Bjoern Boeckle

Bjoern Boeckle is a German indie developer whose compact portfolio is anchored by mqtt-presence, an open-source utility that turns any Windows machine or Raspberry Pi into a presence-aware endpoint. Written in Go, the utility subscribes to user-defined MQTT topics, evaluates payload values against configurable thresholds, and triggers immediate or delayed system shutdowns, wake-on-LAN packets, or GPIO pin toggles on a Pi. Typical deployments include home-automation hubs that power down PCs when occupants leave, digital-signage controllers that switch off displays after hours, and energy-saving routines for 3-D-printer farms or render nodes. Because the executable is single-file and configuration is handled through a concise YAML file, integrators can embed it in kiosk images, schedule it via Task Scheduler, or containerize it with minimal overhead. The program respects TLS client certificates, last-will messages, and QoS levels, so it slots cleanly into existing Mosquitto, HiveMQ, or Home-Assistant broker hierarchies without additional middleware. Users frequently pair it with room-assistant, OpenMQTTGateway, or smartphone GPS apps to translate presence events into concrete power savings or security lockdowns. Development is public on GitHub, releases are signed with SHA-256 checksums, and binaries are supplied for x86, x64, and ARMv7 so the same binary can run on everything from a Surface tablet to a Zero 2 W. The publisher’s software is available free of charge on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the newest build, and can be queued for batch installation alongside other applications.
