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.)
