- The author encounters smoke from a boiler room in a greenhouse that should not be using gas, highlighting the difficulty of accessing and correlating data across siloed building management systems.
- Building data is often controlled by vendors through proprietary systems, leading to lack of interoperability, high costs, and limited access for non-engineers, a situation described as 'enshittification'.
- The EU Data Act (effective from 2025/2026) provides legal leverage for businesses to demand machine-readable access to their data, shifting ownership rights.
- Home Assistant is presented as a mature, open-source platform for data control, emphasizing principles like user ownership, no vendor lock-in, and durability, suitable for business adaptation.
- The Model Context Protocol enables AI assistants (e.g., Claude) to interface with unified data, allowing plain-language queries and democratizing access to building insights without specialized skills.
- The system is designed to be maintainable by non-specialists for day-to-day tasks (e.g., dashboards, automations), while core infrastructure remains documented and standardized to ensure institutional independence.
- Plain-language interfaces remove barriers for diverse users (e.g., botanists, financial controllers), making data actionable without intermediaries or technical expertise.
- Organizations are urged to take incremental steps: test data integration with tools like Home Assistant, inventory existing systems, and leverage the Data Act to reclaim data ownership from vendors.
