  Wrong boat name
  A admin

  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.

  Engine data in logs?
  A admin

  You can certainly use them with custom monitoring, anything in NMEA2k/Signal K can be monitored with Saillogger.

  That said, we are working on a much more integrated experience (imagine engine hours being part of your trip logs by default), but it is probably a couple of months out. First we need to install one on our boat and that will probably happen around June.

  Monitoring sources are gone
  A admin

  Hi Otto,

  This is a bit strange, as long as there is a single active monitoring device, where the data is sourced should not matter.

  Can you check a few things:

  1. First ensure that there is no older device or something else configured with the same collector ID. Multiple devices sending data simultaneously will cause problems.
  2. Reboot the Raspberry Pi if you haven't already and wait for 15 minutes to see if the labels in Saillogger or data is changing. Try to reconfigure the monitoring parameters on Saillogger at this point.
  3. If still doesn't work, it would help to delete the local cache on Signal K. It is unlikely but it might have been corrupted in a hard reset. Here is how it should look like on Venus OS (I haven't tried this on a Raspberry Pi running Venus OS but should be similar)

  • Stop Signal K process (Toggle off Signal K in Venus OS menu) - This is important
  • SSH into Venus OS
  • Delete the local cache by /data/conf/signalk/plugin-config-data/signalk-saillogger/saillogger_v2.sqlite3
  • Start Signal K process

  4. If it is still not working, the best is to reinstall Signal K from scratch, here is how it would look like on Venus OS (I haven't tried this on a Raspberry Pi running Venus OS but should be similar):

  • 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 rm -rf /data/conf/signalk
  • Start Signal K process
  • You will need to download the Signal K plugin again and configure it.

  Note that options 3 and 4 can be dangerous in that they may corrupt Venus OS and/or Signal K.

  Good luck and keep us posted on what you find.

  Moorage granularity in a harbor with many marinas and an anchorage
  A admin

  Hi Jim, yes you can change it per Stay. There is default stay type for a given moorage and it is assigned to all stays there but then you can go ahead and customize each stay as you wish. Go to https://saillogger.com/stays/ and adjust the "Stayed At" drop-down as needed.

  Addtional Monitoring Codes
  A admin

  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.

  Curious if there is a confusion. In regards to wind average/max and SOG average/max, they are already part of each trip log. Here is an example:

  

  Bottom two sections have those.

  When you add additional monitoring data, minimum and maximum of those values will also be captured and displayed per log (under a section called Additional Data). Average is a bit more contextual and only makes sense for few types, so these are minimum and maximum right now.

  Strangely COG, TWD and AWA are displayed as knots.

  You should use the same unit per monitoring block and choose the monitoring type accordingly. So instead of a single "Sailing Performance Data", you could have multiple blocks. All values in a single block will share the same unit.

  Addtional Monitoring Codes

  I was about to say that, more stateful things like average and maximum are not normally transmitted on NMEA, I don't believe they have PGNs either. Saillogger definitely calculates the averages and max and gives it as part of a trip/log summary but from what I understand you want to display that during the trip itself? If so, while doable, they are not currently calculated during a trip.

  Addtional Monitoring Codes

  Re-read your message, if this doesn't work, let's focus on one specific item first.

  Make sure that field is available in N2k first, then make sure it shows up in the Data Browser for Signal K. If those happen but the path doesn't show up in Saillogger, restart Signal K and wait 10 minutes.

  Please share your findings and we can try to help you more.

  Hi Brian, we published a detailed tutorial for this: Saillogger NMEA 2000 Monitoring

  In a nutshell:

  Step 1: Find the Signal K path of the N2k data you want to monitor

  Step 2: Add a custom monitoring section in Saillogger to monitor it. Ensure you choose the right type so Saillogger can do the necessary unit conversions for you (to degrees, knots, miles, meters/feet etc.)
