# ATOM VoiceS3R as Home Assistant Voice Satellite

Turn an M5Stack ATOM VoiceS3R (ESP32-S3 + 8 MB PSRAM) into a compact,
fully offline Home Assistant voice satellite.

What is in here:

- `esphome/atom-echos3r-voice-assistant.yaml` — ESPHome config importing
  M5Stack's official `atom-echos3r-satellite-base` package (I2S audio,
  `voice_assistant`, on-device wake word). Fill in your own keys.
- `docs/build-plan.md` — full step-by-step build plan (Dutch): Wyoming
  voice pipeline (Whisper + Piper), flashing, pairing, troubleshooting.
- `automations/s3r-rooktest.yaml` — first spoken-notification automation
  as smoke test.

Hardware: ESP32-S3-PICO-1-N8R8, ES8311 codec, MEMS mic, NS4150B + 1 W
speaker, IR transmitter. The 8 MB PSRAM enables on-device wake word
(microWakeWord, "Okay Nabu") — no server needed for hotword detection.
