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.

Beeing forced to use a hearing aid(HA) is not that fun but on the other hand it's always exciting with new electronic gadgets and to better participate in conversations with other people.  In this post I will just summarize some points gathered when setting up the HA with the ReSound Smart 3D (S3D) app in an Apple environment. But of course there is also a Android app These hearing aids are compatible with the mentioned app and I'm using Resound Nexia 9 RIE .

Receive temperature, 433 MHz sensors, with RTL-SDR

-
Image
  Updated 2024-12-01 ! In my underfloor heating project, using Node-RED, I have to have one sensing thermometer per room/zone, seems to be 8 in total, so therefore it would be nice with a wireless battery sourced device with good resolution and frequent updates. During the test phase I used a Z-way device but the resolution was pretty bad. Another device mentioned is  the  Ruuvi tag  but since it's a bluetooth device the transmitting range could be better. After some googling I went for 433 MHz devices.

Matter bridge, with Shelly, or non Matter devices

-
Image
Matter is a smart home standard currently being developed by a consortium of over two hundred companies, including big players such as   Apple ,   Google ,   Phillips ,   Amazon   and   Samsung . Many new devices have Matter implemented, from the beginning, but devices, such as most of Shelly devices don't. On the other hand many hubs can be upgraded to Matter support. For example an Apple TV. With a Matter bridge  you can solve the incompability. This post will use  Matter bridge plugin Manager and the Shelly plugin  but it could be other devices shown in the picture below.

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... 😉

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

-
Image
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)  ?

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.

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. 😉

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.

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.
