  Signal K MQTT Node Red
Posted by: wkmhv - 06-08-2018, 11:57 AM - Forum: How do I...? - Replies (15)


there is no manual for MQTT on openplotter 1.0.0..
Have tried the following:

In MQTT username and password entered.
[Image: openplotter1.png]
Is the Type K key input correct, or is the signal K delta input or General?

[Image: openplotter2.png]

Try General.

[Image: openplotter3.png]

navigation.gnss.satellites are currently 8.

[Image: openplotter4.png]
 Then I choose in openplotter "Action" and add to create a trigger.
As Sinal K key I choose navigation.gnss.satellites. Can you test well at home. Move the GPS a bit away from the window and the number of satellites changes.
As the value I choose <10.

[Image: openplotter5.png]
Then click add under action.
In the selection, take "Publish on topic: satellites".
Then click on "Appley changes".

What happens now? Nothing.
Where does the edition take place?

Try Node-Red.

Drag Input Mqtt element onto the surface.
Enter as Topic satellites.
[Image: openplotter6.png]
Drag the output debug element onto the surface and connect the nodes.
Click on "Deploy". If then under satellites connected, the connection should be OK.
If I open the debug window, nothing happens.
What did I not understand?

  [CLOSED] Translation failure
Posted by: Otoio - 06-07-2018, 06:48 PM - Forum: Bug Reports - Replies (2)

Hi guys,

There is some wrong in this spanish translation of OpenPlotter.
As it's seen, there is a sentence in basque in a Spanish language translation.

Not very important but it could be very painful for some people, you know  Cool

  GPS USB-Mouse is no longer recognized by OpenCPN
Posted by: waldmattis - 06-07-2018, 03:08 PM - Forum: How do I...? - Replies (7)

Good evening
regrettably my GPS USB-receiver is not recognized by actual Openplotters OpenCPN.

In the previous version all worked fine.

The system recognizes the receiver / see listing from   lsusb
pi@openplotter:~ $ lsusb
Bus 001 Device 006: ID 1546:01a5 U-Blox AG NL-402U
Bus 001 Device 005: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
Bus 001 Device 004: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
pi@openplotter:~ $

The device is    Navilock NL-402U

In Openplotters previous version it could be found in the NMEA settings.
After activating per mouseclick and running diagnostics, the GPS data come in
and were used by OpenCPN.

In the new version there is no entry for this GPS device.

Who knows help_

  Battery Monitoring
Posted by: AliceJ21 - 06-07-2018, 02:42 PM - Forum: How do I...? - Replies (2)

I have dabbled with the INA3221 in v.0.17.1 and tried to do the same in V1, however I fried both the Pi and INA module, having replaced the Pi and a replacement INA3221 on its way, I have started wondering what is the easiest means to measure the 3 batteries separately? INA3221 wasn't displaying a voltage in V1 when it was non-fried...

Also, if I wanted to measure current, I know I would have to use a shunt, but then how would I wire it up?

Can I use a voltage divider with an ADS1115 to measure each battery?

Sorry for all the questions! Spent the last week experimenting but come to a shuddering halt...


  VDR playback in v1.0.0
Posted by: baltika_no_9 - 06-07-2018, 02:02 PM - Forum: General discussion - Replies (2)

The normal recorded file that I use to test VDR playback doesn't seem to work in OP v1.0.0. It has worked in all previous versions and it works on my Windows OpenCPN 4.8.4 system.

The file I use is found here: https://opencpn.org/wiki/dokuwiki/doku.p...s:logs:vdr

Look under section "Want to play ?" and there is a link to download file rausch_shortened.txt.

Does anyone have this file working with v1.0.0?


  *newbie* /dev/root full after 24hrs
Posted by: Yannick - 06-06-2018, 01:27 PM - Forum: Bug Reports - Replies (19)

I'm new to openplotter

After a fresh install in a raspberry pi 3, 8Gb SD, after about 24hrs of running the pi the /dev/root folder is full and if i reboot the pi won't start anymore.
Made a fresh install 3 times, same result.

I'm new to linux, and don't really know where to solve this problem.

  Who know Charts for european waters, that work with Openplotter?
Posted by: waldmattis - 06-06-2018, 05:29 AM - Forum: How do I...? - Replies (5)

Good morning.
Who knows charts for european waters that work with Openplotter?
Of special interest are the coasts of the Baltic Sea (Ostsee).


  Who succeeded in using sea Charts from Nv-Verlag?
Posted by: waldmattis - 06-06-2018, 03:56 AM - Forum: How do I...? - Replies (1)

Good morning.
Yesterday I installed newest version of Openplotter and Switches Fugawi-Plugin on to use sea charts from NV-Verlag with their copy protection dongle.

The sea Charts are not recognized.

Using OpenCPN under Windows 7 with the Nv-Plugin makes excellent use of the dongled NV-Charts.

Is there a solution for Openplotter?


  OpenPlotter and Raspy ¿3, 3+B?
Posted by: Otoio - 06-05-2018, 12:48 PM - Forum: Documentation - Replies (3)

In the official documentation it's said that OpenPlotter is compatible with Raspberry Pi 3.

Would be better to say that it's compatible with Raspberry Pi 3B and 3B+?
We could understand that both are under "Raspberry Pi 3" but if we specified both it would be clearer.  

By the way, what about 2B?


  Translating images
Posted by: Otoio - 06-05-2018, 12:21 PM - Forum: Documentation - Replies (2)

Hi, guys.

How could I translate an image whose text is in English?

For example:
[Image: assets%2F-L9g5MoJ9GSCaNGq_yjb%2F-LCPrzzc...3d60d8b8e5]


I want to translate it to Spanish.
I'm not sure if I should insert a new image in the page in gitbook or if I should edit an image wich already exists...

(And I'm not sure if this way is an appropriate way to speak about this or I should use the contact form or email in http://www.sailoog.com/, sorry)
