Ok, your logs should be imported now. Your latest position might be off due to this import. If you bring up your Cerbo and wait for 10 minutes or so, this should all sort itself out. If not, try restarting Signal K.

PredictWind Track? -
Cumulative Track?Hi, thank you for the suggestion. The closest you can have for this is through timelapse: https://saillogger.com/svatlas/timelapse?speed=0
Having a toggle in the monitoring page is a good idea though, let us look into it!

PredictWind Track?Hi there,
You can use PredictWind or a Victron device (also a Raspberry Pi) for monitoring. Previously captured PredictWind tracks can also be imported. However, only one monitoring source should be used at the same time otherwise there will potentially be duplicate entries.
If you share your PredictWind tracker link with us, and are ok to clean up some duplicate entries (the ones that you have been created after you started using Saillogger that PredictWind also captured will potentially be captured twice), we can do the import for you!

Max Speed? Max TWS? Max AWS? Mileage run?Hi there, thank you for the recommendation!
While underway in a long passage that takes more than 24 hours, some of these are sent as a daily summary e-mail, though they are not available on the monitoring page. They can be added but the concern would be a more cluttered UI. We care about a UI that is as simple and intuitive as possible.
Let us work with our design team to see what options we can have here to balance more info with a clean interface. Thanks againfor the suggestion!

True vs Apparent Wind SpeedHi there,
For true wind speed and direction, you should toggle the following option on in the
derived-data
plugin:True Wind Angle, Direction and Speed
In order to calculate true wind values, the following are required:
navigation.headingTrue
navigation.speedThroughWater
environment.wind.speedApparent
environment.wind.angleApparent
speedThroughWater
should be coming from your speedometer, and when anchored, it will be zero, so no problems there.speedApparent
andangleApparent
come through wind instrument and should be fine too.headingTrue
is the tricky one, it normally comes through the heading sensor which is normally linked to autopilot but depending on your instruments, it may be sourced from elsewhere too. If you don't have all of these,derived-data
will not be able to calculate the true wind readings.You can see which ones are available in the data browser.
Good luck and happy Saillogging!

Do I have to do something special when I return home after a trip?You can plugin a USB based GPS to your monitoring device. Depending on what it is, it will require a configuration like gpsd, which may require you to do some tweaking.

Do I have to do something special when I return home after a trip?Hi Michael, everything is automated, so you do not need to do anything to finish a trip. However GPS readings are required to conclude a trip or monitoring to function.
More specifically on your questions:
-
You do need a GPS source for monitoring function as it relies on your position. Keeping an MFD on would be an obvious overkill though. Do you have any other GPS source like an AIS transceiver? Alternatively, you can just add a puck GPS to your monitoring device as a backup. Or if you have Starlink, we have a plugin to use it as a backup GPS source too.
-
You do not need to do anything to close the trip. It is all automated. The moment you turn on you MFD, Saillogger will conclude the trip has completed and will close it out automatically.
-
It is an hour after you finish your trip and yes it does depend on the GPS. This is important because Saillogger avoids short stops to get gas etc.

Change home port?Hi Michael, it is set through the moorage details page. Go to the mooring details page of the port you want to designate and you will find a "Home" checkbox.

Import Logs from other servicesHi there, we do support import from some services like PredictWind. Normally this will depend availability of raw and granular data (like position records captured over regular intervals). Do you have something like that or is export an option from Postgsail?

Depth transducer offset?Hi, yes, this is configurable from the Signal K plugin. Go to plugin configuration, and change the value under
Monitoring data source for depth
.Sounds like you want to use
environment.depth.belowSurface
, make sure it is available in the Data Browser.Save the configuration and restart Signal K for the changes to take effect and all should be good!
