Shunts that support SignalK?

I have used Pico2SignalK for 2 seasons, but sometime this spring Simarine have changed something and broken the integration. I'm looking for some other shunts that can be connected to SignalK? Any tips?

filter duplicates out for outbound connections

I have a problem with my NMEA 0183 multiplexer where several devices are repeating values but calculating them slightly differently. This causes displays to jump around. I would like to come up with a way to use Signalk to provide a single filtered stream over both tcp and serial and have devices use these connections instead of the multiplexer outputs. This way the multiplexer is only responsible for the inputs and signalk is providing the input for all devices

signal k appstore thinks its offline all of a sudden

Hi! Pi 3 has been running with opencpn and signalk for about 18months now with node red pushing data into boat(home)assistant. It’s been working flawlessly until last week. So I started trying to debug and signalk AppStore thinks it is offline saying: Appstore not available...

Can I change the width of the instruments in Freeboard?

I would like to use less screen width for the instruments, or even better, have them as a row at the bottom instead of as a column to the right. I have not found any place in Freeboard to change that. Is that because I'm bad at looking for it, or is it because it isn't possible?

Wasn't it possible to "Save as" in Instrumentpanel before?

Simply that. I was sure I could save layouts from the same account under different names (for different devices) before, but I can't seem to find that option now. Is it a change, or is it me?

Trouble connecting to my seayak

Hi, I'm new to signal K. Sorry if this is a basic question. I'm trying to setup a NEMA0183 data connection to my yakbitz seayak. I pasted a screenshot of my config, looks ok but for some reason I dont get any data. I know that my pi can receive the data, running a netcat command works (see screenshot 2). And if paste my data inside the Data fiddler it is able to decode it, so the data format looks ok....

Publishing to the app store

Hi All, I am new to NPM, so not sure if I have done this correctly but is there a delay from publishing to seeing a plugin in the app store?

Random changes in boat name

One of Saillogger users is experiencing a very weird problem. The boat name keeps changing randomly, seemingly picking up names from neighboring AIS targets (advertised by a PredictWind DataHub back to N2k from what I understand). The name in "Server -> Settings" is persistent and is right, however when they look at "Data Browser", they see a different name and oddly enough that name keeps changing. Never seen anything like this before and not having direct access to the Signal K instance, struggling a bit to troubleshoot. Is this ringing a bell for anyone? Is there any flow where a name can be overriden by a network value?...

Design question

My setup is a boat with NMEA 0183 & 2000. SK server is running on a Pi 4B, and a smaller Pi running VenusOS. I have a couple of Halmets that will gather data from engines, fuel tanks and water tanks. I also have a Hatlabs SH-GW. I've just started with Node Red, dashboards seem fairly straight forward.
Question 1: Is it better to have any/all data sent as N2K from the Halmets/ESP32s, or have it all sent as SignalK and then decide what i want to expose to the N2K network via the SK plugin? Question2: I have an InfluxDB on the Pi 4, is it more efficient/better to get the SignalK plugin to write to the InfluxDB, or to get Node Red to perform this task??...

naivegpxlogger does not write gpx-files

Hi @Владимир Калачихин , to write some tracks as gpx I just tested your plugin naivegpxlogger. I entered an absolute path (with a trailing /) where the gpx files should be stored. Here a screenshot of my configuration....

Anchor alarm: typo in bow height property, no depth saved?

I have started using Anchor Alarm plugin and have noticed two things: 1. design.bowAnchorHight is probably typo for Height? 2. It seems that depth is not stored at Drop anchor. Would be useful to have together with position to be show in UI.v Also, I have four GPS sources on the boat: 2x plotter, AIS and USB GPS in Cerbo. Only Cerbo is on during night as N2K network is off. I suspect, gps position is not enough to calculate heading and show how the boat is oriented, right? Maybe the UI should rotate the boat on screen to point to anchor position (most likely direction)? And thanks to all SignalK developers, I am so glad to found it on my Cerbo and I am now exporing endless opportunities it provides....

ZigBee Devices

We have a ZigBee USB dongle and several Zigbee sensors sitting unused in a drawer. Is there a way to integrate these devices into Signalk?

Is it possible to get maps in an easier way than MapBox?

I tried to make a small map of my area at the tip of Norway, from Kristiansand to Lyngdal (which is as far as I can imagine going even when I retire in a few years) on MapBox, but I gotta admit that I gave up. The learning curve is steep. I wanted to use TukTuk in SignalK to have an extra, fully offline map available on the phone/tablet in addition to the one on the Garmin 720 in the (open) wheelhouse, to know exactly where the depth changes are when setting crawfish and crab pots. But is there...

Hi all

I'm considering buying the Victron "BMV-712 SMART" to replace my old BMV (before Victron era). I have the hole in my panel and it looks like a drop-in-replacement. Can anyone share some experience? Do someone have an BMV-712 connected to SignalK? I have read the thread here on Victron BLE connections and (although a little fiddly) I think I can get the connection to happen. Victron seems to be good at support and their interest in SignalK is exemplary that is why i want their products....

What's the sudo password for the Docker container?

I would like to try to ping the 192.168.3.2 from the Docker image of SK, but I can't install ping utils because I need the sudo password. Can somebody please tell me what that is?

inject data?

What's the simplest way to inject navigation.magneticVariation into the SK data stream (so Derived Data can calculate true heading from magnetic heading)? It is OK if it's a constant; I can change it once a year.

Garmin Quatix - is it possible to integrate without Garmin infrastructure?

I just won a Quatix 7 watch and honestly don't know what to do with it as I run SignalK and B&G. Anyone integrated it without other garmin compnents?
