Use Claude AI in Home Assistant Studio

Published on February 4, 2026.

Sometimes you have to configure stuff in Home Assistant the "painful" way: Working with Yaml-Files instead of using the UI. Therefore Studio Code Server is the first choice for most of us. But Yaml isn't fun. Yaml in hass.io especially isn't fun.

But there is ai for the rescue. AI isn't always the solution, but working with ugly configuration formats is exactly where it is good at. So let's add claude to the Studio Code Server

Make Videos work with DaVinci Resolve on Linux Mint

Published on November 22, 2025.

Installing DaVinci Resolve on Linux Mint takes a few steps. But at the end it simply works after you have done those.

I tested those on Linux Mint but should work on most Ubuntu - based Distros.

I mostly followed the instructions from virtual curiosities and just added a few of my own addition...

Grafana - Notifications for Mastodon

Published on November 22, 2025.

Grafana is a very useful tool for monitoring your own programs, discovering silly bugs, or simply looking at beautiful graphs :)

Another feature is "Alerts". These can be configured arbitrarily, whether high CPU load, too many errors in the log, or similar should trigger an alarm.

This post won't be about the alerts themselves, but rather about sending already configured alerts to Mastodon. These are called Contact Points in Grafana and initially don't offer Mastodon integration. However, this can be worked around with a few simple steps.

Automatic Blogpost translation with Claude.ai

Published on November 22, 2025.

To be completely honest: I do not really like automatic translations. Especially if you are not born in an english-speaking country, translations have been a real pain from the beginning. MSDN was one of those contenders that did really, really bad translations, years before AI was something to talk...

Led Progressbar for 3d Printing

Published on November 22, 2025.

3D printing can be fun, but can also be very annoying if something bad happens. So I wanted to have an easy indicator if something goes wrong without having to check the print every few minutes

WLED to the rescue

My 3D - Printer is in a small room. I usually do not have to enter that room until...

Vibe Coding: An experiment

Published on November 22, 2025.

Before I begin to even start writing about this topic I assume it makes sense to mention that this article has not been created using AI. Not a single word. (with one exception: The german version has been translated automatically using Claude, like all entries on my blog) I also tried to write t...

Setting single Panels on NanoLeaf using Home Assistant

Published on January 20, 2024.

I went deep into Home Assistant automation currently and - as everybody knows who ever went this road - more ideas came up. So my newest idea was to use the Hex-Panels from Nanoleaf to display some information. For example if the washing machine is ready, I have an appointment, the Smartphone Batter...

How to track a squirrel

Published on December 17, 2023.

[Disclaimer: This is not meant as a tutorial, more as some chitchat. You can find the source on github nonetheless, but I assume this is a VERY specific use case noone else uses]

Let's start by telling you that this whole project ist utter nonsense. Noone really needs this feature. I decided to...

Raspberry Pi 4: usB first!

Published on May 27, 2020.

At the time of this writing the boot-from-usb has just been made available as a Beta feature for the Raspberry Pi 4.

Hi,. folks,

Two Apps at the same time: Deploy SharePoint Add-In to Cloud AND On-Premise

What the fuzz is this about?

I am not absolutely sure if I am the first one who did this, but it seems at least noone else wrote it down until now. :) We hat a customer who liked our Office365 Provider-Hosted App "Mydea", but wanted us to install that on his SharePoint 2013 - Installation. In Germ...

Wayback Machine and 301 redirects

Published on November 15, 2016.

As you might know: the wayback machine from archive.org saves snapshots of websites. It does this automatically or can be forced to do so. However. If you ever had a 301 redirect on your site you are very much doomed.

Like browsers also the wayback-machine caches the redirect and does not continue...

Getting rid of Proxy limitations using Fiddler

Published on September 16, 2016.

If you work in a company that uses Proxy authentication (aka forces you to enter a password to access websites) and are a developer you know my pain: Some Most applications just don't really like proxies. Visual Studio itself for example does not like proxy authentication at all and responses with a...

Displaying Data from HomeMatic Actors on a WebInterface

It's because they at Microsoft hate web developers

Published on June 14, 2016.

That remark isn't mine, it is from StackOverflow. :)

I had an issue that my Office365-App did not work correctly on the machine of ONE user. Sadly though that user was the Microsoft validation crew. I was unable to reproduce the error and did not even see any clue in the Server logs. Everything se...

Detecting Smartphone via Bluetooth on Linux (Raspberry Pi 2)

Published on February 27, 2016.

After detecting my phone using WiFi (which does only work under Marshmallow while the phone is loading or the display is enabled) and detecting the fitbit device I came back to my original task to detect my phone using Bluetooth.

While there are many documents out there that describe this...

Tracking fitbit presence under Linux (Raspberry Pi 2)

Published on February 27, 2016.

As I wrote before I track the presence of my smartphone using WiFi. Since Android Marshmellow this doesn't work anymore, because when switching to idle mode, the WiFi is disconnected. The easiest way to get around this issue would be to use Bluetooth instead. And in fact: I already decided to go th...

Switching the LED of a surveillance cam on and off using Linux

Published on January 15, 2016.

I already wrote a script on my Raspberry that starts and stops the surveillance mode of my camera using the "Surveillance Station" on the Synology DiskStation. Now I wanted to extend that tool and light the LEDs of the cam when it is recording and turning them off if it isn't.

This has two reaso...

Control your Harmony Hub with a Raspberry Pi (Linux)

Published on January 15, 2016.

So my surveillance cam now only records when I am not at home. But what if I forget to turn off the TV? That should happen automaticly, too! But fear not: There is a solution - at least if you own a harmony hub. With the help of the "HarmonyHubControl" - tool (written in c++) this is done quite eas...

Automate your Synology Surveillancestation with some simple Linux - commands

Published on January 7, 2016.

I own a Synology diskstation which has the "surveillance station" on board which records content from any LAN (or WiFi)-enabled webcam and sends an alarm when someone is moving at my home. It is possible to enter time schedules when the camera should be enabled and when it shouldn't. But that does n...

SCRUM and Git: Optimized Gitflow // with a lot of fancy colors :)

Published on March 4, 2015.

For a lot of teams, GIT is the first choice for maintaining the code. So it is for mine. But this post isn't limited to GIT and should work with SVN or TFS with little modifications, too.

Why is the Git flow important when using SCRUM?

Aren't those just two worlds, anyway?

Well. Kind of. But w...

IMAP-HTML-Autoresponder with PHP

Everyone knows spam. Everyone hates spam. And everyone who has his email-address written on the net (for example in the NIC-records for a domain) gets a lot of spam.

I am one of those guys who gets a lot of spam. Of course there are anti-spam solutions out there, but the best would be to not e...

Emptying SharePoint-List the (quite) fast way

Published on August 10, 2012.

I already offered a solution to empty a SharePoint list at light speed

But this solution hast two big disadvantages:

1. You cannot empty a list that has more entries thatn the allowed list view threshold (default is 5000)
2. All Lookups will be lost

This solution has non of those drawbacks. I...

Emptying SharePoint lists the ultra fast way

Published on August 9, 2012.

SharePoint is damn slow when deleting lines from lists. Each entry can take up to some seconds which isn’t nice when you have to delete thousands of lines.

Also no Trunc-Methode is available.

Other solutions found on the net creating xml-files to bulk delete aren’t very fast either.

That’s why...
