Bei IKEA gibts einen Feinstaubsensor (PM 2,5) für 10€ und mittels eines ESP8266 kann man den Wert per MQTT weiterleiten. In meinem Fall also an FHEM und somit ist der schön ins Smarthome integriert. Einen ESP8266 hatte ich noch rumliegen. Hier das Repository bei GitHub: https://github.com/Hypfer/esp8266-vindriktning-particle-sensor Mittlerweile gibts auch ein gutes Youtube Video dazu: https://www.youtube.com/watch?v=NwHL8XMarFY Und hier noch ein Bild davon, wie es bei mir aussieht: https://resize2fs.de/blog/how_i_do_my_computing/ Tue, 16 Mar 2021 18:02:16 +0100 https://resize2fs.de/blog/how_i_do_my_computing/ As almost every geek, I want to show you my equipment and setup. Software I use Debian GNU/Linux as Operating System whenever possible. But some of my servers are based on CentOS, which has a simple historical reason. See my about page for more nice software that I really like. Internet and Phones A pretty normal Fritzbox 7530 do I use as DSL router and telephone system. My fritzbox routes everything to my opnsense installation on an APU3 board. https://resize2fs.de/blog/building_a_storage_multimedia_server_part2/ Sun, 14 Mar 2021 20:21:29 +0100 https://resize2fs.de/blog/building_a_storage_multimedia_server_part2/ Finally all parts recieved and I found some time to assemble everything which worked perfectly, no issues at all. I prepared an usb drive with latest debian 10 netinstall and started the installation. During the installation, I learned that with those NVME SSDs, legacy boot is no option anymore, so it was my first time installing Debian in UEFI mode. I read some different discussions on whether to put the /boot/efi on a RAID1 or not. https://resize2fs.de/blog/libretranslate/ Fri, 19 Feb 2021 18:33:38 +0100 https://resize2fs.de/blog/libretranslate/ Recently a friend told me about LibreTranslate. I immediatly liked the project and spinned up the new url translate.resize2fs.de and requested a new letsencrypt certificate via acme.sh. I choose pip to install the software. apt install python3-pip pip3 install --upgrade pip pip3 install libretranslate useradd -m -s /sbin/nologin libretranslate And I also create a systemd unit file for the service. cat /etc/systemd/system/libretranslate.service [Unit] Description=libretranslate Documentation=https://github.com/uav4geo/LibreTranslate After=network.target [Service] ExecStart=/usr/local/bin/libretranslate --frontend-language-target de ExecReload=/bin/kill -HUP $MAINPID Restart=on-failure User=libretranslate [Install] WantedBy=multi-user. https://resize2fs.de/blog/building_a_storage_server_part1/ Sat, 13 Feb 2021 09:04:20 +0100 https://resize2fs.de/blog/building_a_storage_server_part1/ For many years (more than 10y?) I had some sort of 24⁄7 server running at home, hosting some nice services like mail, websites and of course central storage. It started with a random intel atom based platform with windows and vmware server. Moving to a single ESXi with windows and gnu/linux based virtual machines and finally moved to a server where I used qemu/kvm with many gnu/linux based virtual machines. https://resize2fs.de/blog/fhem-readingswatcher/ Fri, 12 Feb 2021 16:39:00 +0200 https://resize2fs.de/blog/fhem-readingswatcher/ From time to time, it happens that a battery inside a device dies before updating the battery state to something like “low”. For that case, we can use the FHEM module readingsWatcher. From FHEM commandref: The module monitors readings in other modules that its readings or their times change at certain intervals and if necessary, triggers events that can be processed further with other modules (for example, notify, DOIF). Activate the module with basic usage: https://resize2fs.de/blog/hello-world/ Mon, 30 Mar 2020 14:41:22 +0200 https://resize2fs.de/blog/hello-world/ Hello World!
