COACH explores how people can better understand and influence autonomous energy systems. Through the Lucci device and a human-centered design approach, the project turns complex energy decisions into simple ambient signals, helping communities engage more directly with renewable energy and the transition toward shared, sustainable autonomy.

COACH investigates a practical way for citizens to relate to autonomous energy systems by making their actions visible and understandable. Today, many decisions in distributed energy networks happen out of sight, and this often limits trust and participation. The project responds to this issue by developing Lucci, a small ambient device that translates system behaviour into clear light, haptic, and audio cues.
The work is carried out over six months at Bauhaus-Universität Weimar and brings together user research, explainable AI, and sustainable hardware development. Early activities focus on interviews and co-design sessions that help identify how people interpret energy information and what they need in order to feel in control of automated decisions. These insights guide the design of a communication language that allows Lumina to convey the reasoning behind system choices in an intuitive way.
As the prototype becomes technically and materially refined, it is tested with local participants who provide feedback on clarity, usefulness, and acceptance. The project concludes with an integrated system, open-source fabrication guidelines, and a structured methodology that can support similar initiatives across Europe.
