Signalk on Pi Zero 2w install hangs.

Ah.. Here you all are. I wondered where everyone had got to. I was wandering around the github discussion thinking it was awfully quiet and everyone is here having a party! Anyway: Hello I have been trying to install Signal K on a pi zero 2, just for testing and as an experiment. I have got to the actual installation part (sudo npm install -g signalk-server) and it appears to have hung my Pi zero 2. I can ping the Pi but get no response from my SSH sessions. The CPU seems to max out at 100% and no mouse response if I connect a screen/mouse to the HDMI output. I have left it like that for several hours with no progress. I am running the installation in a screen. Any thoughts or options? The last output from the installation is:...

Navigation data to MFD

Hello! I am so close to having a fully connected system between my autopilot, MFD, and signalK server. I set the MFD to send and receive navigation destination, and I see that the data for that shows up in the data browser, but it's not showing up in Freeboard. I also don't think setting a destination in Freeboard sends anything to the mfd. I'm using a ShipModul MiniPlex (ethernet) to handle the communication to the NMEA 2000 MFD. It shows up as NMEA 0183 over TCP for SignalK. The MFD is successfully recieving AIS targets from SignalK....

KIP Tank Contents

I’m trying to display fuel and water tank quantities in litres rather than percentage full. Given that the linear gauge has the option to show maximum and minimum values I would have thought it possible to display quantities knowing the percentage. Eg. If the tank is 0 to 400 litres and the signal is 0.5 or 50% then can the display be made to show 200 litres? If it requires writing code or more complicated stuff then it’s probably beyond me at this stage. I’m hoping it can be done within KIP.

Data refresh issue when connected to AP/HotSpot

Hi everyone, My SignalK test setup work fine when my Raspberry Pi is connected to my home router (acting as client). Accessing web page and NMEA0183 data refresh work fine. I configured a HotSpot on my Raspberry to access the Signal K Data browser and KIP plugin web page with the HotSpot IP address. ...

WilmhelmSK on Apple Watch

I have WilhelmSK displaying data on my iPhone. From what I can see, you can also display data on an iPhone. However, there's no Apple Watch app for that, so I'm baffled as how to do this. Any help would be appreciated.

How do I delete SignalK logs after downloading them

I am using SignalK to log everything on the CanBus, this seems to work quite well, but when I download them I can't find a way to delete the ones I have already downloaded, which requires downloading them all again. How can I purge downloaded logs please?...

Unable to restart server

Having attempted to configure a plugin (NFL) I can't restart the server. I don't getthe "hamburger" top right hand side nor the login or restart prompts. Rebooting the Cerbo GX allows me to bring the Venus GUI up again on windows and allows me to enter the login credentials for admin again. When I do so I get "Security has been enabled, please restart the server" message in red but have no means to do so. I have tried a start also via the CLI interface as well to start the server. The server l...

Can't view the UI at 192.168.4.1 after installing SensESP

I'm looking forward to getting started with sensors but I've been stuck for a few days now. I'm basically not able to get SensESP to connect with Signal K. My setup is: Pi5 OpenPlotter 4...

Is there a way to hook up SignalK to networked Garmin plotters?

I'm buying a 722SX to replace my 720S, and the 722SX has LAN ports. It supposedly is able to share sonar data from the transducer, and I would of course love to have that on my forward steering position. I suspect it's totally proprietary, but there's always a small glimmer of hope...or maybe there are other things to read out of the plotter with a network connection to SignalK?

plugin Venus on Sk on Os venus Large

Hi everyone, I'm using SK installed on Venus Os Large on Cerbo Gx, I read that the "Venus Os" plugin does not have to be installed because it is already present in Sk installed on Venus Os Large. In this way, however, for example, I do not see the tanks that arrive at the Cerbo or the RUUVI sensors connected in bluetooth and also other devices connected to the Cerbo. Did I perhaps misinterpret the instructions on signalk-venus-plugin? Thanks

Remote debugging in V3.0?

I've just converted my SensESP app to V3.0, which does not have easy serial debugging. Under V2 this was not a problem: pop in -D REMOTE_DEBUG under the build_flags and I could easily telnet into the ESP. According to the upgrade documentation this should work under V3 as well, however when doing so the connection gets refused on port 23.

12v breaker panel keys

Old B&G sensors to SignalK

Dear all, I recently bought a 40ft ketch (1988) with quite some old sail boat electronics. Most of it are NMEA0183 devices, a SeaTalk Autopilot and some funny looking analog B&G sensors. I would like to start a SignalK project and have already a few ideas for my digital boat concept but right now I'm struggling with my depth sounder and wind vane. B&G Hornet 4 Anemometer and Hecta depth sounder. I have no idea what kind of standard this is and if it's worth to implement them I to my signalK server. Both of them are working and connected to analog displays in the cockpit ...

language packs

Hello friends, maybe someone came across language packs, where to find them if they exist. And also how to add the units of measurement of your country, has anyone done this?

DC Load - Data input nit available

I created a new calc for the Derived Data plugin to calculate the total DC load. One of the data points is the DC output of the shore power charger. But, when I am away from the dock and the shore power charger is off, the calc does not work. It works if I turn off the charger and it still has AC power, because the output is 0. But, when it is off with no AC power, it does not exist. How do I check for this and have the calc decide what calculations to use? Thanks....
