About

Entity Notes adds a notes panel to Home Assistant entity and device dialogs for keeping maintenance details and reminders. Notes can be written in Markdown with a toolbar, and Jinja2 templates can be previewed before saving. Each note shows when it was last updated, and notes are kept in Home Assistant storage and included in regular backups. Services and REST endpoints allow notes to be managed from automations and scripts, and the work stays local. Options cover the editor display, such as hiding the toolbar or preview button, a confirmation before deleting, maximum note length, and automatic backups. It is set up in the UI and installed through the Marketplace.
