* Initial commit * Add error handling to config flow Change unique identifyer to name Clean up hound comments * Ensure hass home zone is created with correct entity id Fix failing tests * Fix rest of tests * Move zone tests to zone folder Create config flow tests * Add possibility to unload entry * Use hass.data instead of globas * Don't calculate configures zones every loop iteration * No need to know about home zone during setup of entry * Only use name as title * Don't cache hass home zone * Add new tests for setup and setup entry * Break out functionality from init to zone.py * Make hass home zone be created directly * Make sure that config flow doesn't override hass home zone * A newline was missing in const * Configured zones shall not be imported Removed config flow import functionality Improved tests
