Export nutritional data diary from FDDB.info

August 28, 2021 by Tobey Leave a Comment
fddb-logo

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…]

Project: Smart Home Dashboard

August 2, 2021 by Tobey Leave a Comment

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…]

Datadog as an intermediary for gathering metrics

July 31, 2021 by Tobey Leave a Comment

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…]

Specific calendar events crash the Home Assistant integration

July 25, 2021 by Tobey Leave a Comment
Home Assistant

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…]

Inkplate

A few days ago I finally received my Inkplate 10 in the mail. I’m using this 10″ e-ink display to show a dashboard of my smart home using Home Assistant. When I started playing around with the device everything seemed to work great and I was able to display the example images (and the ones … [Read more…]

Creating self-signed wildcard-certificates for modern browsers

May 30, 2021 by Tobey Leave a Comment
OpenSSL

When setting up my local K3s on a Intel NUC I thought it would be nice to use Ingress resources to access the services instead of using a node-port. As those services will only be used inside my LAN (and I didn’t want to have an invalid certificate warning) I decided to use a self-signed … [Read more…]

DIY Smart Home Thermometer / Humidity Sensor with ESP32 and DHT22

April 4, 2021 by Tobey Leave a Comment
ESP32

As I got further into the Smart Home game, I encountered a type of device I’ve never thought of using: microcontrollers. Reading into the possibilities I recognized these little things as a power and cost efficient way of handling different (light) tasks. Because I’ve already had a DHT22 lying around, which was used with a … [Read more…]

Export daily calories from fddb.info to a database

fddb-logo

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…]

Subtract subquery constant in InfluxDB / Grafana

February 27, 2021 by Tobey 1 Comment
influxdb

The need for a query Some time ago I’ve decided to gather information from my FritzBox router to display in Grafana. I stumbled upon a TIG (Telegraf, InfluxDB, Grafana) stack on Github, which I forked and dockerized. I found a Grafana dashboard to import on another fork (included in my fork as well) which is … [Read more…]

Read external InfluxDB in Home Assistant as a sensor

February 20, 2021 by Tobey 8 Comments
Home Assistant

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…]
