Volvo Penta NMEA 2000 Gateway

Image
Updated 2026-06-15 It's always nice to have ALL information at the same place, navigator/plotter, when You are out with the boat.  What could be missing is the engine information/data. If You have a Volvo Penta from 2006 or later it could be pretty easy. There are some "standard" NMEA 2000 gateways to choose from, for example;  Volvo Penta has it's own 22813366, 3889758 Raymarine ECI-100 Maretron J2K100 ..... Since you found this post, check this out => Remote Yacht control  

Apple Time Machine backup targeting Linux or Proxmox LXC

Image
My old AirPort Time Capsule will not work with the new version of Mac OS 27 and since I really would like to have a local backup, besides iCloud, the tinkering started. It ended up with a Linux solution and an external USB disk, 2 Tb. In this post will show "how to" create a target for the Time Machine(TM) backup with a standard Linux host or with a Linux container in Proxmox + a Proxmox backup to the same SSD

OpenPlotter v4 , install guide

Image
Updated 2026-05-22 ! 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 . Maybe you should think twice before installing OP, u pdates don't happen as often as they should and still using Debian 12. So check out Signal K instead !!

DYI Weather template with data from Davis Weatherlink using Claude

Image
I have been very fond of our weather website with the  Weather34 application (W34),  but there is an end to everything..... Doing an upgrade of the server it collapsed and showed a blank screen. I'm no programmer but I had to test if it was possible to update the app using ChatGPT and Gemini. Burt several hours later I gave up !!

Home Assistant and Node-RED

Image
Updated 2026-04-09 ! Node-Red (NR) is  Flow-based programming for the Internet of Things. I have in the past  written a lot of posts  for Node-RED and the   HA implementation  makes it easy to interact with HA:s entities. The best thing is that even if you don't are a skilled programmer, but like logic flows, you can make really advanced things and it really complements the logic that could be made within Home Assistant(HA). In this post I will do a quick introduction to what is possible with NR together with HA.

IVT, Bosch heat pump easy integration, Node-RED

Image
Updated 2026-03-30 ! If you are running the IVT Anywhere or the  Bosch Easy remote  app you probably also can  retrieve its data with for example Node-RED. With the nice application  Bosch XMPP you can set up an integration with the cloud service supplied by your vendor.

DMI forecast API for atmosphere, ocean and sea ice, free !

Image
Updated 2026-03-28 ! DMI is the Danish Meteorological Institute and the   Open Data API provides free and open access to DMI’s data.They are covering a pretty big area not just Denmark . I'm maintaining the weather station for Domstens yacht club and have become really interested in weather "issues". The actual use case for me is that I have to change the mooring, of our boat, if the water level exceeds 60 cm from normal.   For several years I have been searching for a free forecast API so I can get an early warning when the water level rises. Node-Red is used.

IVT, Bosch heat pump easy integration, Home Assistant

Image
Updated 2026-03-27 ! 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. Please note !!! This integration stopped working with HA 2026.3.4 and the XMPP protocol(IVT) !!! But this one still works and can supply HA with data. 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.
