SignalK to Node Red

Hi, I'm struggling with Node Red (apologies if I'm in the wrong place to post this). When I connect a TCP IN node and debug, I'm not getting a stream of PGNs but rather a single message. Can anyone point me in the right direction. I can see PGNs about output via plugin signalk-to-nmea-2000

Minimum hardware requirements?

Wondering if anyone has run into performance issues with SignalK and if so what hardware it is running on? I think I've seen some discussion of performance issues from way too many AIS targets nearby? (I am not personally, I'm just curious about the resource usage and how simple/low power of a server could handle running things well)

Socketcan Error after latest Update

Hi everyone. After installing the latest Update unfortunately our SignalK-Server crashed and we had to restore an older backup. After getting the backup working again, we succesfully could install the update but now don't get anymore data over the Canbus from the Raspberry Pi. There is an error printed out, saying the "socketcan" module can't be found. It seems weird, as we didn't work anything on this packages....

Define a specific order, by which plugins receive deltas?

I am using the following plugin to detect outliers in sensor data (depth, STW, AWS): https://github.com/chris0348/signalk-detect-outliers This works fine for depth, STW and AWS. But TWS, that is provided by the derived-data plugin (based on among others AWS), still shows an outlier when the apparent wind speed AWS had an outlier. So apparently derived-data gets the deltas before they are handled via the detect-outlier plugin. Is there an option to assure, that the deltas that derived-data gets are handled before by the detect-outlier-plugin?...

SignalK server on Windows

Hi, I am running a signalK server on Windows 11. Now I am trying to use the data logger plugin to log my data. But I cannot get it to work. The signalK log say that file sk-delta-log.2024-07-22T11:38:34.052Z.log does not exists. Which is true. I don't think that : are allowed in filenames in Windows and reported a issue in github. I'll wait and see if Mairas is still active. Is there an alternative for the data logger? (Other than logging the NMEA0183 data comming from port 10110) ...

smoothing of apparent wind data

Hi everybody, is there an easy way or plugin available to smooth apparent wind data? Actually it’s mostly jumping around as the wind vane raw data. Thanks !...

is Seatalk 1 Gauge illumination level captured by the current Seatalk 1 plugin?

with the Seatalk 1 based ST60+/ST50 gauges, the illumination level is transmitted to the other devices when 1 device is changed. Is this code recorded in the current plugin? I would like to use it to trigger a change in light level or background color for other devices

How to get data from a JK BMS

Does anyone have experience with getting data from a (Jikong) JK BMS into SignalK? Either by bt, can or rs485. Maybe via a SensESP?

SK install on node 22.5.0?

Hello all, I am having issues installing SK on a couple of RPIs. First I tried installing on a Pi Zero 2W with Debian 12 Lite (Bookworm, no desktop) and sudo npm install -g signalk-server didn't complete after 14 hours (there were some warnings but nothing that looked like a real error). I assumed it was because of swap because the vmem for npm was very high and the Zero has only 512MB, so I tried on my pihole (RPI 4, Bookworm lite, 1GB) and that had the same issue but eventually completed (tail of error log below). I'm wondering if I should downgrade node or npm to a different version, or if anyone has other ideas. ...

NMEA 2000 configuration for Yamaha F150 outboards

Hi all, i have an rpi with latest signalk installed and was hoping to read engine data from N2K... I seem to only be getting GPS data... Does this mean that Yamaha uses proprietery PGNs that i would need to configure... At the same time i have an ActiSense W2K-1 installed and i am looking at the logs...The only thing of potential interest is the attached screenshot.. Any ideas?

wilhelmsk

I assume others are using the wilhelmsk app for building displays. If so have you found any manuals or youtub descriptions on how to build displays. Right now I am fumbling around but not getting far.

Multiple Signal K servers sharing all data

What is the best way to run multiple Signal K servers and have them share all data? In my setup, I have at least two servers, sometimes more. For these two specifically, they each source data that is not available to the other (e.g., Victron SK has battery information while rPi SK has all NMEA data). I want all data, including battery and NMEA, to be available to both. I can establish a WebSocket connection from rPi to Victron, but if I do it bidirectionally (meaning, a separate WebSocket connection from Victron to rPi), things start acting weird. I suspect this is caused by a loop of some sort. Attaching the WebSocket configuration for reference. Suggestions welcome....
