ESPhome

ESPhome will let you control all aspects of the circuit board and customize its features or behaviour.

There are some limitations to the ESP8266 support. You cant’s use FastLED as the most recent version don’t play nice with the Arduino SDK but NeoPixelBus Light will work just fine.

This is a basic configuration which should get you started if you are planning to use Home Assistant.

Create a new device in your ESPhome dashboard, copy the sample code from below and adjust the code. When your are done, press “INSTALL”, choose “Plug into the computer running ESPHome Dashboard”, select your serial adapter. Make sure that power on your ESP8266 with I0 to GND.

After rebooting the device you will get a notification from Home Assistant that a new device was found.

Follow the wizard to get your device ready.
