DYI Weather template with data from Davis Weatherlink

-
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 upgrade the app using ChatGPT and Gemini. Burt several hours later I gave up !!

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. Please note !  that this app, 2026-03, doesn't work with Node.js V24 but there is a "work around". Check below.

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.

Ubuntu Desktop for beginners or easy start !

-
Image
Updated 2026-03-25 This post is for both Windows and Mac users !   I have been running Linux, Raspberry Pi OS , since several years but almost just the Lite version (without Desktop). But when my old MacBook Air "gave up" , with Mac OS, it came naturally to use Ubuntu Desktop since it's also based on the Debian Linux distribution and the most used Linux distribution. So it ended up with installing Ubuntu 24.04.4 LTS (UOS) or the later 25.10 !

Node-Red quick install

-
Image
Updated 2026-03- 15 ! Node-Red (NR) is  Flow-based programming for the Internet of Things This post isn't made as a complete install guide, there are several, just some links to the best information I have found. The best thing is that even if you don't are a skilled programmer, but like logic flows, you can make really advanced things. It's pre-installed on some Raspberry Pi(RPi) distributions. Running  Node-Red with  multiple instances  ?

Home Assistant DIY, ESPhome, creating a Bluetooth proxy !

-
Image
My  Home Assistant (HA) server setup is  virtualized   with  Linux KVM  and I needed a solution handling  Bluetooth  since the used  Mac Mini  just had a PCI connected one. HA recommends to use a  Bluetooth proxy (BTP) quote  " since Linux kernel updates have previously broken Bluetooth functionality and Bluetooth driver support Linux generally falls behind other operating systems for newer adapters. A Bluetooth proxy is particularly interesting to users who virtualize their instance, where the USB pass-through may cause additional problems ". So using  ESPHome  I will set up a BTP in this post !

Home Assistant with VirtualBox or Proxmox or Linux KVM ???

-
Image
Updated 2026-02-24 ! After testing Home Assistant (HA) for a while, I’ve realised it could improve my home automation, despite that I'm using Apple HomeKit. When I tested HA with Node-RED and some other "Add-ons", on a Raspberry Pi 3 (RPi), I found that its resources wasn’t enough. The following setup could be any computer but I recently bought an Apple Mac Mini M4, replacing my 2018 (M18) model, so the M18 was really a great candidate for my HA setup. The preferred method running HA is through the  HA Operating System (HAOS), which makes your "life" easier. 😉

iCloud drive sync, or mount, with a Linux, Ubuntu, device

-
Image
Updated 2025-01-23 ! With my project to keep a MacBook Air 2011(MBA) alive , Ubuntu installed, i searched for a solution where my iCloud drive(iCD) was  continuous synced with my MBA. This must work both ways so even a file change made on MBA should be replicated to iCD. rclone now, 2025-01, works with iCloud !! Setup below !! Before "rclone" was working with iCloud I solved my sync between iCD and MBA with Syncthing (ST). Check below. ST doesn't sync with iCloud so the work around here was to use my MacMini, Mac OS, as the "Middle man". It's always on and synced with iCD.

Raspberry Pi OS Lite with GUI, RDP, VNC, Chromium

-

Updated 2025-10-02 ! I like the Raspberry Pi(RPi), with Raspberry Pi OS Lite (no Desktop is included), headless operation, and then adding the software You need. Until now I haven't had a use case where I needed a Desktop but now was time.  Why don't use the Raspberry Pi OS with Desktop ?? In that package there is a lot of software I don't need and I really want to optimize the RPi. I think that the less software You install the happier RPi will be... 😉

Installing Ubuntu 24.04 or 24.10/25.04 on an old MacBook Air(2011)

Updated 2025-05-20 ! I have done several posts Blogging about how to keep an old MacBook Air(MBA), mid 2011(A1369), with SSD disk "alive". I have used the fantastic software package OpenCore Legacy patcher to upgrade the Mac to the latest Mac OS.  A while ago i tested Mac OS  Sequoia (15.3), on the mentioned Mac, but I had to admit that it was to much for the 14 year old companion. I really like the Mac and everything works, after a battery change , so it ended up with installing  Ubuntu 24.04.2 LTS  or if you want the latest scroll down and get Ubuntu 24.10/25.04. Ubuntu on  Mac Mini (2018) and MacBookAir (2010)  ?

Updated 2024-06-06 ! After having tested several methods creating a bootable USB SSD, or other USB drive, for Raspberry Pi(RPi) 3 4 and 5, I finished with this simple method Create the setup you want on a ordinary SD card(Or use existing) Make a bootable backup/clone of the SD card saving it to the USB SSD Remove the SD card and boot from the USB SSD Having a RPi 4, 5 ? Use this post on how to write the OS direct to the SSD.

SeaTalk1 to NMEA 0183 converter, DIY

-
Image
Updated 2024-08-30 !  !! Another SW solution is available for RPi 5 here !  using the same HW. Thanks to Thomas, (the guy with the nice marine interface board ) ,  it's now possible  to decode, one way, the SeaTalk1(ST1) sentences in a pretty simple way. You just  use OpenPlotter(OP) and/or SignalK(SK) and an  Optocoupler . The thing that made it, is that Thomas   has released a "how to" and  Python source code , that will read the data from a GPIO pin on the Raspberry Pi, (RPi), and format it so the standard parser in SignalK can translate it to SignalK delta format. It is then  available as NMEA 0183. It's even possible to send the data in to a NMEA 2000 network, with a proper hardware interface.

Clone the Raspberry boot disk

-

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.

Waveshare CAN hat with Signal K & OpenPlotter

Updated 2024-07-08 To get information from the NMEA 2000(N2K) network, to the RPi, I have been using  Actisense NGT-1 , for a long time,  and later also the  Yacht Devices YDWG 02  but now it was time for a Raspberry Pi(RPi) CAN hat(CH) from Waveshare(WS). WS have 3 different models but I picked the 2 channel isolated one . It's recommended to use an isolated one which also is demanded for those interfaces which can be approved by the N2K group.
