Hello I'm ...

...Markus Haack, a developer, a engineer, a husband of a wonderful wife and a proud dad, based in the beautiful city of Leipzig, Germany. I have a bachelors in computer science and even a good old Dipl-Ing lol.
Currently I'm a Senior Technical Lead at Adobe working on commerce and Adobe Experince Manager.

My Latest Projects

Stuff I worked on recently

  • Home Assistant - Homematic HM-Dis-EP-WM55 e-paper display

    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.
  • Home Assistant - The big move

    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.
  • Dollhouse Mini TV

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

  • IoT enabled Jack-O-Lantern Flamethrower

    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.
