[1.1.0]

Note: This release requires ESPHome v1.19.0 or newer.

It is now possible to address the LEDs in the front panel of the device individually. There are 12 LEDs in total: the power button, the color button and 10 LEDs that are used by the original firmware to represent the lamp's current brightness setting. The output component for the lamp was updated to provide access to the individual LEDs. Check out the documentation guide for details on how to control the individual LEDs.

Made it possible to use lambdas with the preset.activate automation. This makes it possible to link the action to an api service, which exposes the preset functionality to Home Assistant. The example.yaml has been updated with an example for this.
Fixed a rounding error in the slider sensor component. When using custom "range from" / "range to" settings, the maximum value could exceed the "range to" value due to rounding errors. Thanks to Jos for the heads up!
Made the codebase compatible with ESPHome v1.19.0 (PR #1657: Introduce new async-def coroutine syntax) Thanks to @Kaibob2 for giving me a heads up that my code was not compiling anymore!

Note: This release requires ESPHome v1.18.0 or newer.

The GitHub repository structure has been updated, in order to make it compatible with the new external_components feature of ESPHome v1.18.0. From now on, the code from this repository no longer has to be downloaded and installed manually. The example.yaml has been updated for using this new feature. Fixes issue #16.
A fix has been implemented to prevent the lamp from being disconnected from Home Assistant a lot (resulting in the lamp becoming unavailable). ESPHome v1.18.0 or newer is required for making this fix work. Fixes issue #19.
Transitions are now fully suppressed when in night light mode. In that mode, LED output levels are too low for producing good looking transitions. Fixes issue #10.
The example.yaml now uses my own arduino-esp32 unicore build.
Formatted the codebase using the ESPHome clang rules.
The flashing guide got a big update, with detailed pictures for every step on the way.

The known issue documentation page has been removed, now we have a fix for the disconnect issues in ESPHome v1.18.0.

Support for disco mode-style light updates through the light.disco_on and light.disco_off actions. The light.disco_on action can be used to configure the lamp state without delay, without publishing the update and without saving the state. The light.disco_off action will restore the lamp to its last save state, so from before the light.disco_on updates.
Support for configuring light presets, making it possible to mimic the lamp's original firmware feature to switch light color using the color button. This fixes issue #8.
New documentation section: Configuration guide (explaining all the YAML file configuration options).

The component was renamed from "yeelight_bs2" to "xiaomi_bslamp2". The reasoning behind this can be found in issue #7.

Component "text_sensor" that publishes changes in the light mode ("off", "night", "rgb", "white"), This fixes issue #6.
Documentation improvements and a better example.yaml.

All light modes for the lamp have been implemented:
- RGB light (colored light, based on red/green/blue and brightness)
- White light (based on color temperature and brightness)
- Night light (either RGB- or White light, but highly dimmed; enabled by setting brightness to 1%)
Component "light" for controlling the LEDs.
Component "binary_sensor" that act as touch/release sensors for power button, color button and slider.
Component "sensor" that report the level at which the slider was touched.
Component "output" for controlling the front panel light and its level indicator.
