  Solar panel monitor
Posted by: Bojayne@yahoo.com - 11-11-2018, 05:31 AM - Forum: Feature Requests - No Replies

I have a victron smart solar with VEdirect to USB cable.  I found a script that is supposed to be used on the Raspberry but I am completely new to this system and cannot figure out how to integrate it.  I would like to use it for remote monitoring of battery state. There are several alternatives listed in Victron Open source page.

  Actions will not "show message"
Posted by: Lazzz - 11-11-2018, 04:28 AM - Forum: How do I...? - No Replies

Running the latest OP on a Pi3 when an action is triggered it will not show a message. It will play a sound & publish to Twitter etc but the show message does not work.

This has been since the major upgrade.

Any ideas!!


  No actions triggering in openplotter 1.2.0 alpha??
Posted by: theshade - 11-08-2018, 10:21 AM - Forum: How do I...? - Replies (1)

Hello All,

I have playing for 24 hours now trying to send some signalK to the local MQTT broker.
I know the broker works fine and using:

mosquitto_pub -h 0.0.0.0 -p 1883 --username 'sgs' --pw 'erair' -t 'Time' -m "Hello"

works perfectly and I can remotely read the Topic from my computer so that is working fine.

But I have been trying for hours to have a trigger + action working and doing anything and it's simply not triggering or acting.
I have tried dates  with >= and <=. I have tried satellites count bigger and smaller than. I have been trying to publish stuff, send messages and e-mails and all the actions which I could possibly find in the list but nothing seems to trigger.

Is there something else I could check to make it work, what did I miss?

Thank you in advance,


  Also send I2C sensor data to Node-Red so ALL instruments show on the dashboard
Posted by: NaturalBornCamper - 11-07-2018, 10:31 AM - Forum: Node Red - Replies (3)

Hello all, long overwhelming message coming up.. Hopefully Node-Red is my way out

(If you feel like TL-DR, the important questions are in bold)

So in the past few weeks, I have read so many websites about concepts, communication protocols, documentation and I still don't understand 90% of what people are talking about on this forum, or what OP does "exactly".. I don't get it, I'm a software engineer and I feel stupid haha! Everybody seems to understand perfectly what spaghetti all these protocols and terms build togheter: MQTT, i2C, NMEA0183, NME2000, 1W, SPI, Signal K, Serial, GPIO, kplex. They all seem interconnected but I fail to see the big picture, where all the data passes by, even with the documentation workflow image, plus many of the pages about the things I don't understand like MQTT and SPI are empty in both old and new docs.

So anyways, I managed to make our analog oil pressure sensors work with an Arduino Uno board I had lying around and send it over I2C to OpenPlotter, until I realized that you can only add sensors that were pre-configured in OpenPlotter, not custom sensors. So I cloned the OP repo and searched in the code where that list was to configure my own I2C sensor in the files (add_i2c.py, openplotter.py, the .pypilot/RTIMULib files) until I realized that thers's no way the devs wanted it to be that complicated.

Then I read this thread about someone trying to send data via I2C from Arduino Uno to RPi with the same problem as mine:
http://forum.openmarine.net/showthread.p...hlight=i2c
And most people seem to say that Node-Red is the solution (I avoided it until now since I thought it was a programming language for kids like scracth hahaha). Is there a way however to send the I2C data to Node-Red somehow? If I can get the oil pressure on a dashboard there, AND other I2C (like the BMP180) sensors to all display there without having to use the Signal K instruments panel, it would be awesome! If there's an obvious solution to only use Node-red for everything, please point me in the right direction and I'll do my homework and read the docs, as long as I stop going in circles!

I've seen amazing Code-Red dashboard in the forums like these:
http://forum.openmarine.net/showthread.php?tid=1087
And this one (Unfortunately using MQTT that I don't undersand):
http://www.ybw.com/forums/showthread.php...d-node-red
and now I really want to use it, I got some great tutorial videos and links so I'll go read this tomorrow.

In the meantime, can someone also answer these questions please:
-Is it possible to send I2C data to Node-Red? I liked i2C because I can just connect the Arduino Uno to SCL and SDA, without needing a level shifter or resistance + no need for a USB hub (as I can't get one now far from a decent town). Not sure if I'm supposed to use something like this:
https://github.com/SignalK/node-red-embedded

-Am I supposed to send the i2C sensor data over NMEA using the generator somehow? It seems like it's only pre-generated sentences with specific sensors, nothing custom.

-Can OpenCPN display other data than NMEA? For example i2C, Serial or GPIO sensors, I guess by using plugins like "Dashboard"?

Thanks for reading all this and enduring my confusing post XD I feel like I can't see the easy way out in front of me, just like this picture XD


  serial output
Posted by: Newt2u - 11-07-2018, 08:55 AM - Forum: How do I...? - Replies (1)

Not sure if this is covered elsewhere, could not locate any information either here or in the V1.x.x documentation. I am running V1.2.0 on an RPi3. This problem was discussed in a more general thread but because of my inexperience, the discussion was a bit unfocussed. Here is the problem in more precise terms.

I would like to output RMC NMEA sentences to my autopilot via a usb/serial converter. RMC is input to kplex via the "system" UDP connection from iSailor/iPad on port 10110 (this is working). In particular, I want to filter out all AIS NMEA messages also input to kplex and output via signal K to OpenCPN.

1. If I set up a serial connection and assign it to kplex, where it could be filtered, it is automatically treated as an input, which is not what I require. I have tried editing that in the advanced setting to an output but have only managed to hang the kplex process in doing this and get no output to the usb to NMEA dongle.

2. If I assign it to NMEA output, I assume from the connection diagram that this assignment is to the signal K server and hence that would get all data output from kplex on localhost:30330, which includes the AIS data. When I do this I get output on the serial dongle but there seems to be no way to filter this data.

3. It was suggested I could output to serial via OpenCPN which would allow filtering but this is not an ideal solution as I only want OpenCPN as a backup to isailor/iPad in the saloon.

So my questions are:

1. Can I assign a serial output to kplex? Maybe my problem was editing a GUI setting rather than creating a new one; or


2. Can I filter data in system K to the serial output?


  Openplotter actions, add trigger doesn't do anything
Posted by: NaturalBornCamper - 11-02-2018, 11:23 PM - Forum: General discussion - Replies (4)

Hello, when trying to add actions in openplotter, I can't add triggers as the "ok" button does nothing. Even using a simple date trigger and clicking "ok" does nothing and the trigger window stays open, without any errors or feedback. Anyone encountered this before?

Thanks,

Marco

I added support for this driver but, out of the 3 I have ordered:

  • Reverse half speed with a lot of heat.
  • No reverse
  • Both directions work perfect, but no current sense output.
So all three defective.  I am not very interested in this part anymore unfortunately.  Would have been a nice solution to reduce the needed solder connections.   It does make a lot of heat at 20khz ultrasound frequencies so must be run slower but maybe it it defective in this way too.

If anyone has fully working parts let us hear about it and where they were obtained.  I have no doubt good versions of this part will work.


  Control backlight
Posted by: NaturalBornCamper - 10-31-2018, 12:00 PM - Forum: How do I...? - Replies (2)

Hey there,

Controlling the backlight of the official raspberry pi screen is easy enough on raspbian, but it looks like it's different on openplotter.

The file and folder to use in the link do not even exist and you don't have write permission:
https://raspberrypi.stackexchange.com/qu...en-display
Same with the python code.

Anybody figured it out?


  iAIS
Posted by: Newt2u - 10-31-2018, 11:29 AM - Forum: How do I...? - No Replies

Anyone out there using iAIS?

I am having difficulties connecting openplotter to my digital yacht iAIS receiver. Have set up a TCP connection for the correct IP and port (169.254.1.1:2000) but no connection is established on iAIS (green light flashes slowly).

I know iAIS only supports one TCP connection and it works on my ipad/isailor setup. However even when I power off ipad and reset iAIS, I still can not make a connection to openplotter. Have tried in both client and AP client modes.

Any help gratefully received.

Hi,
I don't have access to a Kindle, but I am wondering if the browser in a kindle could display KIP over WiFi?
