esphome-yeelight_bs2

Installation

Create a folder named custom_components in the folder where your device's yaml configuration file is stored. Then clone the the Github repo into a subfolder yeelight_bs2. For example on the command line:

# mkdir custom_components
# cd custom_components
# git clone https://github.com/mmakaay/esphome-yeelight_bs2 yeelight_bs2

Your folder structure should now look like:

config
├── yourdevice.yaml
├── custom_components/
│   ├── yeelight_bs2/
│   .   ├── README.md
.   .   ├── yeelight_bs2_light_output.h
.   .   .

Then add the required configuration to your device's yaml configuration file. For an example file, take a look at doc/example.yaml in this repository.

On a Rapsbery Pi with HomeAssistant and ESPHome as a plugin, the directory should be:

/config/esphome/custom_components/yeelight_bs2/

config
├── epshome
│   ├── yourdevice.yaml
│   ├── custom_components/
|   .   ├── yeelight_bs2/
│   .   .    ├── README.md
.   .   .    ├── yeelight_bs2_light_output.h
.   .   .    .

See doc/FLASHING.md for hints for opening and flashing the light.

Issue: the device keeps losing its connection to Home Assistant

This is not a problem with the device or the custom firmware, but a problem in the upstream library "AsyncTCP". I did identify the issue and have a proposed fix for it. The issue was reported at:

https://github.com/me-no-dev/AsyncTCP/issues/116

If you want to try out this change, then create a libs folder in the folder where your device's yaml configuration file is stored, and clone the following repository into that folder:

https://github.com/mmakaay/AsyncTCP

For example on the command line:

# mkdir libs
# cd libs
# git clone://github.com/mmakaay/AsyncTCP

Then add a pointer to this folder from within your device's yaml configuration file, using the lib_extra_dirs option. Provide it with the absolute path to your libs folder. The relevant part of the config change looks like this:

esphome:
  platformio_options:
    lib_extra_dirs: /config/libs

This way, the repository version of the library will override the version of the library that is bundled with ESPHome. Build the device firmware and flash the device like you would normally do.
