WilhelmSK app shows what Signal K, good boat WiFi, and smart DIY coding can do

    PS Scott also has a Fusion stereo on his Catalina and wants to incorporate the Fusion-Link N2K remote interface into WilhelmSK.

    Kees, I would be eager to hear more about the new airmar STW sensor with leeway of course, but would you keep your ear open and learn if the technology providers and volunteers are keen to bring it to us? For example has Signal K laid any ground work?
    Would love to hear more on Racegeek (I enjoyed visiting their site today)
    Is Raymarine planning any more sailing features this coming season? Time to start line was originally in advertisements, but didn’t happen. is that coming soon?

    Very nice. As with all IP based communications, who is monitoring for accidentally built-in security risks. Standard “security packages” have readily been compromised. Does Signal-K have a security czar?

  4. Ben Ellison Ben Ellison says:

    Don, I believe that security is a concern of the Signal K team, though I don’t know what’s been implemented so far. However, readers should understand that most everything I discussed and illustrated above was or could have been done strictly within my boat’s local area network. I suppose someone could figure out the password for my WiFi router but they’d have be close to even see it.
    Dan, I too hope that Kees can visit the Airmar booth, but I do have some details about the DST900+ Multilog and they sound amazing. Patience please 😉

    The SignalK team and I are definitely thinking about security. It wasn’t too big of an issue before since everything was just read-only. Now with my addition of autopilot control, security definitely needs to be address and there are efforts in progress to add security to the signalk-node-server.
    Like Ben said, WiFi security is a good way to handle this right now and is probably as good as anything we would add to the servers. But as more people like me have their SignalK servers accessible over the internet, this will become an issue.
    I currently shut down internet access to the boat when I’m out and about. I wouldn’t want someone changing the satellite radio station to the Justin Bieber channel 😉

    That looks like a very useful piece of kit.
    What setup are you using to get data from the Volvo Penta? I have an old one and would be great to get data into a tablet display

  7. Ben Ellison Ben Ellison says:

    Hi Andrew,
    For several years I’ve been using the Actisense EMU-1 to convert the inputs to my Volvo Penta gauges into NMEA 2000:
    I look forward to trying a recent EMU firmware update that apparently adds some nice improvements. I also tested and liked a VeeThree Engine Gateway Monitor:
    But if your Volvo Penta is newer than my 1999 model, it probably uses the J1939 data protocol, and for that there are other options from Maretron, Yacht Devices, Garmin and more.

    Got the wilhelm SK app and I am trying to get some support but Scott’s website has been down in the last few dates.
    Any alternatives on how to setup the server software on a Raspberry Pi or even a wilhelm SK manual ?

    Hi Adrian,
    If you’re looking to install the Signal K server on a Raspberry Pi, take a look at this guide. If you have any questions or run in to issues with that, please post on the Signal K Mailing List and someone will help you get it all working.

  10. Scott Bender says:

    Hi Adrian,
    Sadly. I have not had time to build a website yet. You can email me @ [email protected] for support.

  11. Adrian says:

    Thanks Tim and Scitt,
    Will reach out to you via email Scott.

  12. Donald Joyce says:

    What I’m most concerned with in general is the inadvertent introduction of malware or vulnerability into the software by a contributor or vendor. Therefore a security czar to encourage best security practices and ferret out problems before distribution. In the past this was my biggest headache when coordinating “volunteer” development projects. Lots of innocently introduced issues by very thoughtful, well intentioned competent people.

  13. Scott Bender says:

    I finally managed to get a website up. More information on WilhelmSK can be found at http://www.wilhelmsk.com

    RaceGeek is taking orders for their D10 display, which is planned to ship in late April:

    I love willhelmSK — I just installed it and it worked perfectly with my iKommunicate. No configuration necessary.
    I made some install and configure videos for the iKommunicate here:
    The willhelmSK app is featured in video part 3.

  16. Dan Corcoran (b393capt) says:

    I enjoyed reading this entry, which involves creating a powerful sensor for your boat for the cost of a $35 IMU ( inertial measurement unit on a chip) plus an $18 development board. Add a few wires and you have roll, pitch, yaw, heading, rate of turn, temperature and atmospheric pressure output in Signal K.

  17. Hi Ben,
    we added the support of Raymarine autopilots to our wi-fi, usb and nmea 0183 gateways:
    Now, any app (PC or mobile) can control the autopilot using APB/RMB sentences of NMEA 0183.
    Tested with SPX30 and EV-1 using OpenCPN.

  18. Great article, thanks a lot. Maybe I missed it but how did you get the radar image to WilhelmSK and can you set it up and change the settings without a plotter? Thanks for your great work here
