SignalK log files filled partition... (Victron Venus install)

I accidentally left NMEA0183 logging running, and it seems like there is no log rotation/auto-stop mechanism so my /data partition on the Victron Ekranos has filled up overnight. I cannot ssh in any more. I found a 'delete signalk logs' script and tried to enter that previously, but it didn't seem to liberate any space (according to 'df -h' anyhow). The Venus side seems to continue to run okay, but signalk is now kind of dead in the water....

Setting up Kip for different devices

Hello Is there somewhere I can find out how to set up different Kip dashboards for different devices. I understand I can set up different users and when they log in they get different layouts but I can't for the life of me work out how. It makes absolutely no sense to me how the storage works and I can't find any walkthrough or turorial/youtube video that explains it....

Code error

Venturing again into sensESP and am getting an error in VS Code "Could not find the package with 'SignalK/SensESP 3.0.0' requirements for your system 'linux_x86_64'" It has been select in the Platform IO project configuration. Computer is a MacBook pro running Ubuntu 24.04 Kernal version 6.8.0-51-generic(64-bit) I'm new to Linux but am learning to love it...

Sending test data to NMEA0183

How can I send data to the NMEA0183 output? My plan is to use SignalK to test my MOB sniffer (which has an NMEA0183 input). I'm using the MacArthur HAT - receiving of Messages works (from AIS). Unfortunately, I have no idea of how the JSON string!? should look like and if I can send it via the "DataFiddler". Any documentation / links will be appreciated....

Trying to us GPIO in Node Red on Pi 5 has trashed my signalk

Hello So I got node red working and wanted to use GPIO in node red on a Pi 5. After following this post: https://forums.raspberrypi.com/viewtopic.php?t=364182 And following the instructions to use GPIOD:...

nmea0183 over TCP-victron ekranos nothing seen

have been trying to use the signalK install on a Victron Ekrano, integrating with an nmea0183 network stream. I used my computer to verify that the TCP host:port combination is correct. However, I don't seem to be ingesting any data, and it is unclear to me what I should be doing in the 'server log' page to produce some debug information, as I assume there are some exceptions being thrown about something stupid I've done, but I cannot see them. What is the best way to debug a 'data connection'? I've attached a screenshot of my configuration for the connection....

Node red not loading

Hello. I was going to try to start learning how to use node red. When I click on the node red link in Webapps it just sits at "If your browser doesn't automatically go there within a few seconds, you may want to go to Node Red manually." How might I go about finding what the problem is?...

Help with Converting Energy Meter Data to NMEA 2000 PGNs

Hello, I have an Energy Meter ET112 connected via USB to a Cerbo GX, allowing me to monitor shore power usage on the GX Touch and Axiom+ through the Victron app. However, I’d also like to convert this data into NMEA 2000 PGNs so I can integrate it with other screens and applications. ...

Signal K not getting my Seatalk1 stream via GPIO on PI5

Hello everybody. My old PI3 with the Signal K version included in Openplotter V3 had no problem reading my boat Seatalk 1 data stream. After upgrading to a PI5 with the latest version of Signal K and using the same wiring and same GPIO port I get this error:...

Alarms from zones & hysteresis

I stumbled upon this issue when one of the temperature measurements is bouncing between configured zones and sending excessive amounts of push notifications. See the attached photo (copied from web) which quite clearly describes the case. Usually, such issue has been solved by setting a hysteresis range, for example in case of a temperature measurement it could be from 0°C to 1°C. When T goes down to 0°C, alert is summoned, but in order to clear the alert, T must rise to 1°C or above. I'm sure everyone is aware of this solution. The question is, how have you solved this, is there perhaps another plugin for triggering notifications or have you sorted it out with Node-RED? Or am I using zones wrong?...

Slow output from signalk-to-nmea0183

I need some help with the signalk-to-nmea0183 plugin. Data is coming out only every 60 seconds. The data originates from sksim and I can see that the data is being output from sksim about every 2 seconds. I can see that in the "Signal K Output" window of sksim, and also I see data changing in KIP at approximately 2 second intervals. However, when I connect TZ iBoat to the TCP port, I only see data every 60 seconds. I assume this is the rate it is coming out of signalk-to-nmea0183. Questions: 1. Is there any place in signalk-to-nmea0183 to set the output rate? 2. Is there another way to see the output rate of the NMEA data on TCP? 3. Are there other ways to debug or understand this problem?...

Signal K Error Processing RMB message

Hi the moderator on the Signal K to "Raymarine Seatalk NG" thread on OpenMarine Forum suggested I contact you. I find that when Signal K receives an RMB message from OpenCPN via a UDP connection it throws an error, which I don't fully understand. It seems to be related to a Null value for latitude even though there is no such value in the RMB message. This error is preventing the Signalk-to-nmea2000 pluging providing navigation data required by autopilots....

SignalK and microPython

What would be the best way to import/export signalK data on a dev board running microPython? I found this library https://github.com/ph1l/python-signalk-client but it has not been updated in 2 years.

Transmitting from Navionics/Boating App back to NMEA devices

I've got my signal K set up and having a blast with the data being sent over the network. However, I just want to make sure that there is no way that data could be transmitted back from my ipad onto the on board navigation equipment. Is there a feature/service which should be disabled to make sure that it's only broadcasting one-way?...

is the iKommunicate the only commertially avail SK server with built in NMEA hardware interfaces?

Likely many of us who want to interface NMEA to SK either go the Pi Hat with NMEA interfaces or perhaps a Pi plus a secondary NMEA <-> TCP box. Im curiuous if there are all-in-one boxes other than the iKcommunicate.

List of available hardware devices, open source and proprietary hardware.

I'm looking for device manufacturers of SK enabled devices. That might include: Gateways, Sensors, displays. Devices that interface with a SK instance. Does one exist?...

Hello

I am in my first days of playing around in SignalK, so please bare over with my stupid questions. Also Discord is at bit confusing 😉 I have quite a lot experiense with home assiastant and node-red, but I am NOT a programmer. I can do simple coding with help from ChatGPT. I want to be able to control all switches and dimmers on my boat from #wilhelmsk also I am working on switching and light control using node-red but I have af few problems as follows:...
