IoT

A collection of smaller home automation projects built on open source solutions from others. From magically opening entrance doors to RGB ambience behind every piece of furniture, and a standing desk that obeys Siri.

How I used an ESP, Magnets and Kubernetes and to solve the great toilet crisis of 2021. A tale of absolutely necessary workplace optimization.

How I taught my apartment’s entrance door to recognize me and open automatically. A surprisingly practical tale of BLE authentication, hidden ESPs, and the occasional accidental door opening while driving by.

When your loft flat turns into a sauna every summer, the logical solution is obviously to reverse-engineer a decades-old proprietary bus protocol. A tale of digital archaeology, improvised level shifters, and ladder-based near-death experiences.

How I reverse-engineered my electric sofa to work with Home Assistant using an ESP32. After frying a transistor and some emergency soldering, I now have a voice-controlled couch.
