# Mittzon Standing Desk: decoding the LIN bus for Home Assistant control

> The Mittzon Standing Desk project investigates the LIN bus between an IKEA Mittzon desk controller and its handset. Its ESPHome configuration reads position frames through an ESP32 and controls the desk by electrically emulating panel buttons, exposing height and movement controls to Home Assistant.
