  signalk-vesselsetup-plugin cannot be installed
Posted by: Luckbert - 10-10-2017, 05:45 AM - Forum: Bug Reports - Replies (7)

Hello, everyone.now that one problem has been solved, a new one appears. 

I want to install the "signalk-vesselsetup-plugin". 
The following error message:

npm, ,ERR!, Linux 4.9.35-v7+
npm ERR! argv "/usr/bin/node" "/usr/bin/npm" "install" "signalk-vesselsetup-plugin"
npm ERR! node v6.11.4
npm ERR! npm  v3.10.10
,npm ,ERR! Error extracting /home/pi/.npm/signalk-vesselsetup-plugin/0.4.3/package.tgz archive: ENOENT: no such file or directory, open '/home/pi/.npm/signalk-vesselsetup-plugin/0.4.3/package.tgz'
npm ERR! 
npm ,ERR! If you need help, you may report this error at:
npm ERR!,     
,npm ERR! Please include the following file with any support request:
,npm ERR!     /home/pi/.config/signalk-server-node/npm-debug.log

If I understand the message correctly, the file is missing. But I didn't find anything to download them. Apart from that, other plugins also download themselves automatically. 

I tried to download the plugin from the SK-AppStore. See Error.

I tried to enter "npm i signalk-vesselsetup-plugin" in the terminal. See Error.

What can I do?

Exclamation Integrate qtVlm on OpenPlotter
Posted by: Sailoog - 10-09-2017, 01:17 PM - Forum: General discussion - Replies (30)

qtVlm developers have contacted us to integrate this great software on OpenPlotter.

qtVlm is a navigation and weather routing software: http://www.meltemus.com

The problem is that qtVlm is not open-source. When we started OpenPlotter project we decided to try to collect only hardware and software which match at least 2 of these premises: low consumption, low cost and open-source. Now qtVlm just matches one of them and we would have to say no but we prefer to ask you first.

We have started this poll to know your opinion, we will do what the community decides.

P.S. We are Catalan, we love voting but be careful a Spanish policeman could hit you ... Wink

  [SOLVED] No signal K keys to choose, Questions during update
Posted by: ElbeTaxi - 10-09-2017, 07:10 AM - Forum: Bug Reports - Replies (12)

Hi! Some days ago, I installed a new OP from a recently downloaded 0.10-NOOBS-File, then upgraded to 0.15.1 beta via the update function within Openplotter. Ist a Raspy 3.

Everything seemed to work good.

Now I wanted to Setup my 1W Sensors. In the 1W Tab, I go to add. There I can choose one of my four sensors, can give it a Name, but the field "Signal K key" is empty, no Dropdown. Klicking the field does nothing.

As i remember, there should be different Keys to choose. Without the ability to choose or edit this field, ist not possible to save a sensor.

So what could be wrong?

One more - may be related -  question is:
Everytime i do a update/upgrade, there are misc error messages and warnings (to fast to read/keep). And, there are at some points interactive questions like "this file has been changed, wich version do you want to keep?"

What is the right choice in this case? Keep? Overwrite?

I think im not the only one who isnt experienced enough with the system, to make the right choice... Smile

THX in advance! Smile

More details about the problem, i think this could help to solve? Here is the output of the debug-terminal when restartig Signal K. Sorry for providing it as a Picture, as i dont know how to copy / paste it from the remote desktop of the Raspy...

It says its missing a file: keyswithmetadata.json.

  How do I send the state of GIPO sensors automatically after reboot?
Posted by: Alpenskipper - 10-07-2017, 06:13 PM - Forum: How do I...? - No Replies


The GPIO sensors have to be (re)started manually after a reboot to see the values in Signal K. If they change their state, the value is transmitted on Signal K.

Is there a way to start them automatically after a reboot?


Question Change VNC Server Resolution?
Posted by: Leigh - 10-06-2017, 05:12 AM - Forum: How do I...? - Replies (2)


I have my 15.01 version OP working via VNC to my Nexus 7 2012, but the VNC server resolution is not quite right.

Could someone tell me what I have to alter/add to config.txt to give 1280x800 resolution, please?


  A beginner can manage it! - RPi3 + Sensehat

My setup:

[Image: OpenPlotter%20Headless.jpg?raw=1]

  1. Raspberry Pi 3 in Shortcrust case
  2. Sensehat moved out of Shortcrust case with 2x20 pin ribbon cable (pulled GPIO connector block off of of bottom of Sensehat to allow correct connection)
  3. Downloaded 0.10.0 OP from the website & installed it
  4. Updated everything from the update tab in OP (Raspbian, OpenCPN, OP to 0.15.1)
  5. In OP ticked the Mag Heading, heel & pitch in the Compass tag
  6. In OP Added the listed sensors in the I2C tab
  7. In OP Tools > NMEA 0183 Generator > OpenCPN defaults
  8. In OpenCPN right click Dashboard > Preference: Add, Heel, Pitch
  9. Headless, VNC to Nexus 7 2012
  10. Signal K to 'phone
  11. I will scan my charts for Lisbon (or maybe make a copy stand for my SLR and then stitch photos) 
  12. I have bought John Thorn's MAPC2MAPC software to calibrate scans
  13. Just waiting for a GPS and a 12V -> 5V DC supply from Sailoog's site to complete

Very minor, but thought might help

True Heading (calculated from Mag HDG) will go to -2 deg before going to 357

Sad OpenPlotter development affected by events in Catalonia
Posted by: Sailoog - 10-05-2017, 01:17 PM - Forum: General discussion - Replies (9)

Hi OP users,

As you know we are set in Barcelona. We have been affected by violent actions of Spanish police against the referendum day of October 1. No one is seriously injured but we are still in shock. We have not much time to work on OP now but we hope we can catch up with development soon. We are close to the stable version and just few major updates are left, please keep with us.

  openplotter v0.10.0alpha : hostapd not starting
Posted by: sanrab - 10-05-2017, 03:03 AM - Forum: How do I...? - Replies (6)

Hi, I'm testing openplotter v.0.10.0alpha NOOBS.
Everything seems to work except wifi AP. I'm using a wifi dongle (ASUS USB-N13) that perfectly works in 0.8.0 but not in the alpha version. 
The status Info in openplotter WiFi AP says

missing AP! or driver is not nl80211
up network: wlan0
dnsmasq (dhcp server): running
hostapd (AP): stopped
networking: started

ip address wlan0

Any suggestion ?


I forgot:
RaspberryPi mod. 2
OpenPlotter 0.15.1 beta

  How to save my work in node-red?
Posted by: Alpenskipper - 10-04-2017, 09:38 AM - Forum: Node Red - Replies (3)


I started to experiment with node-red and - it's great!
After fiddeling around with freeboard for more than a year, it just took my a few hours to create a working dashboard, where I can monitor my boat when at home.

How can I preserve (and restore ) my work in case of system crashes or updates?

best regards
