Home Assistant’s contributor documentation adds interactive examples beside the controls and entity properties it explains. Readers can try a light, adjust a thermostat or explore a dashboard without setting up a Home Assistant server; the demonstrations use simulated devices in the browser.
Aidan Timson brings examples to nineteen entity pages and moves seventy-eight card demonstrations across twenty-five dashboard pages onto the same hosted demo system. New guides explain how card authors can put a card, section, view or whole dashboard on their own website, with shared state across its controls.
Timson’s November 6 explanation describes dashboard tabs and internal navigation that stay inside the example rather than changing the surrounding page’s address. The simulation has limits: the entity-page media controls, for example, do not perform normal playback actions.
