Where can I ask questions about SensESP?

Where can I ask questions about SensESP... The only one I've had limited success with is the initial template. Nothing seems to work out of the box from the examples.

Trigger an n2k switch via a url?

Is there any way to trigger a switch via a url? I have terminal only access to the n2k server as I shut my router down by accident. Is there a way I can send PGN 126208? By hitting a SignalK url or the likes?...

Furuno Class A AIS through Actisense Gateway

A Saillogger user is using a Raspberry Pi with an Actisense Gateway. Everything on N2k shows up with the exception of AIS targets coming from Furuno Class A receiver. We know the receiver works as they can see AIS targets on their Chartplotter without any issues. I am attaching their N2k configuration. Any suggestions?...

Guidace on InfluxDB Config settings?

I realized I was sending nmea data in every second. I'm thinking maybe 10s interval should be fine. I'm also now filtering all the navigation and vessel data as that's not as useful for trends. Any other pointers on influx settings?...

SK on Rpi5 freezes

Just got a new setup on a RPi5 going and I though everything is fine... Running SKSim to feed data into it. Was noticing KIP would seem to freeze. Checked the SKSim Output and I see the data going out at a steady 1Hz. Went to the SK server logs and started seeing gaps in the time stamps Which are corresponding with when I was seeing the KIP Freezes. Where should I go to see what the issue could be? Especially since there's no errors in the log. My N2K Buss will be feeding data at much more than 1Hz. Got a race on Saturday and was hoping to have the new setup rock solid. - Thanks in advance...

KIP buttons to trigger mqtt message

I link signalk to homeassistant through Matt, using the gateway plugin; works great for paths signalk is aware of. Kip has a buttons option, how do I use that button to send an mqtt message? Or any other path for that matter, I'm not sure how to make new paths that the button will recognize. Anyone have experience in similar?...

Are there plans to make a influxdb3 plugin variant? The FLUX api in influxdb2 is being replaced.

working through setting up influxdb2 and realized how different FLUX is from the what I'm used to.. then went reading the docs and it looks like they are changing again to normal sql syntax for influxdb 3. curious if we have any thoughts and plans on this? @Teppo Kurki ?

Can't connect Sensesp to SignalK

I have both setup on the network with the Sensesp at 192.168.4.1 and SignalK at 192.168.4.211 but I don't see an access request in SignalK. SSL is off, mdns is enabled. The two devices are sitting right next to each other. SignalK is on a Pi5 running OpenPlotter. I even tried making sure that both were using 2.4Ghz, but that didn't make any differnence.

NOAA ENC Charts

I've used Open CPN to download the NOAA ENC charts for California. Downloaded to the /.signalk/charts. It created a series of folders inside i.e. /home/rhumbrunner/.signalk/charts/ENC/US_CA/US1WC01M... Inside those are a series of .txt files. How do I get the Signal K Charts plugin to process these files and make then available to Freeboard SK? I have tried adding the full path inside the plugin like above and still nothing is showing up, only the MBTiles I had previously downloaded are there.

SignalK Compress N2K Logfiles

My SignalK is quite nicely creating log files every hour in the .signalk directory. Is there a way that I can get SignalK to gzip these files when it is done? I was thinking about a cron job to gzip anything ending in *.log that has a minage of 120mins if not - is that the simplest approach? Thanks...

SK not Updating

I tried to update to 2.13.4 and could not get SK to update. I tried to update from 2.13.3 to 2.13.5 an still no luck. I have made sure the RPi is updated and follwed the update instructions on the SK Updating Your Installations page. Node version is 18.20.7. Any ideas?

Contact for Raymarine regarding SeaTalk¹ licensing terms

Hi all! I have recently written a Linux Kernel driver for SeaTalk¹ so that I can send and receive on my SeaTalk¹ bus from SignalK. I want to attempt to get this into mainline Linux, but before I do that, I need to be sure that Raymarine won't stand in the way of me doing so. In order to do so, I want to talk to someone at Raymarine to confirm this.

Canbus on Windows

I'm dropping an AliExpress 12v fanless PC into the boat to run the bridge between the B&G H3000 and the Raymarine N2K pilot and whatever else I want to run. I want to run windows on it. Has anyone run Signalk hooked up to a USB canbus adaptor on Windows? The whole socketcan thing works beautifully with Linux but obviously is not available on Windows....
