Earlier this year I have posted an article on how I managed to gather and persist calories from FDDB.info. As I have grown more interested in macro-nutrients, I had a look into extending my application to gather more data. Unfortunately this resulted in a complete rewrite, as the approach I took in March relied on … [Read more…]
Yesterday I have released a new page on this blog, which describes my most recent project: a smart home dashboard using an Inkplate 10 e-ink display and Home Assistant as a backend. Home Assistant displays a lovelace view of the dashboard which is then rendered to a JPG-image. The Inkplate wakes up every 20 minutes … [Read more…]
For my current personal project in developing a dashboard, which displays metrics of my servers and devices among other things, I was faced with the challenge to collect metrics from all devices. Usually solutions like Prometheus are quite famous for use cases like this, but I did not want to open any ports on any … [Read more…]
Recently I started playing around with Home Assistant, to make my home smart and display useful metrics on a dashboard, e.g. calendar events. A few days ago I noticed specific calendar events crash the Home Assistant integration for a day. I don’t think this is exclusive to my environment and may be a global issue. … [Read more…]
This approach is not maintained anymore by me, as I switched to a new tool, which I posted about here. For my recent activies in calorie counting I used an excellent app called fddbextender which works with the large database of fddb.info. Unfortunately there are no statistics and graphs in the free version. If you’re … [Read more…]
Setting up the environment During a current project I looked into HomeAssistant as a central component / hub for home automation. When starting out with HomeAssistant it is recommended to install the software either as a OS distribution (HASS OS) or run a supervised installation, which is just a couple of fancy bash scripts that … [Read more…]
For a small project (a microcontroller with a temperature sensor) I needed a mqtt broker to process the sensors data to display it in Grafana. There’s already a TIG stack running on my server, so it was obvious to me that I will go with Mosquitto. For some reason Mosquitto never returned any data scraped … [Read more…]
Recently I tried to make use of the renderer function in Grafana to retrieve a graph as an image for further usage. However since Grafana 7 (I guess) they decided to not include the external image renderer anymore in the Grafana Docker image. You may install the plugin yourself, however this does not work by … [Read more…]
Issue: I want to backup specific, existing folders of multiple Android devices. The backup has to be done locally inside the LAN and encryption at rest is a must-have. tl;dr: Resilio Sync hosted on a Raspberry Pi / Odroid / NUC does the job perfectly with their app. Nextcloud is far slower and the FolderSync … [Read more…]
Issue: I need to get a notification if a necessary volume on my Linux device is not mounted, as this volume cannot get automatically mounted because a passphrase is required. The curl-request is dependent on the custom DNS (Pi-hole). When setting up my Intel NUC I decided that all my persistent data of the running … [Read more…]
