  Openplotter 8 does not remember settings?
Posted by: Ewald Harmsen - 03-31-2017, 11:36 AM - Forum: Bug Reports - No Replies

Hi All,

just installed Openplotter 8.0 (not NOOBS).
I can connect to wifi, but when I try to set the hostname, it asks me to reboot, and the hostname is not changed.

The same holds gor OpenCPN, when I change the display language, I have to reboot OpenCPN, but the language is not changed.
any solutions?

  Node Red remote
Posted by: AquaholicM31 - 03-31-2017, 08:58 AM - Forum: How do I...? - Replies (2)

Afternoon All,
First of all i must give my thanks to the Openplotter team, it is a fantastic system! Keep up the good work guys!!!

I have been playing with Node Red and got all my Signal K data into it and working well which is great. I can view all of this data on my tablet when connected to the pi wifi ap using
What i would like to know is it possible (with my pi connected to the internet) to stream this node red info so that i can see it on my phone from my house? Any tips or guidance greatly appreciated.


  I2C GPS?
Posted by: abarrow - 03-30-2017, 11:40 AM - Forum: General discussion - Replies (2)

I've read where others are placing a few I2C devices, like IMUs in a small box that they can remote to another location on their boat that is more appropriate for things like compasses and such. I just came across this I2C GPS module:

Has anyone done this? it would be nice to free up a USB port on the PI, and be able to put a GPS module in another location with other sensors.

  How do I get water temp into Node-red?
Posted by: dreuf - 03-28-2017, 04:13 PM - Forum: How do I...? - Replies (4)

When I go on Diagnostic on Signal K, I have MTW (environment.watertemp), but in node-red when I debug the websocket I can't find it.. Any easy way to get it there? Smile

  OP0.9 Update instructions please
Posted by: affinite - 03-27-2017, 06:11 AM - Forum: How do I...? - Replies (10)

would it possible to post some simple instructions to enable us to update our OP 0.9. 
I'm am a Raspbian/Linux novice and dont know my GIT pushes from my GIT pulls but I would like to keep up to date with the project rather than wait for a major release. 
With Openplotter being discussed on both Openmarine and Cruisers forums its difficult to keep track so perhaps a sticky thread (on here) with basic updating notes ?

Also, an update on 0.9 progress would be appreciated. 
Do you think 0.9 will be stable and usable this sailing season ?

Finally another vote of thanks for all your efforts (and for those of the wider OP developer team)

I'd like to use the Daisy AIS hat on a raspberry pi. Can that be configured to work in OpenPlotter? The idea is to have the data accessible from an iPad running iSailor.

  Connect Victron Battery monitor to Openplotter SignalK?
Posted by: kste - 03-22-2017, 06:00 AM - Forum: How do I...? - Replies (12)

I ask for help on how data can be read in the Victron battery monitor and send them to SignaK Openplotter of using this software?

  OpenCPN 4.6 on OpenPlotter
Posted by: abarrow - 03-20-2017, 07:32 PM - Forum: General discussion - Replies (6)

Hi all,
I just finished compiling OpenCPN 4.6 and installing it over the existing 4.4 version on OpenPlotter 8.

It seems to work fine - even perhaps a little snappier than 4.4. After I got the base directory correct ("/usr" instead of the default "/usr/local") it seemed to slot in quite nicely over the top of 4.4, and it uses the existing plugins and settings from 4.4.

So far, no bugs that I can see, but of course testing is in the early stages. 

Is anyone else using 4.6 on their PI, and if so, have you had any problems?

My compiled version is a fairly large DEB (about 90M), as I included the full version of the GSHHS model, but I would be happy to make it available to anyone who wishes to try it. Keep in mind I'm not smart enough to include the menu additions in the DEB, so if you install it without the previous installation of 4.4, you won't have a desktop icon or a menu entry, you'll have to create those yourself.

PM me if you want a Dropbox link to the DEB.


Photo NEW OP /OCPN Hardware
Posted by: henker - 03-19-2017, 09:43 PM - Forum: General discussion - Replies (19)

Hello OP / OCPN users
After reading this forum and noticing an increase in the Node-red usage, I have been working on some Hardware that might be interesting to some of you guys. This post is to see what the interest is among the OP / OCPN users is and I would like to receive some feedback just to see if it is worth continuing the development of this hardware. I have been in contact with Sailoog and he was very happy with the initial approach and was okay me sharing this with you all on the forum. These are items that I developed and tested so far:  (picture on the bottom of the threat)

-          Dedicated I/O board for Analog and Digital signals. These boards are stackable and can be directly connected to the Raspberry pi GPIO. We will be able to stack; 2 Analog boards or 1 analog and 3 digital or 6 digital boards. The Analog boards are based on the MCP3008 and have 8 inputs. The Digital board has 8 inputs and 6 relay outputs. All board have a 5V DC power supply to supply the RPI. Input Voltage is 9 to 36VDc, fused and reverse polarity protected.
-          Serial input board. This board can also be stacked on top of the RPI but doesn’t use the GPIO. Instead it will use the Pi’s USB connectors. This board has 4 NMEA RX and TX I/O’s with the FTDI USB to serial chip. We have added on each port an RS422 isolator. Again, this board is 9 to 36VDC DC and 5VDc RPI supply.
All these boards have connectors that make it easy to add / remove sensors.
-          Rudder feedback. I have developed a Rudder feedback, 9 to 36V in and RS422 NMEA our ($xxRSA). The system is based on a Hall sensor so no wearing parts!
Under development:
-          Windsensor. Also, 9 – 36 VIN, RS422 NMEA out. We have already put it together, it just needs some more testing. Again system is based on a Hall sensor.
-          Marine Monitors: 12, 15 and 19” touchscreen monitor. The 19” is finished and is being tested. The 12 and 15” will be ready in the next few months. We will try to make a Waterproof model as well.
-          Keyboard. I was thinking to develop a dedicated OCPN keyboard however, is there any interest in such a thing? Please advise if you would be interested and if so, what keys would you like to have on this keyboard.
-          Signal Conditioning board; This board will be able to handle signals from the vessels switchboard. All signals will be optically isolated: DC, AC, current and frequency.

The timeframe on this project depends on my regular job, however I would like to have the boards ready in the next month or so. Please note that ALL these items are build IN-house. These are NOT bought in China and re-sold!
Some changes to the first boards need to be made as I found some mistakes but these should all be ready in the next few months.
We tested the Serial and Analog board and these are working like a charm!

Offcourse you are wondering… WHAT DOES IT COST??? To stay in line with the OP / OCPN project, these parts will be priced very reasonable… Being a (sail) boat owner myself we have enough costs and any penny we can save is a bonus. The Analog / digital boards will be around E80 / US$85 / C$115. The serial board will be slight more at around US$ 125.
I haven’t determined the cost of the RAI and wind sensor but as there is quite a bit of work to put these together, there will be price between US$150 and $300. Also, currently, the housing is made from plastic which I prefer to change to Stainless…

Needless to say, the monitors will be more expensive BUT will be priced much cheaper as any other Marine Monitor currently available. Again we make these in house!.

Please let me know what you all think of this. Any feedback, bot positive but even more important, negative is welcome.

  Opencpn charts

This is welcome news for many, I suspect..

Up-to-date vector charts for OpenCPN - oeSENC

A major stumbling block for many using OpenCPN has been troubles getting charts other than the aging cm93, not no more!
Well done sailoog, I believe you played a part in this.
