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 !!

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.

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.

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.

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  ?

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 !

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. I have converted to HA running on Proxmox !   😀
