How do you hide/unhide regions in Freeboard?

Given the new fantastic map caching feature use of regions is increasing as they can be used to define a seeding job. I expected Regions to show up in the layers meny like e.g. routes, but in my case they do not. Feels like I'm missing something... ...

Start over with new install

I’m planning to do a reinstall of my signalk server this winter. Main reason is to get up to date with nodejs to avoid any issues during the summer. Any recommendations on how to do a fresh install when I have a pi5 with a pecan-m hat?...

Autoscrolling in web-gui

When I change the configuration for a plugin and hit "Submit", the list of plugins autoscrolls to the top of the list and also closes the dialog of the plugin, for which I just changed something. Since I have a lot of plugins and some plugin config-dialogs are quite lengthy (charts plugin and others), this autoscrolling and closing is a bit "annoying". I always have to scroll until I have found my plugin again and the open it again. I remember, that this automatic behavior was introduced a few years ago. Before, the plugin list did not have this automatic scrolling. Is there any way to prevent autoscrolling and autoclosing?...

Which custom data path for plugin to use?

I am thinking of extending the tracking plugin https://github.com/noforeignland/nfl-signalk to not only tell the dashboard when the last save point was created or when the last track was sent to the API etc. I would love to crate a data path that I can use f.e. in KIP etc. I am a bit looking at the starlink plugin that gives me: network.provider.starlink.*...

Influxdb v2 and grafana geomaps?

I'm using signalk-to-influxdb2 to record navigation.position. I thought I would be able to then have grafana query influxdb and draw on a map. But I can't seem to get anything to work using the fluxQL query builder. It works find for "scalar data" such as speed, course, etc, to draw graphs, but can't grafana to understand navigation.position and get the lat/lon data. Any suggestions?

Securing against non logged in users...

As the titles suggests, I am trying to make it so that a user needs to be logged in to see anything, rather than just logged in to be an admin. I must be missing something really really simple, as any user I have can be read only or admin, but if you are not logged in, it can still read my webapps, etc. I have searched around the docs, which touch upon UNIX like permissions, and various web posts that talk about the security.json, and settings.json, but I am not understanding how I can simply not let users access any SignalK data without being logged in....

Where to increase emitter.setMaxListeners() ?

I am accessing SK from multiple devices, browsers and browser tabs. Where can I increase this setting?

Use emitter.setMaxListeners() to increase limit (Use node --trace-warnings ... to show where the warning was created)...

Resources v1 vs v2 and their visualization in Freeboard

Hi, I'm running a signalk-installation, that I have continuously updated over the last two years. I now run v2.17.2. I have a number of waypoints and notes stored at ./signalk/resources/waypoints and ./signalk/resources/notes While I have the latest Freeboard installed, I also run an older customised Freeboard based on Freeboard v1.19.1....

Notification messages crashing SignalK

Hi everyone, I can't be the only one who has notification messages flooding my monitor and crashing SignalK server. When my Raymarine Autohelm looses track it sends a message on the NMEA 2K network. This places messages on the screen. When it happens I can't connect via VNC or SSH. What can I do to block the messages....

Fire exercise warnings

Do not know if this is commonly used on all countries, but at least in Sweden when there is a live fire exercise going on they put virtual AIS markers "out there". Would it make sense to create som kind of alarm if your vessel is approaching one of these?...

AIS to SK

I installed a USB SDR radio and AIS-catcher, and configured AIS-catcher to send to UDP 10110. SK is receiving/logging 0183 VDM messages but not parsing. Can anyone recommend a plugin that will parse the data? There are lots of AIS plugins on the app store but none seems to be a simple parser--I don't need forwarding etc.

Raymarine Axiom Oil Pressure Duplicates

I have a Raymarine Axiom which receives data from an AlbaCombi. I am using SignalK with NodeRed to estimate the fuel consumption from the RPM of the engines (on the basis that this is a better way of doing it than me simply noting in the log the RPM and an estimate of fuel usage) using the published fuel consumption curve. Now the strange behaviour is that when I use the SignalK - NMEA2000 plugin and map the calculated value back into an Engine PGN the oil pressure on the axiom flips between (at...

Chart caching for Freeboard SK

I am wondering how freeboard sk saves the charts from online sources, like openseamap and openstreetmap. Looking into this since I will have internet for only a couple hours a day for a trip and want to know if suddenly these charts will disappear.
