  Update from github in gui
Posted by: joabakk - 03-25-2016, 07:59 PM - Forum: Feature Requests - Replies (4)

It would be great if there was a way to update all the dependencies from the gui, as there are a lot of good things happening these days on kplex, openplotter and signal k

  Analog motor sensors
Posted by: manitu - 03-24-2016, 02:15 PM - Forum: Feature Requests - Replies (12)

Is it possible to connect openplotter to resistive motor sensors?  would be great to get coolant temp, oil pressure , turbo pressure and so on. and stndard tank sensors.

Most sensors operate in a 0-500 ohms range , 10-180 being most common in europe , while  240-30 ohms is most common in the US

here are the faria sensor values:http://faria-instruments.com/site_manuals/IS0085E.pdf

Both 2-wire sensors and one wire (resistance to ground) sensors should be supported , but either one would do.

Come to think of it; what about making a Rpi zero signalK motor interface??

Keep up the great work.


  HTU21D humidity value
Posted by: Swokey - 03-22-2016, 09:46 AM - Forum: How do I...? - Replies (5)

I still have a lot of fun with openplotter. Now I'm using it for a new project (creating mine own drying place for meat).  I allready have tried a lot, but I don't have a solution yet. So if anyone can help me it would be great.

The action/triggers are not a solution because I need to combine several input before I do an action.

I need the output of the humidity from the HTU21D. When I use it with openplotter I see the NMEA sentence with the correct value. So I extracted the code from the i2c.py file with that what I think need.

Why don't get I the humidity?


import socket, time, pynmea2, RTIMU, math, csv

humidity_val = RTIMU.RTHumidity(s3)
humidity_val_b = True




print hum



Kind regards

Bug Calibration failed
Posted by: Didier B - 03-21-2016, 06:20 AM - Forum: Bug Reports - Replies (11)

Hi all Openplotterists !

My config : Rpi2, V7.1beta, connected sensors : MPU9150, BMP180, HTU21, DS18B20 (2)

I couldn't calibrate properly the magnetometers of my MPU9150, Once I got more than 200 counts in each of the counters, I started the ellpsoid phase which terminated quickly, with a message :
      Failed to execute RTEIIipsoidFit.m. Only
      min/max calibration available

I remember having seen a thread on that matter, but couldn't find it ...
2 - I could register on OpenMarine, and posted same thread, which one to favour for bug reporting.

Items to monitor:
All of the below items would have triggers associated with them that would generate an alert (emal or SMS) if a threshold is reached.

  • (2) DC voltages 24 V (or higher?)  What precision?

  • (3) temperature probes (ambient inside, outside, refrigerator) or more?

  • (1) AC mains voltage monitor

  • Lat/Lon of boat

  • (?) digital inputs for bilge pump cycling, refrigerator compress cycling, etc.

  • (4) GPIO that can drive a relay board to turn on peripherals such as Air Conditioning or Heat, bilge pump, lights, etc.
