Home Assistant controlled garden watering part 2 - are you ready? In my previous post, I explained how I measured the level of water in our garden cistern using ESPHome. In this post, I will describe...

Watering your lawn and plants around the house wasn't one of my favourite things to do. This had to be done better - fully automatically and without intervention.

Home Assistant & Arlo cameras go better very well. I'm using it since our entire setup got migrated from OpenHab to Home Assistant and I'm happy with the setup.

My daughter Mia is a huge dinosaur fan, almost a little dinosaur nerd. We are overwhelmed with information about dinosaurs every day. It starts during breakfast and doesn't stop before she falls...

In this post I will briefly describe my personal website's history. It started in 1998. At this point, I have already gone through six iterations. I had already completely forgotten two of them. My...

I would like to show you my new half 30 minutes no coding holiday Home Assistant project.

The dollhouse Mini TV is a small Arduino project using a ESP8266 chip and an SSD1306 OLED display to build a small working TV for my daughter's birthday.

Today I want to share a little holiday project I build this week: a mailbox sensor to make a dumb mailbox smart and notifying us if we got new mail. I’m talking about real physical mail here - letters, postcards, newspapers etc. dropped into our mailbox.

Our Home Assistant setup is pretty simple - everything currently runs on a single board computer - smooth and stable for 12+ months. This is how our setup looks like.

My second Home Assistant project is about the integration of the Homematic HM-Dis-EP-WM55 e-paper display in my HA setup. I am sharing some reusable scripts for this or similar devices.

This project is about the change I did from OpenHab to Home Assistant for our smart home automation system. Ok maybe the headline sounds a bit too sensational but change our entire home automation setup from one system we used for 2+ years now to a completely new one requires quite some heavy lifting.

A flame-throwing Jack-O-Lantern is a real Halloween highlight and definitely something to impress the trick-or-treaters and your neighbors. An internet controlled IoT flame throwing Jack-O-Lantern is even better.

Halloween is coming in a few days and here is the first of my Halloween projects for 2018 - a creepy pumpkin watching you. Every step you take, every move you make is seen by this little guy.

This project is a simple bidirectional gateway to transmit and receive 433Mhz RF signals connected to MQTT. It is built with a cost-effective ESP8266 WiFi chip, simple 433Mhz RF modules and an additional BMP085 sensor.

The mqtt-bme280-homie project is a small and easy to integrate temperature, air pressure and humidity monitoring solution with an extra SSD1306 OLED display. Sensor data is send via MQTT and displayed on the small screen.
