Updated 2026-09-01 As a part of one of my project,  the ultimate Weather site ? Weather34 , I needed a WEB-host with PHP. Log on, with ssh/terminal to the host,  in this case hostname "pws01",  and update the OS(skip " sudo " if using " root ") with sudo apt update sudo apt full-upgrade -y sudo apt clean go on and install the Apache server with sudo apt install apache2

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 !!

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.

Davis WeatherLink weather template, v2 API

-
Image
Updated 2025-11-01 ! I have written a post with the same subject before, also using NodeRed (NR), but this post is using the latest WeatherLink v2 API instead of the v1 API .  The v2 API supports more devices and now also including the old ones. If You want a more advanced weather site  this is  a very nice one coded in PHP also using the v2 API.

GRIB files and extracting data, Linux, Raspberry

-
Image
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.

Calculate wind using U and V GRIB components, NodeRed, JS

-
Image
Updated 2022-11-28 ! In a former post I showed how to download and extract data from forecast GRIB files but avoided to handle if the wind direction and speed was declared as U and V components, vectors.  In this post I will extract wind data from a GRIB forecast file and use the U V components to calculate, and display, wind speed and direction at a chosen point. The data is visualized as graphs in a NodeRed dashboard. Normally, using charts in NodeRed, the timestamp is taken from the time when the input message is created but here I will use the timestamp from the forecast, loading the whole chart in one go.

Davis PWS linked to pwsweather.com

-
Image
If you are using Davis Personal/Professional weather stations (PWS) you will get a nice dashboard when you link your PWS to the Davis weatherlink (WL) site. What you probably really miss is a forecast displayed together with your PWS data. The picture is showing a part of the dashboard at pwsweather.com (PW) after you have linked your PWS to the site. An add on is that you via API:s can get both the current weather, forecast and other data free of charge, via the aerisweather.com (AW) site. This post will handle the setup and also a Node-Red dashboard interfacing the aeris API.

Davis weather station, WeatherLink, PHP

-
Image
Updated 2021-12-05 ! In the harbour we are using a Davis weather station , Vantage Pro2, as our PWS(Private Weather Station). If you like to display the data, online on the web , you can use the Davis service,  Weatherlink (WL) where you register an account.  Another way is to retrieve the weather data as XML or JSON, from the Weatherlink web-site, and use it in your own application  (open source!). Another approach with NodeRed could be find here .

SIGNL4, automated alerting with free mobile app

-
Image
I'm involved in several projects where you, as quick as possible, want to get an alert if anything fails. After a lot of Googling I found SIGNL4 . They have several ways to create an alert , can involve a team, have a nice app and is free, up to 5 users, if you use the "STARTER" option . In this post, as an example , I will show how I detect if my AIS receiver/dispatcher stops receiving AIS targets, sent to Vesselfinder , and how an alert is forwarded to the SIGNL4 app. I'm using NodeRed on a Raspberry Pi to realize the function

WeatherLink weather template

-
Image
Updated 2022-02-21 ! If You are interested in building Your own weathersite with information from Davis Weatherlink(DWL), and don't are a skilled programmer I can really recommend Node-Red(NR). In this post I give an example how to start with the NR dashboard GUI and DWL V1 API. !! Please note new version with the latest v2 API !! If You want a more advanced weather site/template  this is  a very nice one coded in PHP.

HomeKit with "ANY" temperature source

-
Image
From AppleWatch As long as it's possible to retrieve information, in some way, from a sensor OR a website/webserver, with temperature information, it's possible to show it in HomeKit with HomeBridge (HB). In this post  NodeRed (NR) is retrieving the temperature from Your selected source and is also acting  as the WEB endpoint   for  the HB  " homebridge-http-temperature " plugin . In my case I wanted an outside temperature so used the measurements from our Davis Weather station and their  JSON REST API but it could for example be Your Raspberry CPU temp  or showing the speed of Your Internet connection.

Weather34 & WeatherLink w/o cronjob

-
Image
Deprecated !!  New approach  here  !! Running Weather 34, W34, using my setup , the program " cumulusdata.php " is fetching data from Davis Weatherlink(WL), and are writing the data to a file, type Cumulus. The old way was to fetch the data via a scheduled cronjob.  Doing a small change to " windspeeddirection.php ",  " updater.php "  , and using  the latest version of  " cumulusdata.php ",  will do the update with the built in W34 refresh routine instead of cron job. Thanks to Ken who gave me the hint.

Installing Ubuntu 24.04 or 26.04 on an old MacBook Air(2011)

-
Image
 Updated 2026-07-09 ! 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 latest LTS (UOS) ! (Above link is now UOS 26 LTS which I have not tested) Ubuntu on  Mac Mini (2018) and MacBookAir (2010)  ?

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.

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

-
Image
 Updated 2026-07-05 !  After testing Home Assistant (HA) for a while, I’ve realised it could improve my home automation, despite that I'm mainly 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 !   😀

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

-
Image
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... 😉

Clone the Raspberry boot disk

-
Image
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.

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.

Updated 2023-10-12 ! In a former post I shared some thoughts about how to start using NetworkManager (NM), on a Raspberry, and here I will continue with additional examples that can help with network setup. NMTUI is NetworkManager text UI which can handle the most common tasks in a easy way. An access point or hotspot will be configured. " sudo nmcli connection edit xxxx " is a command that guides you throw a change of parameters.
