The idea
Wall switches are the most used control in a building and the least intelligent. The concept keeps a conventional-feeling switch and existing faceplates, and adds local intelligence behind it: presence awareness, local operation and Home Assistant integration without a cloud dependency.
Key decisions
A compute board and a switch board keep the platform modular, so single, double, dimmer and traveller variants share one brain. Mechanical parts should look stock but feel “space age”. Retrofit is incremental — one switch at a time.
Status
The case study covers research, stakeholders, personas, value proposition, ideation, technology and concept evolution. Open questions and validation are documented as such.
