## Build & Install
|
||
|
|
|
||
|
|
* Install ESPHome via Home-Assistant Supervisor
|
||
|
|
* Upload all needed files via the "File editor" into `config/esphome/` and subdirectories.
|
||
|
|
* rename secrets-example.yaml to secrets.yaml and fill in your credentials
|
||
|
|
* Choose your device and flash the firmware. Use ESPHome "Install" -> "Plug into this computer". (Subsequent updates can be done wirelessly.)
