If you have a RPi 4, 5 and a USB SSD or other USB drive, that works as a boot media, just use the RPi imager which can write the image direct to the USB storage.

IVT, Bosch heat pump easy integration, Home Assistant
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.

Home Assistant core install, Raspberry Pi and Python 3.12
It works very well and here are the install instructions.
On the other hand if you want to add HA to a RPi which you already have up and running, without Docker, you need to install something which is called "Home Assistant Core".
Please check the "Remarks" below before you start.

Clone the Raspberry boot disk
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.

Install Weather34 with WeatherLink, v2 API
Updated 2024-01-08 OK with Bookworm 64 bit, PHP 8.2 !
This post is an update from a former post which handles on how to set up a weather WEB-site with data from Davis Weather Link(WL) but here adapted to the latest WL API v2.Any product that reports weather data to WL can be used as a source for this weather template.This is made without additional software such as Cumulus, Weather display or the Meteobridge product.

RPi install Apache/PHP WEB-server
As a part of one of my project, the ultimate Weather site ? Weather34, I needed a WEB-host with PHP.
I started up with a fresh Raspberry OS Lite SD Card with Samba installed.
Log on, with ssh/terminal to the RaspberryPi(RPi), in this case hostname "pws01", and update the OS with
sudo apt full-upgrade -y
sudo apt clean
sudo apt install apache2

AIS receiver & dispatcher with OpenSeaMap
The application showing the map is SignalK, (SK) a OpenSource project for marine use.
With the "ais-forwarder" plugin you could send/dispatch the NMEA AIS data to Marinetraffic or Vesselfinder. Another AIS-dispatcher.

NMEA WiFi gateway
I have searched for a solution transmitting the NMEA data, from the
navigation network, via WiFi, to for example iSailor or other Tablet/Phone applications.
Most of these applications just accepts NMEA0183(N1) but many boats are also using SeaTalk 1(ST1) and NMEA2000(N2K).
This post will cover, kept compact, my best findings covering both a DIY
and a commercial approach to handle the different protocols.
