Should i use the Z-wave.me or Z-wave JS integration with Home Assistant ?

-
Image
The short answer is that if you have a  Z-wave.me adapter and are using their Z-wave.me server you shall use the  Z-wave.me integration . On the other hand if you want to use the latest updated software, for your Z-wave.me product, or almost any other , use the Z-wave JS server together with the Z-wave integration . This post will show how to set up the integrations interfacing a standalone  Z-wave.me server  and a standalone  Z-wave JS server

Z-Wave JS UI standalone server on a Raspberry Pi or Linux computer

-
Image
Instead of buying  a new Z-Way adapter I thought it would be a nice project to reuse the almost 10 year old RaZberry 2(RZ) adapter together with a Raspberry Pi 2(RPi).  After some Googling I found  Z-Wave JS UI (ZUI) which is both the server part and an UI. The described installation could be used for almost "any" Z-way interface, impressing list ! , and for "any" Linux distribution.

Updated 2025-10-16 ! 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. 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.

Raspberry Pi watchdog made simple

-
Image
Updated 2025-10-15 for Trixie ! The purpose of a watchdog timer(WD) is very well described here but a more practical answer is; If your Raspberry Pi(RPi) "freezes", or hangs, it will automagically reboot within a very short time. This is made with a combination of hardware and software which is all ready available, on the RPi, and just have to be enabled. After some hours Googling and testing these are my findings !

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... 😉

Node-Red & Mosquitto quick install, Linux, Ubuntu, Raspberry OS

-
Image
Updated 2025-09-08 ! A fantastic way to distribute data between devices is using MQTT . In this post I will do a quick and simple setup with Node-Red(NR) and the Mosquitto(MQ) broker on a Linux machine. Very short, the Broker , installed on a server, handles incoming Publishing and Subscriptions from clients. Every published  Message is "linked" to a Topic.  All Subscribers use a  Topic to "link" to the right Message . How to install Node-Red(NR)  is found here  and the MQ manual here .

ZeroTier Tutorial: Secure Remote Access to Home Assistant & Ubuntu Server + Desktop

-
Image
For a long time I have checked for a good solution to reach my servers at home. My  thoughts   now have finalized in the VPN solution Zero Tier(ZT) where I reach Ubuntu desktop with "RDP" and Ubuntu server with "ssh". The ZT solution also works great with the Home Assistant(HA) browser access and the HA Mobile App. Until now I have used remote.it but ZT will manage all of my network resources as if they were on the same LAN . The Ubuntu desktop installation is running a Linux KVM with HA and an Ubuntu server Lite as  guests .  Setup here .

GPS tracker, GT06, easy setup !

-
Image
  I really like the products on AliExpress and Alibaba, but in most cases the documentation is very simple and to short. So when I bought a combined tracker and a burglar alarm, to our boat, I really tried to get the best. One important thing was that, if possible, getting a lifetime app support. The purchase went well and 14 days later it arrived in Sweden.

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.

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
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. 😉

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)  ?

NetworkManager UI and access point, hotspot

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.
