Question regarding Freeboard

Hi, Wind gauge has a strange delay when using the "instruments" within Freeboard. The data is available but does not show until like a minute has passed. ...

Multiple session on N2K?

SignalK set up to send data to my B&G setup for the performance plugin by @HansT. When I reboot, this happens more often than not. How do I avoid?

How does source priority work?

Our network is a bit crowded with sources. Several GPS and heading sources as well as sources that repeat received data. For example, we have a Vesper Cortex and a YD Ethernet gateway that repeats (over Ethernet) NMEA data in addition to the B&G Zeus. I have all of these data connections going in to SK because they all don't provide the same data. For example, the Zeus and Vesper don't forward the engine data. I have the Vesper connected because it forwards GPS and AIS data when at anchor and the NMEA network is powered off. I've found that this causes weird issues with all this multiple sources so I've started using source priority. ...

B&G Performance Plugin

Hi @HansT. I've been messing around with your plugins and trying to get them to work. (Lately too much time spent doing actual sailing though...) Last week when racing I noticed that my B&G countdown race timer didn't work. It ticked down one second and then stopped. I tried all the B&G settings and wondered if I might have caused it by using other than the default 5 min count down, but no results there. Not only until I ran my B&G plotters/triton without signalK did I get a working countdown. I...

What do yellow vessel names mean in Freeboard?

Some vessels' names show up yellow on the map. What does that mean?

Multiplexing Seatalk

Does signal k have a means of outputting Seatalk on a GPIO port (as it is able to take it in)? Or would I need some form of nmea0183 to Seatalk converter?

Restart Signalk when can01 is "lost"

Is it possible to trigger an restart of the signalk service when a connection is lost? i.e. no data is recieved as in the screenshot? The reason being is that after the can01 is lost, the derived-data plugin continues to calculate incorrect values, based on latest measurments from the can01 (along with other gps data?). See screenshot for forther details. Restart the service will stop the derived-data from computing. Thanks!...

canName question. Is there a way to relate the canName to a human readable name?

I'd like to be able to identify different sources to set priority.

No SignalK on N2K

Installed new Vulcan plotters and did some general maintenance. Now I can't get signlk data to my plotters. I do get nmea data on my signalk server and the candump is humming and spinning like a cat. Signalk used to be available in my device list on my old plotter, but not now. Even after a refresh. Any ideas about where to start troubleshooting?...

How to setup an NMEA0183 OUT with NMEA2000 on can0

Hi, I want to send my deep and speed datas from the NMEA2000 to an NMEA0183 Output port. Do I need to add can0 in the OUTPUT EVENTS field? What do I need to configured in the Plugins SIGNALK to NMEA0138 and MNEA2000?...

Distributed Signal K (New User)

Good afternoon! Can I install multiple SignalK instances aboard, and have them communicate/merge data over the TCP/IP network? My idea is that I would have a Raspi Zero 2 W at my NMEA/Seatalk bridge, and then run Signal K on a Raspi 4b somewhere else. Is this how SignalK works? Or is it more a system built around a single primary host? Is there a way to multiplex data?...

Generate Notification from "True" "False"

I have bilge sensors cross my boat using sensesp. Amongst other things they return a "true" or "false" of the state of a float switch. I have these displayed on a KIP dashboard. However last weekend I had a bolt failure on my saildrive that resulted in a minor leak. I realised I would really like to know about this more quickly in future. I have played with various plugins that generate notifications such as "Zones" but these all work with numeric values and not boolean values. Does anyone know of a plugin that can generate a notification from an existing path that is boolean please? Thanks...

sk-to-nmea2000: Battery state of charge missing on n2k side?

I collect battery data via the victron plugin and have voltages, current, state of charge available in sk. I want to display this data on n2k devices (Raymarine a67 plotter, i70s display.). In the plugin sk-to-nmea2000 I configured my battery instances 0 and 1, as intended I then see voltages and currents on my nmea2000 devices. But state of charge does not show up. As a workaround I also mapped battery state of charge to the tank level of a "dummy tank" and configured this tank in sk-to-nmea2000. Then I can see battery state of charge as tank level on my n2k devices. What can be the problem, that I am not able to directly send battery state of charge to n2k?...

How to send PGN from SK?

node-red to signal K for 4G RSSI from router

My next project is to try and get the onboard 4g signal strength to show on a kip dashboard. Hoping to have node-red ping the onboard router (via ssh) to get the below response. Parse it to json format and extract the rssi before injecting into signalk format. Anyone done this or got any tips?...

signalk-server / signalk-openweather-plugin / no connection to openweather

How do I enable more debugging information in SK Server?

I am transmitting a PGN (leeway) on the bus. I can see it in the list of PGNs but it doesn't show up under a path. I have probably set a field incorrectly. I would like to determine why it's being dropped. I see it in the log for the bus but not in the server logs. I have tried guessing a few likely settings in server logging but no luck so far.

Why do I have two different speeds over ground?

See this screenshot. I have an em-trak AIS connected over USB and no other devices. Why does Signal K receive two different speeds? What do the words AIS.AI and AIS.GN mean?

Is there an app to feed an Android device location data from Signal K?

I have an Amazon Fire tablet onboard, and it lacks its own GPS chip, so regular map apps can't show the device's location. I could write an Android app that polls Signal K or listens for NMEA messages on the wifi and sets device's location from that (with developer mode on to allow GPS spoofing), but before I do, maybe this exists already?
