Saillogger Community

Like many sailors, I'm very careful to use the engine as little as possible, even when the wind is light (like in the Mediterranean Sea) or coming from the wrong direction compared to my destination. This is why I was one of the users who asked to be able to see the percentage of the route sailed versus the portion under power in the trip reports. I'd like to ask the developers, if possible, to color the portion of the route sailed differently from the portion under power, so I can immediately get a sense of the results. Would this be possible?

@admin Now that explains everything. Thanks.

Hi Admin, thanks for the reply. Something strange happened in my experience. When I took the boat to the shipyard for dry docking, I turned off the instruments (N2K). Since the Saillogger plugin runs on SK server on VenusOs on CerboGX, and that remained active and powered, I expected the data relating to the service and starter batteries to arrive on Saillogger. Instead, everything froze. I tried restarting SK server several times and checked that the Saillogger plugin was working properly on the iOS application, or that the Saillogger web app was not updating the battery voltage data.
Once the boat was picked up from the shipyard and the instruments were turned on, everything worked again.

@admin I configured another "engine hours" data item, taking the same variable from SK, namely "Propulsion.Port.runTime." In fact, I now have two in my configuration. Both now work; even the one that wasn't previously recording data on the graph now records values ​​over time. I can say that the problem is solved. Thanks.

Thanks for the reply, I'm copying the screenshot of the configuration which, as I explained before, works when the engine is on, in the sense that if I look in the iPhone application on the monitor page, the one with the instrument symbol, I see the number of hours the engine has been running , so I think the configuration is correct?
It just seems like it's not recording that parameter

Hi, I've already started a similar thread but haven't gotten a response. I'd like to be able to record the number of engine hours at the start and end of a trip in additional data. The data is available on SK (Propulsion.Port.runTime) and is accepted by Saillogger (I see it from the app while the engine is running) , but it isn't recorded at any point during the trip. I also read another parameter from the engine which is the RPM and that is recorded regularly. Any idea how to fix this? Thanks.

With the data recorded by the application and without having to add any more, it would be possible to have the polar sail diagram of your boat created and continuously updated. That would be fantastic.

@admin Hi Admin, today I was able to go out by boat and I was able to verify that in the trip the number of engine hours was not recorded and I don't understand why, the RPMs are recorded as long as the engine is running of course and instead the pre-engines are not

@admin Let me explain better, the PGN that indicates the hours of use of the engine is shown in Saillogger as soon as I turn on the engine because the interface between the engine and N2K turns on together with the engine. So I should see it recorded in the travellers like the PGN RPM that in the same way comes from the same interface
In the last trip I made it was not recorded
This morning I tried to start the engine and the number of hours of movement carried out by the engine appeared in Saillogger sign that the PGN is read
I hope I have clarified better ?

There is, however, another aspect to consider regarding the data coming from the engine through an interface, for example, YDEG-04, which does not output any data when the engine is off. In this case, on Saillogger, in the N2K parameter monitoring settings fields, the parameter disappears and a blank field is shown. I must say, however, that, at least in the case of RPM, when the engine is restarted, Saillogger starts monitoring the parameter again (at least in my case). This should also happen with the parameter that shows the total engine hours "propulsion.port.runTime" but unfortunately on my last trip it didn't happen and I can't understand why. I say this because this feature is the basis of my desire to know for each trip how many hours of sailing I did and how many of engine.

You're absolutely right (as always), admin. There's a plugin on SK that allows you to send Smart Battery Sense data to SK and therefore to Saillogger. It seems this plugin has crashed. I've now restarted SK and updated VenusOS, and the plugin is back up and running; I can see it on Saillogger. It seems this also happened to the Yachtdevice Yanmar engine interface, YDEG-04, but it only works when the engine is running, so I think it was more of a SK issue. In fact, I can't see the YDEG-04 PGNs now, since the engine is off.

Thanks Admin for the reply, it actually seems as you say, all the "propulsion" data have a timestamp of 9/8 as well as the "propulsion.port.revolutions" data which was recorded at every point of the last trip. The same goes for the "electrical.batteries.starter.voltage" data which has a timestamp of 9/5 which reports a value in Volts that is changing over time due to the self-discharge of the starter battery. However, I can confirm that if I look at parameters such as the wind "environment.wind.speedApparent" I see that the "timestamp" is alive and updating second by second. While I can understand that the data coming from the engine's N2K interface is frozen as a value on last Sunday 7/9 when I turned off the engine, I can't understand the timestamp dating back to 9/8? Even less can I understand the Bluetooth transducer that measures the voltage of the engine's starter battery, which has a value that decreases every day by a few tenths of a volt and has a timestamp dating back to 9/5. Can you help me? Thanks.

Hello everyone, I've honestly already reported this problem (in my case) in another post, but I'd like to bring it up again in the hope that it can be resolved. Basically, some PGNs on my SK server aren't displayed after selecting them in Saillogger settings; the displayed value is zero. Yet, in the SK server data browser, the PGN is displayed with a value, but it's as if Saillogger, although it finds the parameter in the list of available parameters, isn't able to set it and display it. I'll leave some examples in screenshots. Thanks.

@admin Hello admin, I entered in the data to be recorded what you suggested and in fact when I started the engine this parameter showed the total running hours of the engine. Unfortunately, however, this data has not been recorded in the path data as per the attached screenshot, although the data is present on the SK server and is available among those shown on Saillogger

@admin I don't remember seeing this pgn among those that my Yanmar to N2K interface provides me but I'll check, however I saw the data of the engine hours expressed in seconds, I could record that and make the delta between the first reading and the last reading and then multiply it by 3600 and obtain the hours, what do you think?

@admin Thanks for the reply, I'm sure it will be great when this is available. Right now, how can I determine how much of a trip was under engine? I connected the RPM data from SK and I see it for every trip, but I don't have a sum of the engine usage time between the times when I was sailing and the times when I was under engine. Is there a way to do it now?
Furthermore, also as a test bench, I tried to connect the SK Fuel Rate data which is expressed in m3/h but I did not find a type of representation given that could read it, I have speed volume etc but not a ratio such as volume/time
