Im using NodeRed together with  Speedtest by Ookla  but just the other day it wasn't showing the right data so it was time for "Bredbandskollen", the command line version. Bredbandskollen has always been a reliable source when testing internet speed.  I'm using their WEB-site and the iPhone app and it have always worked very well. This post will show how to plot data in a graph according to the picture.

Just the other day the backlight for our classic Raymarine E 120, Navigator(MFD), stopped working. It's from 2006 so I'm not surprised that things happen. You may wonder why we keep it instead of buying a new one but the thing is that we have 2 installed together with a well functioning radar so buying new stuff will be a hefty price tag. After some Googling I found out that the backlight is produced by a CCFL , a type of neon light, and can give up after some years. The Googling also gave some tips how to change to a LED backlight. The picture above is showing a test with a short LED light strip to verify the solution, with dimming working, and checking the health of the MFD.

Updated 2024-05-03 ! In Signal K (SK) there are 2 applications, in SK appstore, that can handle charts Freeboard SK (FSK) Tuktuk Chart Plotter (TT) FSK, preinstalled, uses the OpenSeaMap charts(OSC)  when you are online.  If you want to use offline charts or other chart resources you have to install " @signalk/charts-plugin "(CP)

In search of the optimal solution on how to interface our IVT Heat pump,   first try here , I stumbled over   a nice integration   for Home Assistant(HA). A first quick setup is shown at the right. The first obstacle was that it was HA which I knew about but never used.  So it was "back too school" and doing  a blog post  about a HA Core install.

If you are running the IVT Anywhere or the  Bosch Easy remote  app you probably also can  retrieve its data with for example NodeRed.  With the nice application  Bosch XMPP you can set up an integration with the cloud service supplied by your vendor.

Updated 2024-03-01 ! OpenPlotter(OP), a Boat Navigation application, is really a nice and simple installation of OpenPlotter (OP) OpenCPN (OC) SignalK (SK)  and other supporting applications for Your boat. An overall information about the OP package is found here . Install guide for the new stable OP, version 4, is found here .

Updated 2024-02-20 ! A very nice way to fix a backup is to make a copy, bootable, of the actual SD card You are using on the Raspberry Pi(RPi). This will be done even when the RPi is up and running ! This application can also be used to make a bootable SSD or USB drive !! You clone from the command line so You don't need the standard GUI, Pixel, and the " SD card copier "  function. It is also possible to set up a a scheduled job, cronjob explained later, which for example makes a clone every night at 1 o'clock.

Updated 2024-02-08 GRIB is a data format , used for meteorology, to store historical and forecast weather data.  The use case for me was analyzing forecast data, from GRIB files, so an early warning could be rised before a high water level or coming storm appears. This could then be used at our weather site . There are several applications , also ones that visualizes the data, but this post will handle how to extract data from files using command line. Forecast without GRIB files ? Check this API for Europe.

I have used the TP-link Deco M9 for quite a while and it have worked very well. Since almost 2 years I have used mobile broadband as a source for the Mesh network, at home, via a   Nokia Fastmile (NF) with no direct flaws. Getting a very nice offer, half the monthly cost, for mobile Internet from our mobile phone  operator it was time to test something new. Since I probably will have to return the Nokia receiver quitting the old supplier I had to test the new provider with some other equipment. Running the Teltonika RUT 240 (TR) in our yacht, in the summertime, it was available for testing.
