- Smile:
- Make homekit emulation an option (like scan-interval)
- Make explicit that this is (most probably) non-core functionality
- Reference for [Core PR 65808 / `scan_interval`](https://github.com/home-assistant/core/pull/65808) `If you need to customize the interval, you can do so by disabling automatic updates for the integration and using an automation to trigger homeassistant.update_entity service on your preferred interval.`

- Fix issue where notifications would cause an error (see issue 238)
- Restore Homekit-functionality present in v0.20.1 and earlier versions
