Building your own magic mirror is a gratifying experience, and the result is an unobtrusive piece of furniture; and a visual part of your smart home. Open source projects such as MagicMirror²<\/a> may assist you in creating your own custom smart mirror interfaces.<\/p>\n\n

It only takes an afternoon to create your own plugin, if your are familiar with JavaScript and Node.js, and takes additional 1-2 hours of testing.<\/p>\n

A MagicMirror² module idea<\/h2>\n

I regularly take out my trash, and from time to time forgot to, or did not know for sure, which type will be disposed at a specific date. What I hoped for, was, that the city I live in exposes a live calendar f.e. a calDAV server, that allows you to access the required data without relying on email, a third party app, and another ecosystem I did not want to subscribe to. Well, the city government had not offered its citizen this service. The ironic thing is: They have a public accessible API, that provides this kind of data.<\/p>\n

Initialize the MagicMirror² module<\/h2>\n

A MagicMirror² module consists of a core module script, to display the data, and a node helper script, to handle the background tasks required....<\/p>","tags":["featured","JavaScript","MagicMirror","Node.js"],"image":"\/user\/pages\/02.blog\/a-magic-mirror--module-to-target-wuerzburgs-opendata-api\/magicmirror-wuerzburg-opendata.webp"},{"title":"Create a Grav CMS cookie consent plugin using PHP","date_published":"2024-08-08T13:08:00+02:00","id":"https:\/\/hanjo.dev\/de\/blog\/create-grav-cms-php-cookie-consent-plugin","url":"https:\/\/hanjo.dev\/de\/blog\/create-grav-cms-php-cookie-consent-plugin","content_html":"

Grav CMS is such a lightweight and convenient content management system for building your own blog or portfolio page. It offers freedom to beginner and intermediate+ backend engineers to make adjustments according to their needs.<\/p>\n\n

As a flat filesystem based CMS building your own theme or plugin is unsurprisingly simple. In this article I'm gonna share my experiences in building your first Grav CMS plugin.<\/p>\n

Prequisites<\/h2>\n

What you need for building your own Grav CMS plugin, is of course an up-and-running Grav CMS setup. I am fully satisfied with a buildup using docker and docker-compose and a minimalistic docker-compose.yaml<\/strong> configuration file.<\/p>\n

---\nservices:\n  grav:\n    image: lscr.io\/linuxserver\/grav:latest\n    container_name: grav\n    environment:\n      - PUID=1000\n      - PGID=1000\n      - TZ=Etc\/UTC\n    volumes:\n      - $PWD\/grav\/config:\/config\n    ports:\n      - 8090:80\n    restart: unless-stopped<\/code><\/pre>\n
Running docker-compose up -d<\/code> exposes the desired services on port 8090 of your host system and the admin panel is accessible via localhost:8090\/admin<\/a>. After completing the basic setup, you are almost good to go.<\/p>\n
Grav CMS provides its own package manager<\/a>, which makes it easier to manage new themes or plugins.\nYou gain access by punching in docker exec -it -w \/app\/www\/public grav bin\/gpm<\/code>. <\/p>\n

Dynamisches DNS ist sehr hilfreich, um auf Ihr lokales Netzwerk zugreifen zu können, wenn Sie nicht zu Hause sind. Dieser Artikel zeigt, wie Sie Ihre porkbun.com DNS-Einträge verwalten und mit Hilfe von Home Assistant mit Ihrem lokalen Netzwerk synchronisieren können.<\/p>\n\n
Es ist eine fantastische Idee, zu Hause eigene Cloud-Dienste einzurichten, die digitale Freiheit zu nutzen und die volle Kontrolle über die eigenen Daten zu haben. Aber um Ihre Cloud, Ihre Passwörter, Ihr Smarthome oder Ihre Automatisierungen verwalten zu können, muss Ihr kleiner Server in Form eines Raspberry Pi, Odroid oder eines ähnlichen Geräts von der Außenwelt aus erreichbar sein. <\/p>\n
Wahrscheinlich aktualisiert Ihr Internetprovider Ihren DHCP-Lease einmal pro Tag und weist Ihrem Netzwerk eine neue IP-Adresse zu. Um ohne Rätselraten auf Ihr Netzwerk zugreifen zu können, ist es empfehlenswert, eine eigene Domain oder Subdomain zu haben, die auf diese Netzwerkadresse verweist. Ich zeige Ihnen, wie Sie die DNS-Einträge Ihrer bei porkbun.com registrierten Domain über Home Assistant und die Porkbun API<\/strong> aktualisieren können, und Ihre aktuelle IP zuzuordnen.<\/p>\n
Natürlich gibt es viele Möglichkeiten, DNS-Einträge zu aktualisieren (ddclient, benutzerdefinierte Skripte, ...), aber ich habe mich für Home Assistant entschieden, weil ich die Änderungen leicht mit der Home Assistant-App oder sogar mit dem Telegram-Messenger...<\/p>","tags":["featured","home assistant","smart home","dynamic DNS"],"image":"\/user\/pages\/02.blog\/use-home-assistant-to-dynamically-update-your-porkbun-dns-records\/homeassistant-porkbun-flow.webp"},{"title":"Attach and setup a filament runout sensor for your Ender 3 V2","date_published":"2024-05-04T09:46:00+02:00","id":"https:\/\/hanjo.dev\/de\/blog\/attach-and-setup-a-filament-runout-sensor-for-your-ender-3-v2","url":"https:\/\/hanjo.dev\/de\/blog\/attach-and-setup-a-filament-runout-sensor-for-your-ender-3-v2","content_html":"
Adding a filament runout sensor to your Ender 3 V2 setup increases the success rate of your 3d prints, and keeps your mid-print models alive, when your filament breaks or runs out.<\/p>\n\n
Due to a lack of storing my filament spools appropriately, I often had issues regarding moist filaments, and it did not help that my filament takes a long way until it reaches the hotend. My prints occasionally started with fragile filament, which resulted in broke and stuck filament after a few layers of printing.<\/p>\n
What you need<\/h2>\n
To reduce those filament troubles, I decided to upgrade my Ender 3 V2 to support filament runout monitoring directly. <\/p>\n
And this is what you need:<\/p>\n
