# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [1.2.0-RC1]

**Note**: This release requires ESPHome v1.21.0 and Home Assistant 2021.8.0 or newer.
The code will compile with ESPHome v1.20.0, but the lamp will not be controllable
through the Home Assistant GUI when using Home Assistant 2021.8.0 or newer.
Only turn on/off and brightness will be available, not the RGB and Color Temperature
tabs..

### Added
- Preset identifiers (`group` and `preset`) for the `preset.activate` action are now
  validated at compile time. This prevents us from building a firmware with incorrect
  preset identifiers. Before this change, using an invalid preset name would only
  result in a warning message in the device log.

### Changed
- The code has been made compatible with the new color mode support in Home Assistant.

## [1.1.0]

**Note**: This release requires ESPHome v1.20.0 or newer.

### Added
- 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](https://github.com/mmakaay/esphome-xiaomi_bslamp2/blob/main/doc/configuration.md) 
  for details on how to control these.
  Thanks to @Stewie3112 for the feature request that triggered this development!
- Implemented support for visual feedback during the OTA update process in the
  `example.yaml` file: the light becomes blue during flahsing, the brightness slider
  represents the progress, on failure the light flashes red and on success the
  light flashes green.

### Changed
- 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](https://github.com/esphome/esphome/pull/1657))
  Thanks to @Kaibob2 for giving me a heads up that my code was not compiling anymore!

## [1.0.0]

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

### Changed
- 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](https://github.com/mmakaay/esphome-xiaomi_bslamp2/issues/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](https://github.com/mmakaay/esphome-xiaomi_bslamp2/issues/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](https://github.com/mmakaay/esphome-xiaomi_bslamp2/issues/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.

### Added
- New documentation section: Technical details (it's all about the internals)

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

## [1.0.0-RC1]
### Changed
- The documentation has been restructured.

### Added
- 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](https://github.com/mmakaay/esphome-xiaomi_bslamp2/issues/8).
- New documentation section: Configuration guide (explaining all the YAML file configuration options).

## [1.0-beta]
### Changed
- The component was renamed from "yeelight_bs2" to "xiaomi_bslamp2".
  The reasoning behind this can be found in [issue #7](https://github.com/mmakaay/esphome-xiaomi_bslamp2/issues/7).

### Added
- Component "text_sensor" that publishes changes in the light mode ("off", "night", "rgb", "white"),
  This fixes [issue #6](https://github.com/mmakaay/esphome-xiaomi_bslamp2/issues/6).
- Documentation improvements and a better example.yaml.

## [1.0-alpha]
### Added
- 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.
